GH3 and GX-7 owners

I assume the GX-7 focuses faster? I have a GX-7 and a G2 and the 7 seems to completely outdo it focusing wise.

Is the GH3 focusing more like the G2 or did they improve it. I was thinking of one as a second camera to replace the G2.

Re: GH3 and GX-7 owners

My GH3 focuses very fast,  faster than my earlier GH models; can't say about the GX7 since I've very happy with the GH3 and the GX7 seems a tad small (I have some heavy lenses).

Perhaps the reviews here at DPR provide some insights -- under performance?

Re: GH3 and GX-7 owners

The GH3 and GX7 use the same focusing system, so yes, they're equally fast.

I have some heavy lenses, I've even used the GX-7 with a Sony 70-400 zoom. As with other cameras you hold most of the weight(the lens) with your left hand. It really doesn't matter how big the camera is.

Sony 70-400G is a fine lens. Too big for me even when I was shooting with a Sony body so I sold the lens first and the body a bit later.

Using left hand for lens is not practical in all situations.  Anyway, GX7 is too small for my hands. GH3 is just fine, and I like the spaciousness of its body. EM-1 I've not yet seen but does have a bigger grip than the EM-5.

You assume incorrectly. GH3 is as fast as GX7.

My GH3 focuses instantaneously with these lenses: 14-42 Mk II, 45 mm Macro, 75-200 mm.

You might want to read some of the umpteen reviews of the GH3.

Its focusing system has nothing to do with that of the much-earlier G2. Light-years difference.

The GH3 is great, and if you can get one for what they recently went for at one shop ($799), it would be a great deal. Weathersealed, incredible battery life, best video available in this market, etc. - it's certainly more than a backup or second body.

My "second body" is a GH2, but I am watching for a good deal on another GH3.

I got the impression from the DPR review of the gx7 that GH3 performance was faster overall. Not big diff likely; iike between A and B.

AFAIk GX7 focusses to -4 eV

GH3 does not i think, so it is not identical, at least not from that aspect and in the dark theoretically the GX7 could find focus where GH3 does not.

Re: GH3 and GX-7 owners

The GH3 focuses quickly, but part of it is the lens. It's best with lenses that support 240fps focusing (e.g. 12-35 and 35-100) but it's pretty good generally. Speed really won't be an issue.

My "second body" is a GH2, but I am watching for a good deal on another GH3.

I went from an GH2 to GH3 earlier this year and it is a very worthwhile upgrade even for a still-only shooter. And the price has come down: Appears to be just around $1000 vs. the $1300 I paid in March or so. Interestingly, the prices of the two f/2.8 zoom lenses seem to have increased since last Spring -- so I'm just as happy I already own them.

I had a GX7 on pre-order but canceled. My thinking was that the GH3 felt just right in my hands and that I really would use only one body (had a GX1 and never used it) and don't need IBIS since all my longer than 18mm lenses have OIS. At high ISOs the GX7 does better, but at 1600 my GH3 is fine -- and I very seldom shoot at ISOs even that high. I'm more likely to go for the EM-1 one of these days, since it has a usable grip and has received excellent reviews. But my earlier forays into Oly land have been painful, partly due to their menu system approach. So ... . Plus I've found no downsides in any of my uses to my GH3

Re: GH3 and GX-7 owners

I haven't compared them head to head, but I would guess that the GH3 has somewhat more processing power, and hence, may be able to focus a bit faster. But the difference is probably minor.

The GH3 significantly improves upon the GH2 in this respect. I would say that the GH3 was the first M4/3 camera to focus sufficiently well during video recording. Here is a head to head comparison between them which illustrates that:

Fredrik, checkout ephotozine results, the GX7 is faster than the GH3

http://www.ephotozine.com/article/panasonic-lumix-dmc-gh3-review-20489

and about the same as the em-5 and em-1, the real benefit to the GX7 though is it is faster and will be better than the Oly's in low light.

I read all the reviews I can, but it's rare if a reviewer compares a G2s focusing with the GX-7.

I see the GH3 is still pretty expensive so I will wait and see what Panasonic puts out to compete with the EM-1.

Yes my GX-7 is very good focusing in low light, unless my 60mm macro is on it.
