Super Members Mattias Burling Posted February 23, 2017 Author Super Members Share Posted February 23, 2017 Since I can't edit my original post the images etc get split up here and there and mixed with the disussions (which are great, thats why I post here). But if one wants to view it in one single go there is pretty much identical content in an article on my site www.gunpowdervideo.com. An Update - Is it sharp enough? Im still early in the process of reviewing and I haven’t had as much time as I would have wanted to. But I have made some sharpness tests In my opinion, sharpness comes pretty far down the list on what makes a particular lens great. All Im interested in is if its “sharp enough” when using the old lenses and adapter in front of my 20mp Sony sensor. The short answer is “yes”. The Test The test isn’t the most scientific in the world. I just shot pictures of a book, hand held, using three different lenses. I decided to fill the frame more or less equal even though that made the two competitors able to get much closer to the subject. Even still, its sharp enough to my eye. The lenses where: The Mamiya 80mm f4 Macro + Kipon Baveyes Adapter The Minolta Rokkor 50mm f1.7 (also vintage) The Zeiss FE 35mm f2.8 (as modern as it gets) All where shot using the same settings at f8. The focus may drift a little but Im sure you can work it out by clicking and peeping the pictures. Here are the results! First we have the Mamiya 80mm f4 + Baveyes Adapter @ f8. Camera profile is "standard". Next we have the good old Minolta Rokkor 50mm f1.7 with a dumb adapter. Lastly we have my brand new FE 35mm f2.8 Zeiss lens. Its a very nice lens to have if you have a Sony A7. Great for street with its small size and workable focus scale on the display. It can have loads of aberration but other than that its great. And razor sharp. I don’t know what you think but I think it looks ok. There is a tiny bit of aberration around the square on right page from the modern Zeiss. Other than that I can’t really pick out any major fault in any of them. I think its safe to say that the Kipon Baveyes doesn’t have any major impact on sharpness. Which is nice and lets us instead focus on the good things, like for example the bokeh. These are from this mornings walk with Gunpowder. This one is straight from camera. This one is a bit graded. Here we see a tendency of another divider between people, swirly bokeh. Which I always like. I havent noticed any weird flaring so far. This was without a hood. Even at f4 the dof is pretty thin. Cant wait to test my 80mm f1.9! Luckily the Red peaking shows up nicely. Then Gunpowder got bored so we will leave it at that for now. Plenty more to come, more lenses and of course video. My lenses btw are 80mm f4 Macro, 80mm f1.9, 150mm f3.5, 45mm f2.8 and waiting on a Zeiss 80mm f2.8 + Penatcon 6 to M645 adapter. sudopera 1 Quote Link to comment Share on other sites More sharing options...
