Well, if you want a full set of focal lengths, aim for Nikon. If you want cinema-grade performance, go with the 18-50. Obviously, stepping up to the 18-85 is a much easier choice (ie. Get the 18-85!) but if the 18-50 is your only option, then you've got a tough choice to make.

Think about it, you could buy a 17-35mm 2.8, a 28-70mm 2.8, and an 80-200mm 2.8 zoom lens for about the same price as the 18-50mm 2.8. You'll have full manual control of the lenses and you can carry them up to the FF35 sensors on Scarlet and Epic once they come out.

However, if you're only going to be on S35 sensors, like the current RED One, then you could always try for DX-sized glass like the 17-55mm 2.8 or even, the all in one, 18-200mm 3.5 and use the modified Nikon mount from Douglas Underdahl, which you would want anyway for the Nikon mount right off the bat.

Then, there's always the primes. You could go onto Kenrockwell.com and do some research on which lenses work best for you. But here's some focal lengths you could look at for the price of the 18-50.

20mm 2.8, 24mm 2.0, 28mm 2.0-2.8, 35mm 1.4, 50mm 1.2-1.4, 85mm 1.4, 105mm 1.8, and 135mm 2.8.

That's a good range, but you could go higher, like 200mm 2.8, but it all depends on how far you want to go with primes versus getting the 80-200mm 2.8 for the price of a single higher up prime.

You can mix and match the zooms with the primes too. Plus there's specialty stuff like the 28mm 1.4 prime, the legendary 58mm 1.2 prime, 14mm 2.8 prime, 11-16mm 2.8 DX Tokina zoom, and, if you have the modified Nikon mount and no need for filters, the phenomenal 14-24mm 2.8 zoom. It all depends on your budget and what you're going for.

But realize that with still lenses, you're giving up the robustness of the 18-50mm PL zoom. The iris ring doesn't click, the focus is repeatable (ie. you can mark it for 100% consistency), and it's just designed for filmmaking. But, again, it just depends on your budget and what you're going after.

Thanks for the feedback Zack. I've got a set of Nikons and the RED lens, but for some reason I felt like the RED wasn't as good as the Nikons initially so I stopped using it. Now I'm wondering if I should give it another shot. The only time I used it was for a test a few months back. Of course, without renting additional lenses, I'm limited to 50mm where as with the Nikons I have up to 200mm.

I have the red nikon mount. Maybe I should look at the one you mentioned.

I think it would look about the same.
The big difference is of course the
difference between using still & cinema lenses.

These shoots were with two different cameras
and at two different locations.

I bought all 3 for $3553 :) about half of the RED 18-50

I'd argue about the 18-85. It's an amazing lens and an amazing value. However it's also a monster. Just for me personally, I'd rather get the 18-50 and 50-200. The 18-85 is 10 pounds and a foot long! Plus it requires extra hardware like a lens support. All that makes it almost impossible to handhold or steadicam easily, and just slows down production in general for a small crew.

If the camera's never leaving the dolly then the 18-85 is a better value, but the two 3 pound zooms seem much more versital to me. Plus, i/pin data :)

Function wise, I love them, but to be honest, I'm having significant CA issues and I'm not sure what to do about it. Hopefully some friendly REDusers will help me out.

CA issues on all of them? shit. Thanks for the heads up. I was considering the 17-35, but I read that it isn't sharp opened up.

I just cancelled my birger mount (i have the canon 24-70L and 70-200L).

I was considering the Nikon 85mm (1.4?) and 50mm (1.8?). Or a 24 and 14. Something like that. Just 3 lenses, good but reasonable. Maybe because they're prime they'll be better and won't have CA issues?

Jason Ing
11-17-2008, 10:50 PM
I wonder if AE has a plug-in or feature that will correct the CA like lightroom does? There's got to be a CA correction ability for one of the compositers.

these are Nikon's premier zooms, so I'm going to assume they're just on my lenses. Also, I just noticed the CA, so it might not be all the lenses, maybe just one. I'll find out the next time I shoot.

Red isn't full frame, right? So what is a 50mm on the Red, etc.? I remember a post that figured it out.

