p.1 #6 · 7D AF-MA Firmware 2.x with Reikan Focal SW | |
My experience with the Pro version and firmware 2 has been terrible.
With the earlier firmware, I was able to get consistent and repeatable MA results with my 70-200II and 100-400.
The 70-200 had been -3 at 70mm, -5 at 135mm, and -4 at 200mm.
The 100-400 was -5 at 100mm, -3 at 200mm, -1 and 300mm, and 4 at 400mm
After the upgrade to FW2, I got these results:
70-200: -14 at 70mm. -14 at 135mm, and -10 at 200mm. I repeated, and got -10, -9, and -11, respectively
100-400: -13 at 100mm, -2 at 200mm, 2 at 300mm, 5 at 400mm.
The weird part is the FoCal reports show that the target was sharpest at those new MA settings. But when I disconnected the camera from FoCal and the laptop, and shot the target handheld, it was obvious the old settings were much better.
Then I tried my 24-105, which I had not previously MA'd with FoCal. It came up with -10 at 105mm, but it couldn't MA 24mm. The image was completely blurred, and it didn't matter if I was at -20, 0, or +20. Even disconnecting the camera there was no way to get 24mm to come to focus. I thought the lens was going to have to go in for service.
I went back to play around with one of the other zooms, then when I put the 24-105 back on, the lens seemed to have reset. I could focus 24mm. Then I tried -10 at 105mm, and once again it was clearly a bad setting. The lens is much better at 0 MA.
I also frequently got errors that the software couldn't communicate with the camera, and I had to restart FoCal several times. This seemed to happen most with the 70-200.
So I'm not sure what to do. I haven't had time to try again. I'm just using the lenses at the MA settings I got with the old firmware, and everything seems fine.
If you update to FW2, I'll be really interested in seeing how well FoCal works for you.
