Johnny B: Hi a7r ii owners and the curious,

I just downloaded some images of the studio test setup from the site so I could compare my 5DMKii to the a7Rii (downsampling the Sony to match my MKii size wise). I noticed color noise and moire in the Sony image that aren't visible in the Canon. I'm talking RAW - the jpegs don't display this.

The part of the test setup where I see this is in the engraving of the painter's studio. I'm figuring it has to do with the lack of an AA filter - I see the same noise/moire when looking at the D810 and 5DSR, but also the 5DS.

I think it's the only area in the whole test setup where I see this - I'm guessing it has to do with the crosshatching in the engraving. Due to positive comments about the camera it must not be a real-world issue. But I'd appreciate your comments if you've also observed this and either found it a non-issue or have a work-around to avoid/solve the issue when it appears. (sorry for my comment's length)

Replying to my own query: It looks like many cameras get this tiger stripe moiré pattern, even the Hasselblad (not the a6000, though). Curious.

Ken Luikart: The a6500 is a great little camera. I will take it on my next vacation. The image quality is no where near my 5Dsr or 7dMark II with my canon L or Sigma Arts lenses but I can get in in a big pocket!. The video is wonderful---ten times better than any of my other professional camera. It needs a pro quality E-mount 70-200 f2.8 and100-400 f5.6. Because of the size, putting a sharp but heavy G lenses takes a lot away from this nice little camera. It's blue tooth and Wi-Fy or not compatible with Apple products! This was a big disappointment. I was really surprised the first time I tried to send a photo form it to my iPhone to Facebook. I Had to take the photo over with my iPhone to publish a "right now" photo! Trying to find things in the menu is confusing compared to Canon and Nikon. The controls are just not intuitive. In spite of all my negative comments, this is a wonderful little camera that take great photos that you don't need to hire a Sherpa to carry!

Wow, that's the first I've heard/read about this limitation. I've been searching for a replacement to my 8 yr old 5DII and this feature is one I've been missing. But I wasn't aware of the iPhone limitation. Can someone confirm this please?

On article Remembering Fan Ho: 1931-2016 (35 comments in total)

I just happened upon news of Fan Ho's passing. Fan was a personal friend, a fascinating artist, and a strong supporter of his local, San José, CA art scene. He was so much fun to talk to and joke around with. His consistent, charming presence at Works/San José, a non-profit art space, provided a sense of continuity and community. As an older participant in the art scene he provided a sense of credibility and longevity to our activities. (Of course he's not alone in this.) You are missed by many, Fan. I'm sorry to see you go.

Why do people have a fascination with female-female sexuality?
