This is pretty extreme. I don't think it has anything to do with the lens or the adaption. My guess would be a processing error maybe by the camera or inside lightroom, because you left some ...

This is a German page describing the differences (via Google translate you should be able to understand it all): Mamiya ZE There are adapters available, I had a fotodiox adapter for Sony E (without ...

True, the corners of the G28 on a Sony A7 sensor are bad. But using a front filter solution at least the G28 is very usable (which it is not without the front filter). The G45 and G90 are great as ...

I have a big mix of adapters and lenses (also a fan of the Meyers - love my 2.8/100 and 1.9/58), but if I had to choose just one adapter and the lenses that go with it, right now it would be ...

Contax G 2.8/28 with Optosigma front end filter for much better corners on a Sony sensor Mind blowing lens in my opinion.

Congratulations Ernst, on your conversions. I've been interested in building my own adapters with a 3D printer for a long time, but I always shy away because I fear the time it takes to learn how ...

I'm sure you've already considered googleing. The first hit on google Germany is the following: https://camerapedia.fandom.com/wiki/Radioactive_lenses It contains a pretty long list of lenses known ...

A few more from Petri, all of them wide open. The first two: no PP. In case you're interested, I recently did a write-up on Petri Lenses on my amateur blog. Stretching the mossy arms Still some ...

Thank you very much. My images are postprocessed, obviously, but I don't think the 55B lacks contrast in comparison to other vintage lenses, in fact it's quite good and sharpness is excellent if ...

I would think that your lens is broken or internally misaligned. I have the same lens and it can easily be focussed and is amazingly sharp, especially at pretty close distances. Photographing the ...

I guess I'm lucky then. I would find it very hard not to be able to let do some stuff more or less alone. That's my biggest problem also. I'd sell about half without much hesitation, if the price ...

Thanks a lot :-). It's not so easy to let them play outside either. Sure Germany is one of the safest countries in the world, but in the cities there's so much traffic, I hardly let my kids out to ...

Beautiful kids, very nice shots, awesome lens. I try to shoot my kids with manual glass too, but I've somewhat given up, because they hate to be photographed by me, so whenever I try to shoot like ...

This image has some fantastic 3D pop. Very nice.

Some more with the excellent Petri 1.4/55 Auto CC Leaf bokeh Disparate twins (I think @ f/2) Leaf spectacle

I've got another one with the Petri 1.4/55 (@ f/2):

YES! One more suggestion that should be cheaper than the Kamlan: Contax Planar 1.7/50.  IMHO that's a step up even from the Canon FD 1.4/50 which I don't use much. I find it boring. But that's ...

Sounds like you have made up your mind, which was the intention of this thread in the first place. If you need the money from selling the Zoom, just do it. If you feel later, that you need it ...

I really like the rendering of the lens in your images, which is why I'll be keeping my Hexanon 1.4/57. Sharpness in the middle of yours is good and it is what can be expected. If you like the ...

Thanks Alan, I'm pretty sure it's not an artifact it's a lamppost :-). The rendition is the lense's merit, the colors and contrast are just the morning light and the beautiful colors of the trees, ...
