Title: 35mm lens options for Cambo Actus
Post by: XavierYoung on November 15, 2019, 01:04:45 pm
I'm about to take the plunge switching to the Cambo Actus with Sony A7riv but need a 35mm lens option. Does anyone have any experience of the 35mm Actar (modified Contax 645 lens) or any other options? The Pentax 35mm f3.5 seems like a possible alternative? Any other suggestions?

Thanks

I am using the Zeiss 35mm converted by Cambo and it's a stellar lens!

Thanks Meierruedi,

That's kind of what I needed to hear before before spending £750 ruining a £700 lens. Which camera are you using with that? Any other recommendations?

Best, Xavier

Hi Xavier

I am using it on the Cambo Actus Mini + Nikon D850.
I tried it with my Z7 on the Cambo-GFX + AC-784 adapter to see if there is more rise/fall without the mirror box. Unfortunately there isn't.

The Hasselblad Carl Zeiss Distagon 4/50mm (latest edition) is stunning as are some old enlarger lenses: the Rodenstock Apo-Rodagon 4/80mm and the Schneider Componon-S 5.6/100mm are incredible! As one would expect with enlarger lenses they yield a very flat field with little aberrations. Definitely worth getting them. Don't forget to tape over the illuminated f-stop indicator both on the in- and outside of the lens.

The Actar 24mm is good if you get a nice copy.

Correcting distortion is always an issue with the 24mm and the 35mm if you live inside Adobe. PT-lens was kind enough to provide a profile for the two lenses but you should not forget to get a centred  (no shift, no rise or fall) exposure...Maybe I should give Capture One a try...Anybody any experience?

All in all I really love to work with this kit!

Cheers
Ruedi

On C1 Pro is pretty easy to correct shifted distortion (as well as lens vignetting and sharpness falloff).
You can manually add a shift value for both axis and save it to presets to recall it with one-two clicks or style.