Brandon Fraley
11-17-2008, 11:09 PM
remember that Nikon and Canon's DSLR's are not full frame (well, some of them are, but most are not) so a 50mm on your DSLR is about the same as 50mm on RED

As for the 18-50 to compare... It's been discussed here before, lots... But here's my take on the 18-50 vs. Nikon lenses (or other similar still lenses).

The 18-50 offers some nice advantages such as continuous iris (no detents to click into) and much longer throw distance for rotation of focus and zoom. It's measured in T stops for those that are more cine-minded. Overall it's a good lens for the money, especially for a lens that provides cine-style operation. Oh, it also has the /i data contacts. The compact size makes it excellent for handheld and steadicam use. It also has a great close-focus ability. Overall, the lens is rather good optically. Nice contrast, pretty sharp for a compact zoom, good color rendition.

Some of the caveats or trade-offs of the lens is that there were compromises made with the design. Just part of the deal in order to make the desired price to performance ratio. The mechanics can often feel a bit gritty or even loose, it tends to vary from one lens to another somewhat. My 18-50 runs pretty smooth, but I've felt some that are very loose or gritty by comparison. The lens mostly holds focus throughout the zoom range, but I've found the focus to drift a bit if you're racking from one end of the zoom range to the other, a bit more so if going from tele to wide. However, it holds focus better than most still lenses out there. The breathing on this lens is bad. There, I said it, it's awful. It's not an internally contained design, the front element telescopes in and out when zooming. Hence the permanently attached front hood on the lens to protect the lens.

I'll leave the comparative shots to others who have already done them. But I will say that the 18-50 is priced fine for what it is. It's a cine-style lens that performs more like a still lens, but overall fits in between most still photo lenses and cine lenses. It has a lot of advantages. I originally did not purchase this lens with my RED because of all the compromises and some of the gritty feeling ones I had encountered. But I picked one up about 2 months ago and I regularly find good uses for it. I don't own any good PL mount primes right now (holding out for RED primes) and the 18-50 has been a life-saver for steadicam use as it has saved me from renting lenses on several occasions. I just try to not rack focus or zoom much or at all with this lens to avoid the breathing or the occasional gritty motion.

im in the same boat... still vs RED zooms.

The Zeiss ZF look nice though. and a nikon 17-35 f2.8... but still it gets up there... The 18-85 is soo nice but huge and this is an issue for me.

Arggh Dilemma. (add a Epic upgrade and alot of dough in that regard..)

One of my RED cameras has a Nikon mount, and the others have PL mounts. My crews and me regularly use Nikon lenses and PL cine lenses.

We don't shoot narrative cinema (by choice), but we do shoot about every other genre you could name.

The Nikon lenses we use are:

Zoom: 17-35 f2.8, 28-70 f2.8, ED 80-200 f2.8 AF, 50-300 f4.5 AIS

Prime: 14mm f.2.8 AF, 20mm f2.8 AIS, 24mm f2 AIS, 28mm f2.8 AIS, 180mm f2.8 AIS, 400mm f3.5 AIS

Except for the 17-35 and 14mm, I bought each of these lenses used, some from B&H, a few off of Craig’s List, and a few in local photography shops.

We've had very good results with our Nikon lenses - very few obvious problems (CA, vignetting, pin cushion, etc.). All the ones we have are designed to cover full frame 35mm still, thus on RED One, where S35mm is being covered, you’re using the center portion of the lens, usually the strength zone of a 35mm stills lens. Google reviews on each of those lenses and for the most part you'll find very good reviews. That said, each individual lens will vary. If buying new, test the lens out quickly, and if it is sub-par, send it back for another one. If buying used, check the lens out carefully, and if it doesn't meet your expectations, sell it and find another. Once you get a good kit of lenses, treat them well and they will usually perform very well for years.

