Rokinon 35mm 1.4 vs Zeiss 35mm 1.4 Autofocus Test by David Vogt


Here is a quick video comparison of the autofocus systems of lenses at different price points. The Rokinon AF 35mm FE does a great job against the Sony 35mm Distagon while costing much less.

Download Sony a7rIII Manual Preliminary

This is the manual for the new Sony a7r III / mark 3 46mp full frame camera with touch screen. We think this is a preliminary copy since it does not match the menu of the cameras we played with at Photo Plus Expo. We still think it's enough to feed those waiting for their a7r III pre-orders.

Download the a7r iii manual via Dropbox.

So what comes in the box if you bought a body only a7r III?

Accessories included with Sony a7r III


So here is the discrepancy in the manual, under Shoot / Drive Mode, Px. Shift Multi Shoot is missing. I hope the next revision will have better detail on Pixel Shift shooting.



Here is the Shoot Mode / Drive 1 menu on a pre-production Sony a7r III showing the Pixel Shift option.




Pre-order your a7r III from Amazon and support this site.


In case the Dropbox link dies, here is the Google link for the a7r III owner's manual.



Sony a7r III Pixel Shift Multi Shooting Mode Impressions

Sony a7r III in Pixel Shift Mode



We had a chance to fondle the new Sony a7r mark III with the new pixel shift multi shooting mode. Pixel shift moves the sensor one pixel at a time to capture four frames. The four frames consist of the same image with a full red channel, two green channels, and one blue channel. The images must then be processed and combined in your pc via Sony Imaging Edge software.

Leica Thambar-M 90 on Sony A7 Cameras

Leica Thambar-M 90mm on Sony A7 by Kazuhiro ITOH
Leica reintroduced their Thambar 90 f/2.2 lens this week. The look it produces is very distinctive, dreamlike image. Posted here is a gallery of Leica Thambar 90 images taken with the Sony A7 cameras via lens adapter. The 1935 designed Leica Thambar-M 90 can also be used in autofocus mode using the Techart Pro LM-EA7 adapter with the newest generation of Sony A7 cameras.

From Leica: The new Thambar has almost entirely adopted the design of the original lens – featuring the same proportions, black paint finish and red and white aperture scales as its 1930s predecessor. The red scale applies when the center spot filter is in place, which diminishes the effective aperture of the lens – for example, from 2.2 to 2.3 when wide open. When working without the center spot filter, the white aperture scale is used. In order to retain its vintage appeal, the Thambar’s exterior has only been subtly adapted to reflect the pared-down character of c…

Kamlan 50mm f/1.1 E-mount Review by Kai

SainSonic Kamlan 50mm f/1.1 Review by Kai Wong


Here is Kai's review of the SainSonic Kamlan 50mm f/1.1 lens for Sony E-mount, a bokeh beast as Kai calls it. The lens covers your aps-c sensor found on the Sony a6500. Below you can see the image it creates on a full frame sensor. The aperture is clickless which is good for videography. We would keep it at f/1.1 so the lack of clicks wouldn't bother us. The price of the Kamlan 50mm f/1.1 is very appealing for such a fast lens. Buy an ND filter and keep it at f/1.1.



From the manufacturer, Sainsonic:
Large Aperture - Designed with high quality multi-coated optical glass. Exquisite body features amazing maximum aperture of F1.1, which creates fascinating background blur effect and sharper image quality. No worry about the low-light & night scene, just shoot and enjoy the safe and fast shutter speed.
