    CY Contax 35-70 on A850!

    FIrst outing in terrible lighting on the A850 CY35-70!

    Always wanted one of these and I think I might be one of the few who have it in Alpha mount!

    The Leitax conversion... was not easy.

    First lens I've ever had in MF where it seems the infinity focus is correct... I hope.

    CY35-70 + ZF 35mm F2 on A850 Samples

    I almost ended up selling the ZF.2 Leitax'd 35mm F2 distagon but I think the beauty of this lens is really using it at F2 for near objects. Somehow the rendering looks better at that setting than at say F4 or F5.6. Sure there's more contrast and detail at higher apertures but the beauty is somewhat diminished.

    As a landscape lens it seems to be a secondary albeit still extremely well executed thought. At F5.6 and higher, I can't tell the difference between it and the 35-70mm much unless extreme pixel peeping. I'll admit I wasn't thrilled with the 35mm F2 on my D7000 but on Full Frame, it really seems to shine. This makes me a bit worried how much I'll like it on my NEX-5N and NEX-7.

    The CY 35-70 was a pretty difficult conversion via Leitax simply because I misread the last step of the process. It should have been about a 2 hour job but ended up being 5 hours. Now that I've done it though, everything else lens surgery related seems easy.
    I really wish I had a chip for the CY 35-70.

    Oh there are a couple from the Zeiss ZF.2 21mm F2.8 also thrown in.

    Jae,

    Thanks for that. I have one of the lenses and I'm procrastinating on ordering the conversion kit. I have a good copy of the Tamron 28-75/2.8 zoom, so I've held off on the Contax over concerns about manual focusing. Given the Contax's reputation as a world-beater, though, I should probably bite the bullet and go ahead with it. I know it's not fair to judge image quality from web reproductions, but I'm addicted to resolution at this point...

    If only I knew that a full-frame with live view was coming from Sony some time down the line!
