Sony NEX-7: Damaging Contrast Bug

2013-05-21T00:00:00-08:00

In Guide to Mirrorless, I document a damaging contrast bug with the Sony NEX-7 that came and went while shooting a comparison. The bug is independent of lens and aperture and occurs with the latest firmware. Included are RawDigger histograms to show that the bug is independent of raw converter.

Autofocus with Sony NEX-7

I'm reading your posts about the Touit lenses with a lot of interest. Thanks for doing such an awesome job posting photos. You've for sure got the best NEX 7 plus Touit photos on the web at this time. I've got my 32/1.8 on order.

I'm noticing that you keep complaining about the autofocus accuracy of the NEX 7 and I'm wondering why you are using AF with totally stationary subjects when you've got one of the best manual focus machines ever made in your hand.

The EVF with magnified view and focus peaking is much more accurate than AF with any Nikon or Pentax DSLR I've ever had and one of the things I love about the NEX is being able to nail focus 90% + using the magnified view and focus peaking. Since you use Zeiss lenses on Canon and Nikon DSLRs, you're obviously used to MF, so try using it more with the NEX and I think you'll be very pleased.

PS - when taking photos of people, AF with Face Detection mode on my NEX 7 (I'm using my Sony 35/1.8 and 50/1.8) is fantastic.

DIGLLOYD: Over the years, I’ve written so extensively about how much I like an EVF and how critical focus accuracy is.

Suppose the 24-megapixel Sony NEX-7 were scaled up to full frame: it would become a 56-megapixel sensor at the same pixel density. So what would image quality look like? Pretty fantastic.
