IPhone 6



Canon G7X



Molly my dog. It shows decent detail when really close.


Just wondering if some of the soft focus issue is actually depth of field related?? How close were you to these objects/dog?  There's a fair amount of close-up wide-angle nature to these photos... wondering if you were zoomed in and very close to your targets... in other words, nearing macro-focus end of the camera's lens? 

The focal plane on my compact cameras at close range is pretty narrow for similar distances - while I don't have the G1X II or G7X - their physical lenses and types of focusing systems are very similar - with live-view, it's hard to always tell where you're precisely focused - the green box isn't all that accurate as far as the exact location of the focal point... at least that's what I found on my G1X especially.  It takes very nice photos, but certainly isn't as easy to drive to sharp focus-ville as a DSLR, especially at close working distances. 

In my opinion - comparing them to an Iphone 6 (or just about any other cell phone/micro camera) isn't really a fair comparison mathematically - the aperture and physical lens size play a big role in those camera's abilities to render images.  While they may shoot very nice pictures and give you "35mm equivalent focal length comparisons", they have very small physical construction - the potential for their lens components to "miss" on focus is imperceivably microscopic in comparison to the internals of an external/interchangeable DSLR or even fixed compact camera lens.  Using your example photos - the Iphone photo clearly shows an unequal comparison in relative aperture - the bokeh is much less - indicating, at least to me, that it has a deeper depth of field at this given focal length.  It's going to show more objects in more detail/sharp focus in this example. 

A pretty good explanation here:  http://petapixel.com/2013/08/01/a-tour-of-the-equipment-found-in-modern-smartphone-cameras/


Now... I'll be the first to admit and support the argument that you should throw all of the "math/optical forumlae etc" out the window and shoot with the device(s) that get the images you want to see, unless you're one of those folks (like me sometimes) who really enjoy the math/physics part of equipment selection (including the math of sale price).  If your phone's camera does what you need it to do, do you need a $700 brick in your pocket?  Since getting back into SLR/DSLR cameras, I barely, if ever pick up my G1X... even on mountain-climbing/hiking adventures where the size/weight and all-in-one-nature of the G1X trumps the DSLR handily.  I will fully admit my galaxy phone's camera gets quite a bit of use on those adventures though too... if for no other reason than instant ability to share photos with internet friends while still on-site at the adventure.

Pull!... click... crap!  Lemme try it again...

I certainly understand what your saying but this camera just struggles too much to get sharp images. Since my wife will mostly use it then $700 is too much for a small travel camera. I will keep the search and look at the sony rx3 and g1x ii. I may consider the sony a6000 with the 20mm pancake for her.

How large a print will you be making at 300DPI?

A 12mpixel sensor will allow you to make a great print up to 10x16inches.  A 20mpixel sensor is good to 13x19inches.  If you know how to work the magic you can easily double the dimensions/quadruple the area of these prints.

I'm looking for a small(ish) traveling camera.  I will also buy a water-tight casing for scuba photography which is available for either camera.

Should I get the G1X Mark II or the new G7X.  I'm looking for the highest IQ and greatest ability for low light possible between these two cameras.  The size difference between them is not that important to me.

Here is my comparison of what is important:
G1X-II:  1.5" sensor @ 12 MP, optional EVF, hot boot for external flash, and nice grip
G7X: 1" sensor @ 20 MP, no possible EVF, no possible external flash and no grip

Again, I'm looking for the highest IQ and best low light pix since I'm used to what my 5D3 can produce.

Cheers
- It's the brain behind the eye behind the eyepiece that counts.
- The sharpest lens I own is a tripod.
- Equipment sitting there on the table, while amazing by any and all human measures, can't produce a brilliant piece of work without serious human intervention.
