One of the big feats of the new A7 line of cameras is SteadyShot. SteadyShot keeps your sensor stable while you take your picture with a shaky hand. It can be useful for video but also for stills, as you can (for subjects that do not move) shoot at very slow shutter speeds. This can prove useful for low light situations.
E.g. you’re on a vacation. It’s almost dark outside but you wish to shoot a certain monument while still staying on base ISO or not far from it. Well now, with SteadyShot, you can.
LOW LIGHT STABILIZATION TEST (HOW LOW CAN YOU GO?)
I’m was seeing the barbie dolls in Toy Story 2 when I wrote “How Low Can You Go?” lol. I think the barbies knew IBIS would come around and prepared me beforehand. Anyways, let’s get to the test. Before we begin, let me add that I have not taken the shots in burst shooting mode. These are single shots.
As you can see it is rather dark (and the quality of light is not good). When shot at 1/160 sec the ISO ramped up to a whopping 16000, which obviously is not what we’d want. Let’s go lower.
Using the reciprocal rule we know that we now have reached our limit at 1/60 sec using a 55mm lens. Starting now, the shots should start getting shaky.
(Reciprocal rule: You should be able to get non-blurry (motion blur!) results if you use a shutter speed that matches 1 divided by focal length. Example: When I shoot at 200mm without any body or lens stabilizer then I should choose a minimum shutter speed of 1/200).
As you can see we are still in the game. No motion blur. ISO is coming down to a much more digestible number.
Still shooting. Yawn. Too easy as it seems. But will it keep up with the next shot? Let’s see.
We are now shooting at a very good ISO 800, 1/8 sec and there’s still no motion blur, whaaat? NO shot had any motion blur in-between these shutter speeds. No fail shot at this point. Let’s move on.
The shot just before this one at 1/6 sec was blurry. But this one was clear again. We have reached our limit as all the shots after that one got motion blur in it. But look at that. We managed to get as low as 1/5 of a sec and to shoot at ISO 500 while using a single shot mode!
Now you tell me: How awesome is that?
(If you’ve got a shaky nature then just use a continuous shooting mode to get one keeper at those slow shutter speeds.)
When using continuous shooting I managed to get a shot as low as 0,5 sec at ISO 200. Check it out:
As you can see, SteadyShot (Or IBIS) is no joke and really works. Getting as low as 1/5 of a sec and even 0,5 sec using continuous shooting is some really tight stuff.
STEADYSHOT TEST IN VIDEO MODE
I’ve tested IBIS in video mode are here are the results:
