Would OM lenses make a good, consistent set for video?

After collecting a small assortment of seemingly random lenses to use with video, I've realized I need to stop picking up random lenses and build a set of consistent lenses I can use for video work... on my last shoot, I shot with 4 lenses from 4 different makers/eras, and it was impossible to get a consistent look in post. My first inclination was to try to build a set based on my favorite from the bunch (a Leica Elmarit-R f2.8/90 - love that Leica look), but trying to put together a fast set of Leica-R lenses is likely to cost as much as a set of cine lenses. So I've reconsidered my other lenses, and as I really like using the Olympus f1.4/50, I'm wondering if the rest of the OM lenses (probably of the f2 variety) have a consistent look across the line? Overall, they seem reasonably priced. Any thoughts?

Oh, and the cameras I'm shooting on have EF mounts (but different crop factors), so whatever I end up with needs to be adaptable to EF

Personally I think that OM is the best legacy option for EF mount since you can switch lenses without pulling out the adapter. The problem is availability and prices - tele Zuikos in f/2.0 cost more then Canon AF analogs, and are fairly rare, wide 2.0 are more common but also run in hundreds of dollars.

I have quite a lot of Zuikos, and they are always fine lenses. But whether they have the 'consistent' look you want I am not sure because I am not a good enough photographer to know what this really means.

As Gardener has pointed out, the f2 lenses (21mm, 24mm, 28mm, 35mm, 85mm, 100mm) will cost a lot. I only have f2.8 at best (except for 50mm of course).

I have read the the 35-70mm with constant f3.6 aperture is a good lens for video as it stays in focus when zoomed. This is the top spec 35-70mm (there are, I think, 3 others) and is quite pricey, but probably less than the f2's. It is a good lens, though I haven't used mine much. You will need an adapter with the exact correct thickness to benefit from the constant focus though.

If you want a set, you might consider the Samyang primes - almost certainly the best value f1.4 set (apart from the 14mm at f2.Cool. Though you have a bit of a gap between 35 and 85, so you might have to find a fast 50 from a different manufacturer; there are plenty of options for those.

If you have a chance, take a look at US version of The Killing and check out how in intro every 2-3 second cut is very obviously made with a different lens.

+1
50/1.2 from Samyang is already announced for 2014 btw.

thanks for the replies. I was actually on a shoot yesterday and the director brought along 3 of the Rokinon (aka Samyang) lenses she had just bought. Unfortunately, the aperture blades on the 35 got stuck when I closed them down to f11.0, and the 85 flared horribly when I aimed the camera even remotely in the direction of the sun. I ended up not even trying the 24 and just told her and her editor they'd have to play around with different looks in post (it was for a music video, so she was fine with it). So based on that bad experience, I think I'm going to avoid them (however, I think I also like the idea of using an old set)

I've found that some of the wider f2 (especially 28 & 35) seem to be available for somewhat reasonable prices (like $200-250), and I was debating just picking up the 21/f3.5 for cheap until I can find the f2 for a good price

but in addition to the consistent look, I was also wondering about the focus throws - do they tend to be fairly long or short?

I haven't looked into that one because I've been trying to find a set I can use consistently around 2.8. I did read about the 35-80/2.8, and I've definitely considered it after what I've read, but it's not cheap either, and I figured it'd need to be stopped down to at least 4.0

The availability of so many lenses rated at f2 is the primary reason I'm interested in it. And due to the crop factors I'm working with (1.6 for APS-C and ~2.4 for BMCC), I don't think I'll need too dramatic of a tele. Right now, I'm leaning towards trying to build to 21, 28, 35, 50 & 85

Asahi Takumars have very consistent 'look' -- color, contrast -- and feel...

35/2, 50/1.4, 85/1.8, 135/2.5

No different than M42-EF Wink

I hadn't considered the Takumars, although I have picked up a few m42 lenses - is there a fairly fast Takumar around the 18-24 range?

I just measured a few OM lenses:

21/2 has a focus throw of 50mm (of 190mm)
35-80/2.8 has a focus throw of 57mm (of 220mm)
50/2 macro has a focus throw of 160mm (of 197mm)
90/2 macro has a focus throw of 180mm (of 218mm)
100/2 has a focus throw of 155mm (of 187mm)

Measured a bit randomly, there are thinner and thicker parts on the lenses. At least % or degrees can be calculated if needed.

wow, thanks! I was hoping for a vaguer "they're pretty short/long/about normal" response, but the detail is appreciated!
