Craig,
Welcome to the forum! As Pete mentioned, what kind of images do you take? That is really important in deciding on the platform that you will end up with. You say that you are shooting Canon currently, what do you want to gain in the upgrade?

If you are shooting studio, then all of the platforms you mentioned will work. Action,…[Read more]

Hi Craig,

Welcome to the forum. Before giving an answer it would be very helpful to know if you are a professional, a hobbiest and where & what genre you are mainly shoting.

I guess there are shot on a tripod? Would like to see some handheld as well. 😉

Looking forward to the whole report.

Cheers.

Pete,

These were all shot on a Gitzo 5-series with the Systematic Hydrostatic Ball Head. The lens weighs 9lbs alone, hardly hand-holdable,…[Read more]

Doug,

I would assume so, as the image circle limitation comes from the focus module not the lens head.

With the larger 400/560/800 lens head and the 1.4x, you'd have a drool-worthy 560mm f/4 on the S2!! 😎 This is equivalent to a 450mm in 35mm land.

What a great 400mm set-up for the S2!!! After the the dust settles, please compare with the Pentax 6×7 400mm ED lens.

Phil,

Our 400mm P67 lens has been on loan to a forum member here and is on its way back to us for comparative testing. Even without a side-by-side, it's safe to say that the…[Read more]

Thanks for posting,
Arif

Arif,

I'll post all the details in my article, but no, this isn't done via an adapter. The lens has to be shortened to achieve infinity focus. This also involves moving the aperture…[Read more]

Another one, also shot wide-open…

1/350th @ f/4, ISO 320

One from yesterday's testing with the 400mm.

Leica S2 with 400mm f/4 APO-Telyt-R

Yes. The Nikon SC-28 or SC-29 cable has the same pin locations that Leica uses. The SF-58 functions perfectly when used with the cable.

Great idea. Ever since accidentally scratching the the sensor in my S2 while cleaning, I have become very paranoid. A dust reference frame could be beneficial.

Thanks Phil.

I sent your E-mail on to my friend. Thanks for the info- ir sounds like you are wll informed.

The vertical plate on my RRS bracket is only about 1 inch in length and I can clamp along the entire length but the bracket is way off-set from the center of the clamp. It seems stable.
