Nature walk yesterday to try and blow off some steam…
The GF670 lends itself well to just such an adventure; which is really why I decided to get back into it in the first place.
(Well that, and the screamin’ deal…)
Anyhoo, I have exhaustively come to the conclusion that at f/3.5, it is probably not pin-sharp.
You really have to stop down to f/4 to get reliable sharpness, and I don’t think it is just missed focus.
(…Or for that matter, moving children).
These were shot on Portra 400 at ISO 1600, and developed for 5:20 on new chemicals.
An easy two-stop push.
As a result: I am further purplexed.
They are much more grainy than the last ridiculous push, which really has me trying to figure out why.
