Jim Kasson is testing the Sony A7rIII Pixel Shift Mode: “big improvement”

Jim Kasson posted two articles (link one and link two) about the new Sony A7rIII Pixel Shift Mode. This is his conclusion so far:

Not only is the moire reduced by the stacking, the dynamic range is improved. This is not surprising given the fact that four times as many photons gave their lives making the four-shot stack than perished in any one shot. The stacked image is a big improvement. I think this is going to be a big win for anyone doing product shots of fabrics, or any other situation where the subject is still and false color is a problem.

Dpreview tested the Rokinon 50mm FE and says “The AF motor is very noisy, not unlike a distant submarine distress call”

Dpreview is testing the Rokinon 50mm FE lens but doesn’t seem to like it. The lens has some issues like the noise AF: “The AF motor is very noisy, not unlike a distant submarine distress call”. And the bad news continues:

The lens also has some issues with bokeh. Take a look at the onion rings in the out-of-focus highlights here, and if you search around the image above at 1:1, you’ll see slightly out-of-focus highlights having distracting holes in their center.
The takeaway: If you’re on a budget and want an FE 50mm F1.4 lens with autofocus, well, you don’t have a lot of options. Seeing as you can get some nice, usable images wide open, I wouldn’t steer you away from pulling the trigger on the Rokinon. But I would probably try to convince you to settle for F1.8 and save up for the Sonnar T* FE 55mm F1.8 ZA ($900) instead (quality-wise it is far superior to the Sony FE 50mm F1.8 – $200).

I do own the Zeiss 55mm FE and I absolutely love it. But I loaned it to a friend for a couple of weeks and it camera back with that noise AF. This is a “distant submarine distress call” :(

Sony A7rII: Shooting very high ISO and get clean images with (almost) no noise (by Dierk Topp)

This is a guest posy from Dierk Topp:

Shooting very high ISO and get clean images with (almost) no noise

A few days ago I saw a great tutorial about achieving high ISO images with low or almost no noise. I found it at lenswork.com, my favorite photo site with incredible picture series. The link to the tutorial follows at the end.

In astro photography this method seems to be very common, but using it for any hand held shooting is something different.

The main idea is, that by stacking multiple shots of exactly the same scene or object the different noise patterns of the images get combined and disappear. This can be very effective with high ISO and especially with small sensors. You set the camera on Hi continuous shooting and shoot a series of pictures. You will get a feeling for the amount of pictures depending of the exposure time it may take a while.

I got so exited, that I went out and started shooting the Christmas tree in front of our beautiful townhall with up to ISO 6.400. After learning the processing in PS I found, that I should try even higher ISO the next day. The problem that day was, that it was very windy and the tree and the flags where moving a lot.

Here is my first test shot
made with the Sony A7RII and the Sony 16-35mm Vario-Tessar T FE F4 ZA OSS hand held 1/20 sec. at ISO 6.400, stacked from 12 images

noise suppression with stacked images
if you don’t have or can use a tripod shoot some images (better more than 4) with high ISO hand held
load them into CS as layers
edit: Auto-Allign Layers
layers: convert to smart objects
layers: Smart Objects – Stack mode – Mean
and try to find the noise :-)

Sony A7rIII + Nikon 400mm autofocus test

Bernd Smid from our A7rIII group tested the [shoplink 65175 ebay]Nikon 400mm f/3.5[/shoplink] autofocus performance using the [shoplink 65176]Techard adapter[/shoplink]:

And here is an autotofocus test with the Canon 85mm:

Kai: “Sony RX0 vs GoPro Hero 6 – The GoPro Killer?”

Kai:Sony’s latest water-resistant, shock-resistant camera looks set to be tough competition for the GoPro Hero 6 with its bigger 1″ sensor and S-Log2 but can it outdo the most popular action camera around?

 

And here is the RX0 presentation video from Sony Europe:

First video showing INCREDIBLE tethering speeds of the a7RIII

Evan sent me his latest video showing INCREDIBLE tethering speeds of the a7RIII:

Shooting tethered with the Sony a7RIII over USB-C to a Microsoft Surface Book 2, using Profoto B1 lights, I test the tether speed of single shot for the first part of the shoot and then burst speed in the second part.
