Are there any Constant Aperture, MF Standard Zooms?
View previous topic :: View next topic

I'm normally more of a prime lens sort-of-a-guy (I primarily shoot video as well), but I've been finding that the majority of my work has been coming from documentary/reality TV/news reel style shooting, which lends itself to constant-aperture zooms far more than it does fast primes. As such, I've been looking into investing in a constant aperture zoom for my 7D. I've read quite a bit about the Canon 24-70 f/2.8 (both versions), as well as the 24-105 f/4 (I've used it as well).

Are there any older, Manual Focus constant aperture standard zooms that are worth looking in to rather than investing in the Canon L series (or their other AF competitors)? Or is the only way to get a manual aperture ring on a constant aperture standard zoom lens via a Dulcos cine-conversion of an AF lens?

Thanks for any advice that you have.

PS- I started another thread in the AF section asking more specific questions about the various AF constant aperture lenses I'm considering. I wasn't sure where to put the thread if I was to make it one post, so I thought I'd split it into two. The AF thread is seen here: http://forum.mflenses.com/help-with-constant-aperture-standard-zooms-t55073.html

if you need lens primary for video, I wouldn't recommend any zoom other than Canon L because of CA,flare and ghosting handling... because on video it's much harder to edit the artifacts than on photos... old zoom just can't perform nearly that much good as L zooms... situations is better with some older mf primes...

I'm not aware of any high quality, fast, constant aperture zooms that will fit Canon EOS cameras other than the Contax Vario-Sonnar 35-70/3.4 which is incredible. I'm currently looking at the Tamron SP 24-70/2.8 VC though as it has a much wider end, stabilisation and great image rendering similar to Zeiss lenses. Expensive, mind you.

I think the Angenieux / Tokina 28-70 2.6-2.8 also have manual versions.

But the Angenieux branded is probably very expensive?

Contax 3.4/35-70
Contax 3.5/40-80

He asked for zooms with constant aperture.

Some independent zooms you could add to the list are the Vivitar Series 1 35-85mm f/2.8 (varifocal, so possibly not ideal for video?), or the Tokina AT-X 35-70mm f/2.8. Both were available in EOS-friendly mounts such as Nikon or M42.

You might consider Nikon G or DX lenses, used on a suitable EOS adapter with its own aperture control. These tend to be stepless, though possibly not smooth enough for video?

+1

I think the Canon coatings are as good as they get and this makes a huge difference in some applications.

^^ thats the main reason... he can find sharp manual zoom, but hardly with acceptable level of artifacts control... hdslr video is completely different thing than photos regarding postproduction, and the lenses should be as much good as every videographer can afford...

Olympus Zuiko OM 35-80/2.8

Problem is its 1KEUR

EDIT: problem 2, it doesn't fit Canon

go for the tokina 28-70 2.6-2.8. or 28-80.
it is great for video since it has a long focus rotation with hard stops. the lens barrel does not get longer when focusing or zooming.
It is nearly parfocal and your camera will not recognize the 2.6 anyway.

There is also the Tokina 28-85mm f/4 and Tamron SP 35-105mm f/2.8 (AF and Adaptall-2 versions).

I can vouch for the Tokina AT-X 35-70/2.8 lens. Its excellent.

Vivitar Series1 24-48 / 3,8 - probably my favorite lens on my Pentax, I have no experience of video so I don't know if it would be suitable. But it isn't that popular - the 35-85 is the more sought after - so it's cheaper.

Laughing f/2.6-f/2.8 a difference of f/0.2 can be seen?

If you don't mind using an adapter, you could consider the Nikkor 80-200mm f4, Nikkor 50-135mm f3.5, Nikkor 35-200mm f3.5 (only changes aperture if you go to macro).

Just to clarify, the Angenieux and the Tokina are NOT the same lens, even if sellers of the Tokina would like you to believe that. Tokina based the lens on Angenieux designs but altered it so it could be produced and sold for a much lower price.


If you need a long range I would recommend the Tamron 35-105/2.8. There also is a 28-105/2.8 version, but that one is not as well regarded (haven't tried it myself though).
