impressive images. The image covers all S2 sensor? if yes, you’ve got the Holy Grail!

Yes, the projected image covers the entire S2 sensor with no vignetting.

How fascinating! David, Will I have to do permanent changes to my APO-telyt or can I manage via an adapter?
Thanks for posting,

Thanks for posting,
ArifArif,
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 ring and mechanical linkage back towards the front of the lens. Because of this, I don’t think the 1x module will work, only the 1.4x and 2x.
If you are interested in converting your lens, let me know.

Hi David:
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 Leica eats the Pentax lens for lunch. Much, much sharper. Easier to focus. Better contrast. Better build quality. The Leica can be used wide-open without penalty. The Pentax really needs to be shot at f/6.3 or f/8 to extract the best sharpness and then you are fighting shutter speed.
We will post results of our tests when we receive the lens next week and do some shooting.

WOW! That is really great.
I guess there are shot on a tripod? Would like to see some handheld as well. 😉
Looking forward to the whole report.
Cheers.

Hi David:
Leica lenses eat everything for lunch at wide open apertures. My Pentax 400mm tests confirm that the performance is disappointing wide open but greatly improves stopped down 2 stops and even better at 3 stops. In long lenses there is no free lunch. What is the going price for the Leica APO 400mm and modification?
Thanks for running these tests

Should we assume the larger lens head would work too?

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.

Pete,
These were all shot on a Gitzo 5-series with the Systematic Hydrostatic Ball Head. The lens weighs 9lbs alone, hardly hand-holdable, especially in 92 deg F heat and 80% humidity (my test conditions yesterday). I’m assuming you were kidding though. 🙂

Phil,
My own Pentax 400mm testing yielded the same results. Unfortunately, shooting birds at f/8 – f/11 just doesn’t cut it when I was already fighting 1/125th shutter speeds at f/4.
The modification cost is $1200. The lens combo we have is selling for around $6500-7000. Unfortunately, the 1.4x is far less common than the 1x module.

David,
Thanks for the reply. as luck would have it, I have the 1x so will wait and see if the 1.4x or 2x shows up as a bargain. I will wait for the details in your article.
Thanks again,

David,
Beautiful conversion of the lens. It would be an easy way for Leica to provide manual focus long glass in a short time, just convert the focus modules like you have. Aside from the fact that the 1x tube is too short, the 1.4x increases the image circle as well, yes? - September 3, 2015 at 5:33 pm #12982Boris MassieuxFrequent MemberFranceJoin Date: Sep 2015Posts: 3Currently using:

I have no 400 nor the module, but the results are amazing. - November 2, 2015 at 3:19 pm #13276
Solms modified my 1.4x tube to work with LeiKo adapter on the S series, I will probably send my 2x tube off next year, They have not done many and it is on the edge of what can be modified, and comes back with lots of disclaimers 😉
