A55 User reports: 10fps in action + battery life report

We have some interesting updates from the folks doing real-life tests on the new A33/A55 cameras.

12 continuous-frame series with AF at 10fps:

2478 frames + 10min video till the battery level indicated 60%. Then 700 frames with 300/2.8G to get the battery to 0%.

Are you saying to clocked the maximum speed at 12fps?

Nice examples.

No, I'm sorry. It's a 12-frame series shot at 10fps.
My mistake.

3000 frames with a single charge?
there is clearly an error.
it's impossible.

Not impossible. The battery was after several recharges so closer to its max capacity.

No problem, still an interesting report!

Re: A55 User reports: 10fps in action + battery life report

Did it have any backfocus problems as described in dpreview review when shooting in AF-C? They say the AF system is not quite getting it right...

Impressive pictures!!

Re: A55 User reports: 10fps in action + battery life report

Well, the spec is for 300-400 shots/battery. If it was this good, why wouldn't Sony spec it higher?

Re: A55 User reports: 10fps in action + battery life report

Most power is cosumable by continuous live view (same as other main sensor LV DSLR).

The test here is done by keeping continous shooting @ 10 fps, thus the time cost by LV is minimal.

Any action series where the subject is changing distance to the camera?

Re: A55 User reports: 10fps in action + battery life report

3000 frames?

not even a d3s canon 1 battery that is big capacity battery can have this performance...

dpreview states 300 frame and some video....here we talks about 3000 frames plus 10 minutes video with gps attached...IMPOSSIBLE believe me it's clearly an error

Battery performance

Well, as a matter of fact they do - and then some. I have shot over 5000 images over two days on one charge with the D3 without even fully emptying it, and others have shot more then that.

It all depends on what and how you shoot - and on the battery size (just to addf the obvious).

If you shoot without stabilization, and only jpg, that could be very possible.

What drains power in a modern camera is first and foremost sensor readout and image processing - that is the big one. And the faster you do it, the more power it consumes. Depending in implementation, the next biggest culprit often is image stabilization. Also autofocus can drain alot of power, but this is very lens dependant, and can vary considerably depending on lens design and its focusing speed. The actual physical lcd display on the back is in itself is actually much less of a culprit then most people tend to think. But live view and video involves a lot of continous readout and processing which makes displaying a (main sensor based) live view/EVF a battery eater. This is btw another clever thing about the original Sony Live view inplementation, the small live view sensor uses a lot less power then main sensor Live view does.

But in short, if you shoot jpg images only, and preferrably small ones at that, do not use stabilization, you can get amazing amounts of images from a single battery.

Do the settings lock on the first image in a 10fps burst?

If it maintains focus on a moving subject it would be cool.

Re: A55 User reports: 10fps in action + battery life report

i agree with jonny i dont see why the spec would say 3 hundred and something pics a charge and your saying you got over two thousand pics ?

Re: A55 User reports: 10fps in action + battery life report

The 3000 images is after adjusting the camera settings (and the way you use the camera) to conserve as much battery power as possible.

In normal use, Sony estimates 350-450 images per charge. The key distinction there is 'in normal use'. Sony can't go telling people they'll get 3000 photos on a single charge when that's only in special circumstances. Otherwise those people will expect their 3000 photos in normal circumstances.. and be mad when they only get a 10th of that.

As someone else has already explained, the 3000 photos were taken without IS on and all in 10fps. So in reality it's only 300 photos worth of camera time, which is well within the battery's capabilities.

Re: A55 User reports: 10fps in action + battery life report

It definitely should be possible.

Ihave on numerous occasions done about 1200-1500 shots with one battery both with A700 and A900. The trick here is as some have written using jpg only and shooting fast. The "normal" shooting when you are recomposing, refocusing, reviewing etc a lot consume batteries way more than just fast shooting..

I normally get 1200 to 1500 RAW frames per battery charge on the a900.

Of course that is shooting pretty fast, very little chimping and with a fast card.
Fast cards, I think, they help saving battery life.
