This is a first for me, using an old manual focus zoom. It's not small and I tried this on the Sone Nex-5n which isn't exactly big. I have to admit the whole rig is simply a little front heavy. I may try it on the Nex-7 if I have the time but I don't think it's going to work. The reason I haven't tried these zooms before is that they tend to big and heavy. Zooms of this period were not renowned for their image quality, it's just in recent time that zooms have improved considerably thought he help of computer aided design.
I also noticed that it lacks contrast somewhat and that in itself increases post processing time. It seemed quite sharp at times and other times not. I just couldn't nail it down to a focal length and aperture setting. Looking through the test images I see they do respond to some processing quite well and the colour is accurate.
More on this lens in the next few posts.
