It's great for landscapes and timelapse, which is where most of my shooting is done. I guess the a9 is where they want you to be at for true silent shooting and action though
I have a sequence of 13 photos of a very large dog as it swims across a lake and then leaps into action. It was taken with an A7R3 using center + expanding and shot at 8fps in Hi mode. Shutter speed I think is 1/2500.
The photos while the dog is swimming towards me are relatively sharp, though not perfectly so. At 1500 - 2000 long edge resolutions, I think they're clear enough. However, as the dog moves into rapid action and splashes water around, the AF system gets confused, and sometimes focuses on the water droplets instead of the dog!
Now, I know that I could have selected one of the "lock on the subject" modes, but I hate doing this, because it basically screws me over with quickly taking a picture of something else interesting that pops up. Plus, being used to tracking subjects with center point AF, I'm quite comfortable with keeping camera pointed where the subject is.
Out of the 13 shots, 5 are pre-action and fine. Of the remaining 8, only 3 are sharp enough to share; the rest are either just out of focus, or, the camera is focusing on the water droplets in the air. Perhaps I'll post them up so that others can see.
Isaacheus said:On the af point, I think part of the trouble is that it tries to focus with the lens stopped down, rather than opening the aperture up to get focus first, at least with one of the exposure simulations on: turning it off means that it will focus wide open and then stop down to the wanted aperture on shooting. Whether this is useful to you, or even the issue with focus and strobes, I'm not sure. All I can remember is that it's one of the settings I leave on, as I don't typically use strobes/flash.
I'm sure you mean Live View/Setting Effect On/Off. It does not seem to improve things, but frankly, the camera is unusable with Effect On (WYSIWYG) when you're using flash, because if you're correctly exposed to see stuff, the flash will just wash everythign out. If you have it configured for the flash, you won't see anything at all through the VF
Setting Effect to OFF, which make the VF always bright, does not appear to help.
Isaacheus said:The weather sealing at the bottom seems to be the issue yeah; I'm normally on a tripod, so not such an issue there hopefully. Looking for a good cover (for both the sony and Canon) to minimise the risk overall. Can't really justify a 5dmk4 or 1dx2 just for the sake of a cover vs weather sealing
I've always wondered about the crevices on battery grips and sealing, interested to know if anyone has had any issues with Canon ones?
The crevices on the battery grips and base have no impact on a canon. I think they exist to help grip the tripod plate to the base.
TBH, the weather sealing isn't a huge deal for me, because I don't shoot very often when it's raining, certainly not more than if it's a little drizzle. But still, I'd much rather have a camera that's weather sealed than not. Sometimes a little water or moisture is just unavoidable.
By the way, here's one of the sharper images of the dog.
Nice shot of the dog.
Pity you've had a bit of trouble with the af though - I assume you've been using native glass if you're shooting at 8 fps too.
I haven't played around with the lock on af yet for the same reason you have.
And I think you're right about the view finder effect setting, I would have hoped that would help the situation but looks like it's an area where it could be improved.
