I'm not surprised that this is a brand new thread, though a little saddened that more people don't own this lens. (If there is a thread somewhere I apologize, I couldn't find it) Ive had it for a little over a year and I can't say I have every shot with a better 50mm legacy lens. I purchased this lens on a "roll of the dice" best offer on ebay for about $650. I know its steep for a lens of this age but I couldn't be happier with it. I had tested a few 50mm on the A7 before this one including the Nokton 50mm 1.1, the Rokkor 50mm 1.4, Sony FE 55 1.8 and the FD 50mm 1.4. Each of those lenses are fabulous in their own right but this one just appealed to me so much it probably will never leave my bag. If I was to double down with another 50mm it would either be the FE 55 or the new Loxia 50 f/2. Though I would lean toward the FE to finally have an AF lens for my Sony rig ha! A few people have asked if I ever used the Canon FL or FD 55 1.2 and alas, I have not. Though either of those would have been the next lens I would have tested if it wasn't for the 'deal' I got on this one. As far as I can tell looking closely at samples from the FD 55, its probably this lens' closest cousin. The 2 render very similarly albeit with different FL. I think the biggest difference would be in the bokeh. This lens is noticeably smoother then the both those lenses, where those lens exhibit slightly more nervous OOF areas in my opinion. Also the FL is an 'older' lens so finding one in good condition may take some doing. The FD 55 is hard to find in the US as most listings I have every seen are from Japan or HK. Probably the biggest reason why this lens is so rare is both of those lenses are about 1/3 the price of this lens these days, if not more, so I can see why most would opt out. As far as capability, this lens is absolutely usable wide open on the A7 with very little CA or bloom which is surprising. Most of the shots below are shot wide open with the exception of the coral rock and my kids. My kids were at f2 the coral rock probably at about 5.6 or so. The focus ring is buttery smooth and has just the right amount of throw to get critical focus but isn't belaboring going from near to far quickly. Below are a few of my favorites with this lens.
