Bokeh in Portraits: G7x vs S120?
1

Hi all,

That's what I mainly use my camera for, among other things. This is the most meaningful for me, and I don't mind spending for the best little thing I can slide in my pocket. Currently have the S120. Would absolutely appreciate comparative shots between the 2.

Yes, I have looked at almost every post with new G7x pics...

Thanks.

I don't think any comparative shots are necessary, the difference between the two is HUGE, about 3.5 stops difference in DOF control (background blur). Just look at the G7X portraits that are available on e.g. cameralabs.com to get an idea of portraits you can shoot with this camera; with the S120 background blur is almost zero, and most experienced portrait photographers think this is not a good thing.

  • at 100mm equiv. the S120 has an aperture of f/5.6 (FF equiv. f/23.5).
  • at 100mm equiv. the G7X has an aperture of f/2.8 (FF equiv.  f/7.6).

The S100 looks horrible compared to the G7X in this blog. Is IQ of the S100 really that bad compared to the G7X ?

Why did he shoot this at f8?

I will have a few s120 shots compared to g7x coming up. I don't have the g7x anymore and s120 was in the shop when I had it, but will try and match previous shots and conditions. It won't be perfect, especially settings wise but should give a halfway decent idea of IQ comparison with simple SOOC jpg shots. Should be up tomorrow afternoon Thai time.

No, this isn't representative at all. It could be that this specific S100 had a decentered lens (frequent problem with S100, causing one blurry corner/side) and the f/8 aperture doesn't help either. With a good S100 and aperture of f/4-f/5.6, I would expect the G7X to be slightly better at best (due to higher sensor resolution), but I would not be surprised if G7X is actually worse for corner sharpness at 24mm equiv. I'm judging from my experience with S110 which has the same lens as S100, with some more attention to QC

Don't know about the versus question, but here are some very wonderful portraits from the G7x, in an early stage writeup by one of the more trustworthy review sites.

Thanks everyone! Surprised to not have seen too many current s120 owners chiming in on the G7x...
