The MS Optics 50mm 1.1 Sonnetar is very fast, noted on the description sheet as being f1.16. Now the MS Optics ISM 50mm 1.0 is available in M mount at only 178 grams. It is noted as f1.05 on the description. So it is only somewhat faster than the Sonnetar. If one already has a Sonnetar 50mm, not sure if they would be interested in this lens. With Gauss type lens it does not have the soonar qualities of the former, but apparently also not the tricky coma adjustment ring. 16 rounded aperture blades. Looks interesting though for digital or film, https://www.japancamerahunter.com/20...f-1-0-m-mount/
My love-hate affair with Miyazaki's lenses continues: I won't be buying the 50/1.0 (happy to be corrected, but CA seems unacceptable and oof rather ugly compared to the Sonnetar, at least on the sample pictures I have seen), but was sufficiently intrigued to order this 50/1.5 from Bellamy at JCH a few days ago. The lens arrived today and I made some preliminary tests (nothing worth posting here) to confirm that everything was OK. These lead me to making a couple of observations that may benefit anyone who might consider getting one. First: despite the fact that it's an M-mount lens, you really need a LV/EVF-enabled camera to use it. You could be forgiven for missing it from the cryptical online description, but the "Spherical Aberration adjustment ring" on the front of the lens has only one position where the RF and the sensor agree on where the focus is - and such position cannot be locked in. Well, I guess it could with tape or some mechanical modification, but it would somehow defeat the SA adjustment ring's purpose. In any event, LV/EVF is required IMO to be able to judge the effect of various SA adjustment settings. Second: the lens may well be the quirkiest one that Miyazaki has ever designed. Unlike the relatively subtle effect of the coma adjustment on some of his recent products, the SA adjustment has a pronounced impact on the final image, so that playing with combinations of aperture and SA adjustments offers virtually unlimited possibilities for experimenting. The downside is that it requires a more deliberate approach. This is not a set-it-and-shoot-away lens. I wouldn't use it for street work. Third: the lens seems to be well made, but at 1,200$, it's a b****y expensive toy. Buy only if you are prepared to invest the time and effort required - or if you have some cash available and like unusual (optical...) stuff. I guess I fall primarily in the second category, so not sure when I'll be able to post some pictures (assuming someone's interested), but I will.
