EX3 and 35 mm still telephoto lenses

hi,

I m about to buy an EX3 and use it with 35 mm still telephoto lenses for wildlife work. but I think I need to choose old style lenses with manuel iris ring ? does sony make a 35 mm still adaptor for EX3 ? for example can't we use new nikon or canon telephoto lens with electronic iris ?

thanks,

alkım.

Best way to do it is just to get a simple metal adapter made up (Les Bosher - Camera Engineer or mtfservices.com). You can have one made for Nikon, Canon FD, Leica, PL, whatever. It'll be manual focus and iris, but that's as you'd want it anyway.
Can't use EOS lenses or some newer Nikons 'cos they don't have iris rings.
Sigma make some nice lenses in Nikon mount, 70-200 f2.8, 120-300 f2.8, 100-300 f4, or you could go with primes like Nikon 300 f2.8, 400 f3.5 etc. Look for internal focus lenses as they have light touch focussing rather than having to put too much pressure on the lens causing shake.

I am planning to do exactly the same and I already got few awesome Nikon manual lenses from KEH.com

Look for the Nikon ED manual focus lenses - you can't go wrong.

It'll be the equivalent of about x5 or so.

Thanks Steve;
what about when using 1/2" and 2/3" lens stock?
I assume there is no multiplier for 1/2" lens but what about 2/3"

Focal length of lenses never changes, it's all down to sensor size. So any lens made for a larger sensor will have more magnification when used on a smaller sensor. If you take 35mm frame size as being x1, then 2/3" is x3, 1/2" is x5 and 1/3" is x7 (roughly). So you can work them all out from that - so a 2/3" lens on 1/3" camera will have double the magnification that it would on a 2/3" camera etc.

I saw steve's recommendation of Les Bosher's lens adapters - I've emailed him asking about an adapter for 2/3" lenses that I have that could possibly be mated to my JVC 5000 & 500 1/2" mounts.

Alkim, if you were desperate to use the Nikon 200-400 then a lens engineer could I'm sure fabricate an aperture ring for it, but would probably be very expensive.
How about a long 2/3" lens for you guys? Maybe a Canon HJ22x7.6 (goes upto 350mm or so). The Canon HJ18x28 is probably the lens of the choice at the moment for wildlife (certainly my favourite), but it is very expensive (about £25,000). Optically it's great, relatviely light (2.5kg) and upto 1000mm.

Hi Steve

I'm based in Pembrokeshire. Have you tried the EX3 plus Nikon lenses? If so, how would this setup compare with a Varicam.

Thanks

Haven't used the EX3 yet, but may do soon. Was put off it after I tried EX1 on flying bird and hated it (see my post on it, long story!)
You can get an adapter no problem, and I'm sure they'll look great. I'd go for a Sigma 120-300 f2.8 probably. If I do get to play with one I'll try and get my Canon 150-600 on it.
The images from the EX1 in still frame looked amazing, and the whole system worked pretty well. Viewfinder was crap though, much better in EX3 I gather.

logical way is to go with sigmas zooms at these conditions.

steve I ve used some 2/3" lenses. they are superb and much more easy to use but as you mentioned too expensive...

It will be interesting if the nanoflash makes this a serious professional wildlife camera.
