I've done many Sigma dock calibrations, and this method you bring up is new to me. Sounds great. I will try it next time and hopefully save some time. Very clever.

I own the 5d4 and 1dx. I've owned three of the 1dx. Love them. But the 5d4 gives me better images most times. And it isn't like carrying around a cinder block. I re-bought a used 1dx because I ...

Birdshooter, they look great! The snake is especially sharp, and I noticed you went to f/8 on it. Did you find stopping down a tad gave you a big advantage?

Monky, nice to see you on again. I don't think that what you think is happening is happening. I just took my 5d4 and performed your protocol. What I found was that, indeed, the focus area shifted ...

It's the cheapest full frame 14mm f/1.8 ever made.

No, that image was not cropped.

Here is one at 800mm, shot on the 1dx2.

I don't recall where I read this, but I'd seen someone write that Tamron was a contract developer for the Batis line, so it wouldn't be terribly surprising if a certain amount of time had passed ...

I have found that some types of canon batteries are  very easily replaced by third-party batteries. But not the lpe6s. I have bought many different kinds of third-party LPE6  batteries and none of ...

No, it is pretty much a big pain. The Sigma dock takes many more measurements then your typical AFMA experience. I believe that this makes this adjustment more accurate across a greater set of ...

Sigma 50 Art is my favorite. I'd be happy to participate in a rendering test, where we get people to take the same shots side-by-side with the Canon 1.4 and 1.2. Rendering is to a great degree a ...

I like the DPP raw conversion, but the interface is so, so terrible, I never use it. Truly bad. My wish list for Lightroom: 1) fix that bug where the panels on the sides go black after a while 2) ...

I am really captivated by this lens. I find myself using it for completely inappropriate purposes, simply because I keep wanting to use it. Was doing flower photos a few hours ago up in the woods, ...

There might be a handful of lenses that are sharper and smoother than the new 35 L II. The Sigma 85; couple Zeiss lenses; the new Sigma 135 come to mind. Nothing near that focal length. I owned it ...

All rational choices. The one thing that seems weak in your new collection is having a fast prime. The 50 1.4 is fast, but is probably the worst in its class. I'd get the Tamron 45 VC or the Sigma ...

The netting in this picture allows the viewer to grasp the nature of the gradual fall off of focus at f/2.5 I keep expecting my honeymoon period to end with this lens, but it remains locked on my ...

After selling my 5D3, I had to put in another $1500 to get the 5D4. In retrospect, I'd have paid $1000 more if I had to. Big difference, definitely worth the cost. But had I needed to pay more than ...

Completely agree that the trekpack stuff is way, way overpriced. But I bought it, and now I don't regret it. The reason: the Pelican case is way, way overpriced, and I can fit about 20 percent ...

A quick read by an amateur restructuring observer: Aside from cost cutting, this has to do with...
1) putting sharper focus on ensuring R&D tech actually gets out into the market by allowing for...

It depends on the cost of the cheap ones. I bought a cheap set, and I found that one of the four tubes caused some very strange out of focus phenomenon to happen. I was quite surprised that ...
