Serious G15 bugs
Jul 25, 2013

I bought this camera about a month before I went on a vacation. I tried it out on a variety of everyday situations, and it seemed to work reasonably well, although the viewfinder turned out to be even more worthless then mentioned in other reviews. The wide angle was less wide than my previous camera, but I thought it would be OK for most pictures. It wasn't until I started using it on my trip that I discovered that this camera has very serious flaws which are especially evident at long distance shots. When shooting at maximum wide angle, the LCD shows a wider field of view than the camera can actually photograph. Everything looks good on the LCD up to pressing the shutter button, but when the display comes up afterward, the result is cropped picture about 5-10% smaller on the LCD screen (and on the memory card) than was shown in the preview. If you try to take a near maximum width picture of a wide building, the sides get cut off. If you notice the cropping when the two second display comes up, in theory you can back up and take an overly large picture, but I found in many city situations the combination of the limited wide angle capability and this cropping made taking the picture of a moderately wide building or similar subject impossible. There was an even worse problem, however. Every so often I would take a carefully composed photo, and the the result would the a picture skewed up or down by about 20%, from what was shown in the viewfinder when I clicked the shutter. It turns out that you can carefully click the shutter, wait for the screen to go dark and the shutter sounds to complete, but apparently the camera has still not captured the image. I found I had to wait and hold the camera steady for a couple of seconds or so after the shutter click to make sure the picture registered properly. To be really safe, you need to wait for the preview to come up and look at it carefully. Needless to say these problems are a disaster if you are taking any sort of action scene. I've never had this sort of problem with any other digital camera. Add to this the fact that picture contrast and color is in general mediocre without significant Photoshopping makes me think I made an expensive mistake on this camera. Hopefully this can be fixed with a firmware upgrade.

So the G15 gives a Pre-corrected view on live view ? , that`s terrible, even the primative S90 didn`t do that and that used a barrelly lens too ....... the older Gs didn`t have so much distortion as the G15 so didn`t have the problem but you`d think if they could manage to get the old S90 to View with the finished FOV the G15 would (maybe that`s how they increased the speed ?) .

What is happening is that the camera is applying lens distortion correction in camera to your photos.  When you correct barrel distortion, which the lens has at wide angles, you lose the absolute outer edges in the distortion correction process.  PT lens does the same thing.

There are two fixes for this:  1)  You can shoot RAW and get exactly the image you captured on the sensor out of the camera for post processing.  And, 2)  You can frame somewhat larger knowing that there will be distortion correction if you want to shoot in jpg.

If you understand the camera and how to get the best out of it, it is still one of the best on the market.  I love mine.

That sounds very odd to me...  I've very recently started shooting both RAW+JPG since I just wanted to see if indeed I COULD see or get any difference..I usually just find it quite unnecessary to shoot RAW - certainly with the excellent results I can get from my G15.

Just inspected carefully the pairs of pics I shot today and I simply cannot see ANY difference at all between the two - NONE of them look different.
Maybe in some odd way I'm shooting different type pics.. but what you say SHOULD be a 'generality' if it is the case..it simply isn't so with mine.
I STILL love the G15 and in fact I think I  like it better than the G1X.. in spite of a few advantages in the latter.. fact is the PICS I get from the G15...SO easily in any circumstances .. are just so good.

Interesting.

At least at first sight, it looks like shutter lag, a time basically spent on focus hunting. (I wonder if you noticed the issue more often in low light situations?) On the other hand, I don't guess how come the shutter (synthetic) sounds completed prematurely. Gonna do some tests later.

I'd suggest you experiment either with half-pressing the shutter button and then shoot at the green light/AF beep or with locking focus earlier, during the process of composing (when it fits almost naturally, especially if you assign the "S" button to AF-lock).

I've seen no such problems with my G15 (aside from the inaccurate, but usable, OVF). Perhaps your G15 is defective?

Regarding colors, etc.: Have you customized MyColors in the Fn menu? There you can select a variety of things -- sharpness, contrast, saturation, etc. I've found that to be a very useful feature and the G15 to be a fine camera well suited to its purpose.

Hi Eric,

When you shoot in RAW + jpg, correctiions are not applied to the jpg.  It is simply the converted jpg with no corrections of any kind applied.  So the pair would look identical as you have seen.  But if you shoot jpg only and RAW only, then you can see the corrected difference.

Dale -

Thanks for that note - of course it explains WHY I see no difference...  but it does absolutely nothing to convince me that shooting RAW - at least for my kind of pics AND what may well be MY kind of general lighting conditions I invariably encounter in our general conditions - RAW gives me absolutely nothing (in almost all cases) better .. and takes probably 3 times as long to edit..compared to what is probably all of one minute or so (!!) for most of my JPG's I can get from my lovely G15 friend .. frankly I wish I'd never bought the G1X and would happily sell it for a half-decent price.   LOVE this G15 !!

I agree with you eric.  I feel the same way for the same reasons.  I was not trying to convince you to shoot RAW.  I was only trying to explain to the OP why he was seeing what he was seeing and what he could do about it.  But for me, I also shoot jpg most of the time and only occasionally shoot RAW if the shot is very important and I want to have more latitude for exposure and WB correction in post.  But for most of my G15 shooting I shoot jpg.

I did bump up the sharpness, contrast and color saturation one notch in custom colors, and backed down skin tone one notch so that skin color was not over-saturated.  I like the results I get with my camera set up this way for most things.

I don't often shoot at full wide either, prefering longer zoom for most shots, so I rarely run into the problem the OP was concerned about.  However, I have bumped my head on it from time to time and either switch to RAW +jpg for those shots that need it, or else over-frame so that it will turn out where I want it to be.

I own a G5, G6, G9, G12 and the G15.  Of all the G series, the G15 is the fastest and the best of the bunch IMHO.  I am quite fond of the little guy.  Of course for my more demanding stuff I also own a similar string of DSLR's.  Too much gear really, if such a thing is possible... LOL

Dale -

I've chopped all the early stuff as we don't want to go over that again...   but Oops!..I wasn't really saying or intending to say that you were trying to sway me onto RAW..it was just a bad way of putting it.. but I think it seems we both realize the merits of the G15 on JPG's anyway ...
I've used so many of this type now that I just setup a new one as I've always done for yonks and then (again as I've always said..)  it's getting a good composition that I believe makes the pic to a great extent..cameras are DUMB of course and if they are not SHOWN exactly what you want they just don't make the pic right.. 
But I must say... it IS so easy to have too much gear. Advances are fast nowadays and a new camera is often a better camera - so we are swayed towards it. Frankly I often look at some of my old pics and wonder WHY I ever changed...I'll swear a lot are as good as I get now - well..in some cases.. I've got a stack of "discarded" cameras..both P&S type (better ones..) and several good M4/3 ones that gave me a lot of pleasure.. alas most I now see being offered at what seem silly prices so I just hang on..a few go to younger generation in the family..most I just can't yet find a good home for.
I've even got my original G1 which on reflection I had a lovely time with - then jumped a BIG lot to the G7 (now with grand-daughter)..then a G9 (still got..waiting for said grand-daughter I suspect..)  ..then I never liked the bulkier ones after it until I got my hands by pure chance on the G15..and bought it within a week.. 
I sometimes think the expense of cameras is worse than the same on cars during a lifetime !! .. but for me I guess it just keeps my mind alive a bit longer .. and I don't need a lot now that I'd have spent on some years ago...
