Back to the Sakar zoom lens, however briefly
After giving it a good work out in brilliant daylight, I am mostly impressed.
According to the meter on the F-2, there's a slightly better than 1 1/3 stop difference between 60 mm and 300 mm, which comes as no real great surprise.
Optical quality is much better than I had been expecting. I have experienced this before with Korean glass~ most notably the Banner line of scopes. There is a bit of bbl distortion at 60, but again, far less than expected. It fades quite nicely by 80 mm.
The hard infinity stop takes a bit of watching at 300. The lens turns a bit past actual infinity focus, and I have to watch the outer Fresnel field to make sure I'm properly focussed at distances. This is done a bit easier with the Fresnel field of the "K" screen in the F-3 as it's a bit brighter.
It's a nice lens, especially with the extra reach. I do think they could have made a much better lens by making it a straight 300 non-zoom telephoto. Good try on the do-all focal length attempt though. It actually works, if you don't mind the somewhat slow aperture speed.
Will try and get it up on the roof tomorrow at work- at sunset, if the weather holds. F-2 has a roll of 400 c-41 in it. Not too sure there's gonna be a rapid turn around on processing once it's shot. Lab is still open on this side of town, but is well under-staffed due to the current public health situation.

Doc Sharptail
