reikan focal pro lens calibration review

I have been in touch with Rich about the issue. I figured if you can AF using the shutter or liveview, Focal would still work, but I guess not.

I'm assuming liveview uses a different AF method that is still working.

The lens calibrates properly by itself, and the Canon EF 70-200mm f/2.8L IS II USM calibrates properly with the extender, but I think the problem is that with that 400mm combination, the lens actually reports to the body that it's in manual focus mode (as seen in the quick menu), EXCEPT in liveview, you can still get autofocus to work in liveview. My Canon EF 400mm f/4.0 DO IS USM lens and Canon EF 2x III Extender do not calibrate properly together, giving some weird error that nobody seems to know what it means. I am using a 7D with the latest firmware. I've since calibrated all of my lenses with the exception of one very specific combination. I purchased this software the last time it was mentioned on this site. While I think the 70-200 II plus TCs delivers usable images, I was less pleased with the 100-400 + TCs, it just doesn't stand up to them that well (and as Pat states, unless you nave a 1D III, 1Ds III, or 1D IV, you can't AF with the 100-400 + 1.4x anyway, fo FoCal wouldn't be of any use. So, you have to calibrate each lens and lens + TC combination separately, and each combo counts against your max of 20 stored adjustments.įWIW, the 1D X will go a step further and actually associate adjustments with the serial numbers of the lens and/or teleconverter - useful for studios with multiple copies of lenses that require differnet adjustments, since other cameras wouldn't know my 70-200mm f/2.8 IS II from Rick's copy of the lens, and so would apply the set adjustment to any lens of that type. Note that the two shots with the 7D are both at ISO 3200, which is pretty noisy, and the first shot was shot in heavy mist/drizzle (which is why I was using the 70-200+TC instead of the 100-400, since the latter is not weather sealed.īack to the point at hand, the EXIF for the middle shot, for example, shows the lens as 'EF70-200mm f/2.8L IS II USM +2.0x' and the focal length as 400mm.

5DII with 70-200mm f/2.8L IS II and 2x II.

7D with 70-200mm f/2.8L IS II and 2x II.

I think the 70-200mm f/2.8L IS II does pretty well with teleconverters. As Rick states, the camera is aware of the presence of the TC, and even records it in the EXIF data.