RED lenses:
I own and have been using the RED 18-50 and RED 300 for the past 15 months now. In general, I agree with what Jeff Kilgroe posted about the 18-50, although mine doesn’t have the gritty feel in mechanics he described, and it doesn’t breathe anywhere near what he described. It is different than most cine lenses in that the front element telescopes – but in our lightweight mobile workflows we rarely use a matte box with the 18-50 and we simply use 72mm screw in filters on it. Optics are the strength of the 18-50. It is crisp, good contrast, nice bokeh, etc. I really like the 18-50, and for the price point in a cine lens, its price to performance ratio is very high. We’ve shot with the 18-50 underwater, in helicopters, on jibs, on stabilization units, etc. – all with excellent results. Is it a perfect lens? No. Is it an excellent lens for to money? Yes. Would I buy it again? Definitely, because it fits our needs well. BTW – the RED 300 is an excellent lens – crisp, good contrast, well built, etc. I’ve had great results from mine.

Field workflow:
Our work is in three different styles: cine style, hybrid cine/EFP style, and EFP style. If you do strictly cine style production, in a non-union environment, with mid-sized to small sized crews (or single operator), the 18-50 could be a good wide-angle cine lens solution for you. If you do large crew and/or union work you may find crews complaining about the telescoping center column on the 18-50 and insisting on the brands they are used to (Zeiss, Cooke, Angenieux). If you do hybrid cine/EFP style or even pure non-hardlined EFP style, with non-union and mid to small crew size, and you sight focus rather than traditional focus pulling, then either the 18-50 or Nikon zooms may fit your requirements (17-35 and 28-70). If your work is destined for the big screen, then generally cine glass should be your choice. For delivery in mediums smaller than the big screen, either cine or 35mm stills lenses may be the ticket, depending on your crew size, crew composition, focusing style, and the genres of production.

RED 18-50 vs Nikon zooms:
In a sense, apples and oranges. If a wide-angle cine lens is within your budget, you frequently find the need for geared lenses, and you need a crisp, small (mobile) wide-angle lens for a relatively good price, then the 18-50 may be your ticket. If you are on a limited budget, want generally good optics, work in crew situations where 35mm stills lenses won’t be a problem, then the Nikon zooms may be the ticket. In artistic and experienced hands the 18-50 and Nikon zooms will all generate very good images on RED One. I own both, I like both, and I've had good results from both.

Looking to the future, I'm very interested in the new RED electronic zoom lenses that were just announced. I definitely anticipate buying them and testing them out in our field workflows.

Note: even though I could have bought one of the very first RED 18-85 zooms available, I didn’t buy one because its size to focal length ratio wouldn’t work well in the mobile production we usually do. If you do more stationary, narrative type work, it would probably be a very good choice.

Hope this insight I’ve given helps answer some of the questions posed on this thread.

If your going to think about using Nikons on your RED, look into converting them 1st. I have a set of Nikon Zeiss ZFs that were modded by Peter Sensor of RPlens.com and this set is so professional both mechanically and optically in my opinion that I am able to rent them with my RED package. Over the last year I have worked on a variety of shoots from Pepsi cola, Avon to PBS pilots and indie features and for me, optics is a huge part when determining the look you want achieve so I would recommend testing out the glass 1st. I owned the RED 18-50 but sold it cause it simply was not a look or feel I was into, but others like it so to each his own right. I am strongly considering the RED 18-85 at the moment and will be renting soon this time around. Test them 1st. Cheers.

What is CA?

Chromatic aberration - in short, fringes of color around an image. Each color in the optical spectrum can't be focused at a single common point on the lens optics. Thus lenses low in CA usually have elements and coatings designed to reduce CA.

What do you test for? How do you go about testing them?

I need help with getting good Nikon glass. I was going the birger/canon route because I've been a canon guy all my life and have some L glass. But I cancelled and now I gotta learn about Nikon glass. So is Zeiss that much superior? I've been reading that Nikon ED or D glass is equivalent to L? Someone said zeiss is equivalent to L.

Anyway, if you could share some info or point in the right direction, I'd appreciate it.

I was thinking of picking up the 85 1.8 as my first lens. Then maybe the 35 or 50. and then a 14? I should be okay after that. I don't think I want to go the zoom route.

What FF are you using?

Thanks!

