A7ii PDAF with firmware
« on: November 19, 2015, 06:15:33 AM »
Yesterday after the release of he new firmware I met with a friend who owns the a7II and gave the camera for a test.

A7II +LA1+70-200G f2.8.

Before the update it was better to switch to manual focus or use the dedicate LA2/4.

After the update the above combination but only with LA1 adapter tested I can say you have almost a new camera.

-Autofocus speed is fast and accurate maybe equal to the E-mount lens. The only difference is that you loose the Lock on AF and the magnification when turning the focus ring.
-You have the option of AF area:
 
a)Wide all 179 af points
b)Spot focus
C)Flexible spot
D)No Zone available

The best one in my opinion it was flexible spot where you can change to Small/Medium & Large.

In Small area you get only one AF point from the 179 and in medium you get about 3 af points and in large you get about 9 af points.

Next week a friend of me will have the new A7RII with 24-70FE  and I will have a chance for a test and report :)

 I too have updated to firmware version 2.0. I only have A-mount lenses and the LA-EA3 and until now the best option was manual focussing as it was very slow. The camera now focusses quickly given they are non native lenses, 4-5 times quicker than before. I use the flexible spot af.
 It has transformed the camera from a slow manual camera to something which is much more useable all round with the A-mount lenses and no mirror. Uncompressed raw files are also rather large and not yet supported in LR. I have only had a short play around with the camera in the house and have more testing to do before i make my final judgement.

I own the A7 with the LA-EA4 and find the focusing to be as fast as the A77 & A850. Having tried my Minolta 200mm f2.8 G, Sony 50mm f1.4 and the Sony 70-300mm G SSM at various focal lengths, I find no appreciable focus speed differences. Having never tried the A7ii I am at a loss to understand why you think the A7 is slow? Perhaps it has something to do with the LA-EA1 & LA-EA3. Using the FE 28-70mm and the CZ 24-70 f4 the A7 is at least as fast as the Alphas. The A7 has wide, Center and Flexible spot. I use Flexible spot and DMF which together give me an ideal combination. To my knowledge, none of these settings affect the focus speed.

From what I have read the A7ii and the A7Rii have been improved (with the possible exception of focus speed as previously noted above). However the price of these upgraded cameras is ridiculous (somewhat due to the decrease in value of the Canadian $). I paid $800 CAD [$600 US, 400 GBP] for the near mint CZ 24-70 f4 from a friend and with the retail price at $1200 CAD, I feel I got a reasonable bargain. However the A7Rii is $4000 CAD retail. No bargain to be had there, especially after you add the sales tax. :|

Firmware revision 2.00 for the A7 claimed to increase the startup speed only. For the life of me I cannot discern any speed increase. Has anyone?

I will be very interested in your report on the A7RII Rex.  A landscape shooter friend of mine is moving from his Canon 5DMKIII to the A7RII when he can get hold of some Zeiss glass.  The lenses he wants are not available here yet.

 Charles, it is all down to the LA-EA1 & 3 as they have no mirror and rely solely on the cameras/ sensors contrast af to focus, switching to manual focus had to be done by the switch on the lens only and could not be done in camera menu. The LA-EA2 & 4 have a mirror and work like the slt cameras and have a built in contrast detect af due to the slt tech and also allow changing from AF to manual focus through the camera menu.

 Now with the update the A7II can utilise the on sensor Phase detect also which speeds things up considerably when using the more basic LA-EA3 adapter as it is working almost the same as the slt models and adapters but without the mirror.

Lenses with SSM and SAM will autofocus however older screw driven lenses will not with the LA-EA3 & 1.

Yes I see what you are on about now. Sony know how to make it complicated. Thanks for the reply Chris.

They certainly do, i had opted for the LA-EA3 as it was my intention to use it for landscape work with my A-mount lenses for the time being and i almost always focus manually anyway. The firmware update is a big bonus for me as its transformed the camera into a mini A99 (nearly) but with the bonus of no mirror.
