how much improved for action shots with 79 AF points in A77 II vs 19 in A77

and 15 cross type AF points in A77 II vs 11 cross type AF points in A77.

do anybody have water sports or any fast action images from both to compare. preferably using 2.8 lens

thanks for reading
 
Don't forget that the A77II also has an enhanced central focus point for lenses that are F/2.8 or faster, giving improved focus accuracy for large aperture lenses.

Other things to keep in mind other than focus points is the improved focus algorithms, the addition of more AF modes, and the ability to adjust the sensitivity of the AF to objects that move across the field of view when already locked onto a subject.

that's nice. this is what I am mainly looking as I am looking forward to use 100m f2.8 lens for some sports where I can be close so dont need long range, but i need 2.8 to manage low light shots

do you have sports shots taken with II version with a prime

I don't have any action/sports shots uploaded, at least none that will show you what you want. A single shot here or there would prove nothing other than to take that persons word for it. Even a sequence of shots wouldn't explain the whole story. The real test is to either try it yourself or possible watch a video of it in action. I believe Gary Fong has a demonstration of it somewhere on YouTube.

thks. I agree on that. few images wont convince me. canon 70d took me 3 months and 500 images before I like it :)

searching Gary Fong's video lead me to a good site, beside youtube

I believe the f2.8 feature has been around for a while. It was on the A-700. See first paragraph here:


I can't find anything about it on the original A-77, but it's probably included.

Lots better... its not just more AF points its a new focusing system with tracking Sony is putting in newer cameras they are calling it 4D focusing..

Sony recently updated the A77M2 page to link it to the 4D video that they released with the A5100 but A6000, A5100, A77 share the system.. with the only difference being the the A77 M2 has AF point set up using the SLT mirror for compatibility with all a-mount lenses.. where the e-mount wider coverage to sensor edge only works with defined Sony lenses the camera has info for (to deal with lens variations nearer the edge.

Be careful about getting hung up on single stats its about the system in focusing. In general I would not even worry about cross type AF spots for sports. They are nice but in reality they are there to give you better AF on vertical details like architecture that might be running up / down very parallel to the AF sensor orientation.. People, animals, landscape are not straight lines.. so in most cases will be fine with the vertically aligned sensors which catch horizontal details best. Cross type AF sensors are also a type of redundancy.. If you only have a dozen AF points having two in one location provides back up..

With the A77II there are so many AF points there is redundancy all over the place. And they cover a very large part of the frame.. compared to normal APS coverage.

Its how the Camera uses the sensors.. and part of what is going on is that Sony is using the main sensor to give smarts in selecting the AF points. Looking for shapes and colors the camera figures out which focus points belong to the object to be tracked.

In the A77s flexible spot system.. the camera will use groups of AF points to track an object.

There are two ways to select this tracked object. The camera can do it.. or you can use the center spot, press the joystick and the camera will then prioritize that object for tracking.

When I was shooting a kids cross country meet moving the camera up the line, if there was a kid with a t-shirt that was different like one red standing with larger groups of blue etc it would outline the kid head to toe (so it used the t-shirt to ID a unique object, but then realized the legs and head etc were also that kid. Even in packs of kids running it did a really good job of tracking a kid as they moved down the from the starting point.

But seriously its a lot better than A77m2. It's not about how many focus points you have but how its used. And A77m2 has all the software updates to use the new AF module well.

If it helps at all, there are some pictures on my Flickr with A77m2+Minolta 200mm/2.8 'HS' lens.

Don't Panic!.. these are just opinions... go take some pictures..
Does anyone have information about whether the tracking is also improved with screw-driven lenses?

These older lenses do generally not track as well as the newer lenses, maybe because of a certain amount of play between the focus motor of the camera and the AF gear... but has anybody seen some real improvement with screw-driven lenses on the A77 II compared to the A77? I'd be interested to know.

Agreed. The mk2 is just better all round including the in-camera JPEG engine.

It's not on the A77 nor the A99. It was last seen on the A700/A850/A900. The A77II is the first camera to have since that legendary trio.

Well the tracking and focusing is improved generally in that it locks faster and hunts less. But once you are locked on, the tracking focus itself depends on your screw driven lens. Some lenses like my Minolta 200mm 'HS' is descent (I can't say if its very good or not as I haven't had the time to test it). Other lenses like beercan are just inherently slow, not much you can do about that. But even then A77m2 can speed it up if you use the in-body AF limiter. -- Focus on what you have, not on what you don't. https://www.flickr.com/photos/nandbytes/

Great images in your gallery and of course, as we all know, the end results of an images is from Lens + camera with focus/tracking, so i may have a tough task to choose a lens :) But I would prefer to have 1 lens that would help me in low light, like 10mm f2.8 and get what is close to me rather than 300mm f5.6 and get stuck in cloudy days (most of this year except peak summer :)

It's best to have a lot of lenses for different situations. :-) I don't know how dark it gets on cloudy days where you are but in upstate NY there is plenty of light for slow lenses even when it's cloudy.

I don't shoot water sports. I've posted a whole bunch of fast action shots with the A77ii since I got mine on June 13th.

There is simply no comparison. The A77ii is the best APS-C sports cam on the market. The Canon 7D Mk2 may beat it in a few weeks but it's going to have to be mighty good - and you're going to have to be willing to spend a few hundred for the difference.

Great capture Gil. Did you do the manual settings on the fly, or were you just lucky having them preset?
