Mamiya press 50mm 6.3 optical formula

[ruilourosa]

Hello

Much have been said about biogon clones, similars, types, names or tradenames or whatever... I´m not interested in that discussion...

I have bought recently a Mamiya 50mm 6.3 optically mint and i have the intention to use it, having already a 75mm and a 127 and being the 75mm really good and the 127 really good also but a tad limited in the corners (a bit similar to yashinon in yashicamat 124) specially wide open.
I wonder how the 50mm will behave... i have a 90 grandagon (5x7) 75mm nikkor sw (4x5), a 65mm super angulon f8 (6x12, almost 4x5), a 50mm bronica pg (6x7), a 35mm mamiya (645) and a distagon zf 18mm (35mm)... i like all of them specially the 90 and the 75mm sw!

i know that the design is a good clue but i wonder who is using it as i just tested it in polaroid (and focusing to 3m @ f11 covers fully the polaroid format) but i cannot see if the fallof is obvious nor if the quality is good.

I own a few super angulon tipe lenses but no biogon type (i know that this is no biogon type as his and that...)

any similarities with swc?

Thanks

You have the lens. You've used it. Why are you asking us whether your lens is any good? Ask the lens.

If you want to see the lens' cross-section, download the lenses pdf manual from here: http://www.butkus.org/chinon/mamiya/mamiya_universal_accessories/mamiya_universal_accessories.htm. Image quality is poor. And decide for yourself.

I was just asking if anyone has used it and their opinion about it, i was asking for some previous experiences with this lens...
