Size matters in photography… most of the time

It is middle of the wedding season. Unfortunately, I have no time to write the blog, so I am going to give you two pictures with a comparison that will speak more than 1000 words. This can be the second part of my blog post regarding sensor size and aperture. For this comparison, I am using Canon G7 X. G7 X Mark II will give you identical results, in this case, and RX100 III, IV and V will give you just slightly worse results in terms of blurring the background. Versus probably most popular large sensor combination on planet Earth. APS-C sensor camera and 18-55mm f3.5-5.6 lens (by Canon in this case). Bear in mind that almost identical results you will get with slightly larger sensors from Nikon and Sony and even in you use 16-50mm kit lenses or another close in numbers 3.5 or 4 to 5.6 or 6.3 kit lenses.

Do not be surprised with results. Because DSLR cameras are meant to be used with any lens size. Also, the kit lens is full of air mostly to be cheap to make and to look adequate on this body. So APC-S camera is made to be versatile and the lens is made to not look funny on this body. On the other hand, G7 X is all about size efficiency.

But this is just one part of the story. Almost everything but size is on the side of DSLR. So if you have to chase kids around, DSLR will be a much better choice. G7 X is OK if your subjects are relatively stationary or if you have enough time to catch a good shot. DSLR is without question better tool.

  1. […] the world. With 100mm f2.8 it is better than any RX100 camera in this category. You have this and this blog posts on my website showing why G7 X is great for separating background. Even better than DSLR […]
