G5 X circular edge softness -- is this normal?

I am currently evaluating a brand new G5 X and I am seeing results that I'm not particularly comfortable with especially when compared against an old PowerShot model I own, the G11. Would the G5 x's larger sensor size be the cause of the edge softness compared to the G11 which shows no such occurrence?

I am wondering what you're seeing here is perfectly normal for a compact with larger sensor size. It gets worse when I shoot in Macro mode at f/1.8 but that's entirely expected I guess (I have a 5D Mark II/III with 100mm f/2.8 Macro lens and aware of the extremely shallow DOF effect). Stopping down aperture to f/4, f/5.6 produced very marginal difference in regards to how close I was to the keyboard.

To compare to the G11 at f/2.8, try the G5X at f/4.5 or f/5 to normalize the depth of field relative to the sensor size.

It's normal. The sensor is much smaller on G11. Also note that the edges are further away from the camera than the center. Keep the camera in the same spot and angle, but tap focus at the corner instead of center, you will see the edges improve.

Stopping down should vastly improve the situation.

A bit of zoom can help in regards to corners. Try at 35+

Thank you for your responses and shooting tips! I did not expect a learning curve with 1" sensor coming from the G11 and 10 years of working with full frame EOS 5D bodies. With the G11 I could easily take a 1 cm macro shot and photo would turn out sharp. Now with the G5 X I don't see the point of having f/1.8 aperture and 5cm focusing distance when you're going to expect fuzzy images.

I'm sure you'll find some uses for f1.8-2.8, eg, evening and night time outdoors, indoor flashless, bokeh portraits...

For macro, if f4.0 or smaller aperture isn't giving you the bokeh you want, try moving back from the subject and zooming and sticking with f2.8.

Both f1.8 and "macro" mode have their benefits individually, but that doesn't necessarily mean it will work great to use them both together.

1" sensor, F 1,8 and distance 5 cm works very poorly

The picture is from a DOF calculator. F1,8 24mm wide distance 5 cm you only get a DOF of 1mm!!!! chard Daugaard

If you choose F11, it helps a bit, the DOF increases to 9 mm, still not much, but better. With F 1,8 nearly nothing is sharp. Sincerely Holger Daugaard

Re: G5 X circular edge softness -- is this normal?

Shocking! Some years back I naively wished that someday Canon would release a Powershot model with a full frame sensor from the 5D Mark III. I was only thinking about how great IQ would be back then, completely dismissing the issues I'm now seeing with a 1" sensor.

Re: G5 X circular edge softness -- is this normal?

Any sensor and lens combo is going to have it's limitations. It's all about learning to work around it. Is it really a problem to stop down to f4? Or back away from the subject and zoom in and shoot at f2.8? This camera IMO is the best all-arounder on the market, but physics doesn't allow you to be right up on a subject at the widest aperture and have sharp corners. That wouldn't make sense, and it's the recipe for bokeh; if it *weren't* that way, you would have crap bokeh when you wanted it.

Re: G5 X circular edge softness -- is this normal?

Yes it's a problem for what I use the camera for: hand-held food close-ups, and I think you can already picture the problems I am facing. It's easy for anyone to hold the camera at a distance and capture the entire plate or even the entire table but I take artistic close-ups of food and both the G11 and Note 5's sensors have been straightforward to shoot with.

Stopping down the G5 X to get acceptable sharpness across, I may end up with shutter speed I cannot reasonably hand hold to avoid camera shake. In which case, I may need to shop for a mini tripod to overcome that and we all know once the camera is mounted on a tripod, it's another story to get creative with angles etc.

For everything else, the G5 X makes a great all rounder. I also take pictures of my daughter using the 5D Mark III + 70-200mm when she competes in 400m track events. Looking forward to seeing how well the G5X Servo and continuous AF handle this.

Re: G5 X circular edge softness -- is this normal?

The nice thing is that hi-ISO is going to be far cleaner without heavy processing than the g11 or mobile. And you can handhold easily up to 1/13, if you've got very steady hands, 1/5. I don't think you'll have any issues at f4-f5.6, even in rather dim lighting.

Ever shoot a 150mm macro lens at f/2.8 at minimum focusing distance ? Most of your image will be out if focus. You need to read up on depth if field before making such ill informed statements.

I suggest you sell your G5 X and continue to use your phone for pics. Problem solved!

Yes, the G5 X is vastly superior to the G11 in every respect and Canon bringing back the vario-angle LCD is the very reason I waited years to finally find a worthy successor.

You seem to have gotten the idea that I've come here to give the G5 X a bad review. Quite the contrary I like the camera very much and nothing but praise for finally giving me a successor to the G11. The 1-inch sensor turned out to be a learning curve for me and I greatly appreciate the responses (before yours) that helped me understand the fuzziness isn't a defect.

As a matter of fact, I have shot original EF100mm f/2.8 and later the Hybrid IS version for a total of 10 years. It is comment from rpm40 that answered it for me "Both f1.8 and "macro" mode have their benefits individually, but that doesn't necessarily mean it will work great to use them both together." along with the DOF Calculator screenshots from Richard Daugaard that made sense right away.
