    The fastest Alpa mount lens

    My Schneider Xenon 75/2.0 has been mounted and should be back with me mid-Jan can't wait to see how it performs.
    Apparently it covers 6x6 but I anticipate much field curvature. The lens performs extremely well on 35mm in its Arri mount incarnation.

    Very cool! I have the exact opposite with my Alpa mount pinhole lens!

    Re: The fastest Alpa mount lens

    I had some similar vintage SK glass. The resolution was great, but the contrast was low--the downside of no lens coatings. Since I was shooting color film at the time, I was not really impressed. However, with a digital back, these are much more compelling.

    Looking forward to some results...

    Thanks for the insight Will! If I find the low contrast frustrating I'll get the lens coated.

    Thrice, you can probably do quite a bit in processing. Simply bringing the curve down in the shadows would be the start--flare will impact shadows faster than mid-tones and highlights. I think it will be a fun lens and may even have an interesting look.

    Ooh. Very interesting.

    Did ALPA do the mount for you themselves?

    I had the mount done by SK Grimes. I haven't seen it up close yet so I'm not sure of the quality/accuracy of the mount. Time will tell

    Re: The fastest Alpa mount lens

    Ok, I have everything in my grubby little paws.
    Seems like SK Grimes scratched my Alpa Groundglass (pretty badly)

    The lens covers comfortably wide open. I get about 5mm of shift wide open (haven't tested stopped down yet). I seem to be able to use the full 17mm of tilt.
    Alpa should make the tilt adapter usable with the groundglass, as it is currently you cannot mount the groundglass to the tilt adapter so rear movements are very difficult unless you have a live-view back (I don't).

    I seem to have left my card reader at home so I can't see the true quality of the images but they look sharp with a mild glow, not much swirl to the bokeh but a little nisen-bokeh (bright rings) on very bright point light sources.

    I'll test it better tonight and post pics

    Hmm - which tilt adapter do you have? I have the 34mm T/S adapter and it works just fine with the Alpa GG. Also, perhaps it's relevant but also which GG version? I have the latest fine etched with fresnel.

    I typically use the T/S adapter and GG on the rear of the body. (TC or STC).

    Hi Graham,

    I have the 17mm T/S adapter and the latest PGS (item number 310.010.008) as well.
    The tilt knob is definitely in the way of the GG which has quite a large surrounding shroud.

    Cheers,
    Dan

    Re: The fastest Alpa mount lens

    That truly sucks. I am saving for a 40HR SB17 and new SB17 T/S adapter myself as I've been using the PGS a lot more now with my other SB34 lenses for tilts.

    Presumably you can still use the T/S adapter on the front of the camera body though. Just not on the rear? It's not the same effect obviously if you're looking to leverage looming.

    WTF were they thinking to make them incompatible? The older SB34 version that I have works fine because it is controlled between the front/rear flanges on the adapter and so doesn't protrude from the rear.

    Yeah, no problem with front tilts/swings but that groundglass is never going to fit on the T/S 17. I like to leverage the slight distortion and even illumination of rear tilt but it's not a huge issue with a 75mm to only do front movements I guess.

    Low contrast is good for backlit subjects. Suffice to say this lens is sharp and has beautiful bokeh.

    I would like to see an image or three with your pinhole lens. Thanks.

    I have build and used pinhole cameras and pinhole lenses for 35mm format somehow I never thought of it for MF. I'd like to see what you have.

    Hate to point this out, but you can work with f1.2 Canon/Nikon lenses on an Alpa FPS, if fast lenses are your thing.

    Why do you hate to point it out? I know about the fps. They're not native mount, can't tilt and don't cover 645.

    With such a fast lens and no SLR or RF type mechanism, how hard is it to nail focus? I imagine it'd be super hard, especially hand held like I assume the above example is?

    Re: The fastest Alpa mount lens

    It's pretty easy, I used the groundglass but was tripod mounted. Just focus and tell the person not to move any closer or further from the camera. Similar to shooting with LF.

    Really cool to read!

    I had same idea a few years ago but haven't made it to tech camera (yet). I do have an interesting lens to adapt and which I now wish to sell if anyone is interested:

    Schneider Xenotar 100mm 2.8 (latest series)

    Please check for sale section FAST LENS for TECH CAMERA ? --- legendary formula - Hong Kong - Show Ad | getDPI

    I hope it is ok that I posted above info here in this thread.

    Thanks!
