Some Aporia 24mm f/2 lens notes...
I've been out shooting with and enjoying this lens. For most shooting, I leave it fixed at f/5.6 .. particularly when I have the lens hood fitted as that makes it quite difficult to reach the aperture ring control even with a stylus and it's hard to see the aperture index. This nets pretty good sharpness all across the format by decreasing the curvature of field and deep DoF for ease of focusing.
For general shooting, leaving the aperture at f/5.6 has a side benefit: you can work very very quickly by zone focusing. You only need to remember two focus settings for the CL (APS-C format):
4.5m (15') = 2.24m (7.5') to infinity
2.5m (8') = 1.6m (5.25') to 5.67m (18.5')
The only problem is that the distance scale on the focusing ring, as my lens was delivered, is ridiculously way off the mark. I focused the camera on a target at 2.5m distance, the distance index shows between 2 and 1.5m; focused at 4.5m, the distance index is just touching 3m on the 2m side of the numeral. I wonder how far off the rangefinder cam is ... I'll have to check that sometime when I feel like using it on the M4-2.
In calibrating my focusing for scale focus work, I taped a target to the wall, set f/2, and focused the camera critically at both distances. The piece of the wall I taped it to has the pass through into my kitchen ... And what's interesting is that at f/2, the focus zone is shallow enough even at 15' focus distance to see things a mere 1' behind the critical plane soften up. I'm going to have to explore some wide open shooting with this lens too!
Anyway, now that I have it documented where these two distance settings line up on the focusing scale, I can use the settings above to do quick scale focus by zone.
Meanwhile, of course, I bought the lens to use on the CL: the TTL focusing is very accurate regardless what the distance scale calibration reads.
Having some fun, I snapped this shot this morning, rendered it on my desktop system to square, then handed it back to the iPhone and ShakeIt Photo app for the Polaroid SX-70 simulation framing and rendering look.
