AF-D & AF range test
« on: February 10, 2013, 07:18:58 PM »
After my trip to Africa and after updating to new firmware i finally had a chance today to test the a99 in AF-D mode with AF-Range.
Here i pointed camera in the sky set AF-range from 7 meters ~ near to infinity a just keep pressing the shutter.

Very nice indeed!

I wish people would stop posting nice images and especially how well the AF-D mode works LOL!

My resistance to not buy the A99 weakens daily :-)

Just to say if you are happy with a77 then i don't know what you will say about a99 AF module :)
As soon i saw the AF range control of the back of the camera before it was released i got crazy.This is the best innovation that a Camera maker made for a long time and i don't say this because i have Sony/Minolta equipment i Just say i am lucky that i didn't Jump ship in 2006 when i wanted to by my first digital after film.

Yes I love the A77 but not the low light performance? It the only real achilles heel of the camera!

yes I will lose the crop factor with the A99, but another camera body in the bag takes no weight or space up? You see how I trying to justify it to myself?

I will end up with the A99 that I am sure of? But I just keep hoping and waiting for a price cut LOL!

Rex I got sooooo excited at seeing and reading the commentary on the AF-D series I almost forgot to count the number of images in one post.  I say almost but I did count them. tsk tsk.

I updated my firmware on Saturday and now have AF-D on my workhorse 70-300G.  You have inspired me to go and practice.  Looks like it will be fantastic for the rators in flight displays.  I must admit to not reading the manual too closely as yet as I did not have a compatible lens until now.
What is you focus set to ?  Spot? centre weighted or does it not matter?

These are fantastic shots and I cannot wait to try it out....john

Here again i set the AF-range to a specific range keep pressing the shutter and as soon the motorbike come in the area the AF-D takes action.







As soon one motorbike jump in to the AF range the AF-D get in action. You can even smoke a cigarette or drink a beer :) the rest will be done by the a99 :)






This combination is a killer.Today it was a test, in a few week i will go for taking pictures :D

Sorry John i forgot also the rules ..... now i have change it.

On the flying/Jumping bikes i used AF-D ( all sensors 19+102) and set the AF-Range to a place (Sky) that the camera couldn't confirm autofocus with the range i specified for example 7m ~ almost infinity.
Because the camera cant confirm autofocus shutter is locked/blocked because i have(AF priority) keep pressing the shutter and as soon the AF points detect a subject in the range i specify they release the shutter.

In the second set because it was on a bend with trees i did the same but with the  left group and about 51 assist points. As soon the subject come in to the area  the left group with the assist point release the shutter.

PS.If you enable AF-D and for example left single Af-point/group the camera automatically select the surrounding assist points to help the selected main Af-points. Even if you choose the center group where is no coverage from assist, you will see occasionally that the left and right line assist will light up to help the center group
