Panasonic GX7 Owner assessment - Part 6 - adapted lenses, manual focusing and focus peaking

Yesterday I took some pictures with the three Nikon fit lenses pictured above attached to my GX7 via my Metabones Speed Booster. 

This 'fruit shoot' turned out very well. Using the focus peaking and the IBIS in the GX7 the whole exercise was easy and produced successful results. The peaking worked very well for the manual focusing and the IBIS allowed me between 1-2 stops in terms of higher shutter speeds and narrow apertures than I would normally have used. Everything was hand-held. 

The camera also handles these lenses very well. They are somewhat bigger and / or heavier than the m4/3 lenses I have but because the GX7 is not a 'micro' camera, none of these lenses felt out of place or seriously unbalanced the camera. As I've written many times before, I dislike small light lenses anyway. They just don't work for me when the camera is up to my eye. I'm so used to 'cradling' lenses with my left hand and have developed a very stable hand held position which allows me to use the shutter speeds and apertures I want. With the speed booster I'm getting an extra stop of light anyway so I was able to use ISO 125 for the majority of these shots.

Unfortunately the IBIS doesn't work for video, which is where it would be really useful. I tried some footage with the Voigtlander 20mm but it was too jerky to publish. A shame really, since the GX7 looks like the only camera that's going to have IBIS at the moment as the GH4 doesn't include it. 

The above files were also nicely sharp with a bit more 'bite' than what my native AF lenses produce, so you will probably realise that means they are impressively sharp. For my next trip out with the GX7 I'm planning to take a couple of the Nikons out to see how they perform for landscape / location work, but I'm certainly not anticipating any problems. 

Finally, there is an odd story circulating about the lack of focus peaking in the GH3 and OM-D E-M5, both of which apparently use the same Sony sensor. That story asserts that Sony wouldn't let Olympus (and I guess Panasonic as well) have focus peaking with their sensor!! Protecting their NEX sales I guess. It does make sense of some carefully worded Panasonic comments about the lack of focus peaking in the GH3 when they said 'It (focus peaking) wasn't possible with this (the GH3) sensor' These comments were phrased in such a way that didn't indicate that peaking wasn't technically possible and I guess we can now surmise why. It has also emerged that the E-M1, which does have focus peaking, has a Panasonic sensor, as does the GX7 and presumably the GH4, which again both have peaking. I would imagine that all three cameras use the same basic sensor unit. Just a thought but the latest business figures (if they are to be trusted and actually mean anything) seem to indicate both Panasonic and Olympus recovering their position somewhat but Sony having to make some serious cuts. Some might say, serves them right for being petty and mean!!