Thanks for in depth advice.

still confused because i know the importance of good glass but i simply cant afford UP (i normally rent Ultra primes). The RED 18-85 is too big for me.

I have already contacted duclos lenses in regards to having a set of Zeiss ZF modified - dont know what it will cost, but it sounds like it is worth it:)

how is the focus throw on the ZF and how sharp are they compared to UP?

and tell me more why you liked them better than the RED?

Steve Gibby

I've been reading that Nikon ED or D glass is equivalent to L?

In general, Nikon ED or D are equivalent to Canon L. I have Nikon lenses for use on RED, but I also have a Canon DSLR and several L series lenses. Don't overlook Nikon AIS lenses. Though they were built in the late '80's and '90's, many of them are excellent and very good on RED. Note all the AIS glass on my Nikon lens list earlier in this thread. All of them were hand picked for being very good lenses to round out my kits, but also specifically because they were AIS, which was a solid improvement over the previous AI lenses - better lens coatings.

None of my Nikon lenses have been converted to PL or re-housed. When I want a 35mm stills lens for a project it is almost invariably a mobile project with a small crew who will be sight focusing. I also rarely use a matte box or follow focus with my 35mm stills lenses. With practice racking focus with the lens barrel when sight focusing becomes almost 2nd nature.

I do have one 35mm stills lens that was mount-only converted to PL for use on RED One - my Canon FD 150-600 f/5.6L zoom, which was converted to Century PL, with no other modifications to the lens. Its images are stellar - I use it for shooting wildlife and sports.




I was thinking of picking up the 85 1.8 as my first lens. Then maybe the 35 or 50. and then a 14? I should be okay after that. I don't think I want to go the zoom route.

Since it is primes you are looking for, in wide to mid-length Nikon primes, here are some good ones that may suit your needs on a relatively small budget:

14mm f/2.8 D AF, 20mm f/2.8 AIS, 24mm f/2 AIS, 28mm f/2.8 AIS, 35mm f/2 AF D, 50mm f/1.2 AIS, 50mm f/1.4 AF D, 85mm f/1.4 AF D, 85mm f/1.4 AIS, 85mm f/1.8 AF D, 85mm f/2 AIS, 105mm f/1.8 AIS, 180mm f/2.8 ED AIS

Remember, even with a certain lens MM and model, there can be slight to moderate variation in 35mm stills lenses. Test each one out, see if it fits liking and needs, then have fun with it!

looking at footage IMHO isn't great for comparing lenses. Any footage you see has been processed, making comparisons of contrast and sharpness etc not terribly valid, plus, generally all these lenses look great, the big difference you'll normally find is in how you use them (build quality, how they feel etc).

besides that I just don't know of any nikon vs RED lens clip :)

If money was no object, i would love to go out with RED.
But So far so good, I’m actually happy with Nikon17-35mm 2.8, a 24-70mm 2.8, and an 80-200mm 2.8 zoom lens

You can Test lenses in a lab or out in the field, I do both but prefer field test with real subjects...nothing beats a field test for me. I generally cover the basic when testing glass, overall looking for the details and unique characteristics each family of optics tend to yield...how they breath, hold focus, chromatic aberrations, distortion. Some glass is just too sharp for my likings, I lean towards older cinema lenses myself. (Keep in mind I do narrative work)

Obviously its harder to test still lenses cause I dont think you can rent them, so ask your photo friends to barrow some glass and if you dont have those then the good thing about nikon glass is that its cheap so take a plunge at a low risk.

I will say this, old nikon glass is pretty unique and I have always been a fan. The coating on the glass was different 20 and 30 years ago and the images come out softer and more "cine" like imo then new glass which is way sharper. Find a local shop and look at some of the old vivitars, they are much heavier and feel better built then your average plastic modern lens. I found a 70-200 Nikon that was in meant condition from the 70s for less then 300 bucks and it takes incredible pictures...it did 30 years and it still does today.

When buying older glass always visually check the optics for any funk or fungi growth, if the mechanics check out then give it a go. Some stores even give you a week to make sure they check out proper. (there is a way to test glass :) I got some good deals at Adorama in NYC.
