Thanks. Fame at last!!Hi There - it seems that Sony Alpha Rumours has it:
IBIS bug
David - I've asked Andrea to put your name in there - I didn't send it to him by the way.
All the best
I presume these are mounted using an adaptor that communicates electronically with the camera in which case all maybe well.I don't know if I have the issue or not but I seem to notice it working
on the Nikon 180 but really can't tell with the Canon FD 500mm.......
That is correct and I am hoping that when they issue a FW update to correct the issue found by David, they will offer 5 axis stabilization like Olympus (with assumed distances).is this correct?
According to this post, image stabilization for a third party lens, e.g. Leica M, would come from pitch, yaw, and roll stabilization from the camera body.
So, I now wonder how Olympus does it for the E-M5 and E-M1?
There one enters lens focal length for third party lenses but, of course, not focus distance information. I forgot once to update the focal length setting and IBIS overcorrected. That was easy to spot.
Thanks Vivek. That would be great!That is correct and I am hoping that when they issue a FW update correct the issue found by David, they will offer 5 axis stabilization like Olympus (with assumed distances).
No these are dumb adapters and manual lenses. I dial in the focalI presume these are mounted using an adaptor that communicates electronically with the camera in which case all maybe well.
That's very surprising.No these are dumb adapters and manual lenses. I dial in the focal
length but with the 500 I can hardly tell if any stabilization is happening.
John, Looking at your bird pictures, it is clear that your technique is perfect (solid tripod and the works). If that is the case, when there are no vibrations to deal with, why would the SS be active?No these are dumb adapters and manual lenses. I dial in the focal
length but with the 500 I can hardly tell if any stabilization is happening.
Yes you are right, I was too lazy to check and not recording exactly; here is one graph (there is another one including legacy glass on a third raw, but I wasn't able to find it)
Ah! This explains a lot. I'm a lazy beast and there are definitely times when I've done this. It might also explain Brian Smith's problem.Also keeps working if you don't turn the camera off at all. This of course goes ageing most Photographers way of changing a lens but at least unit a firmware fix it is a workaround
I don't think so but when you use the sensor cleaning option it really shakes it around unlike the previous models so I can only presume it uses the IBIS mechanism in some exaggerated way to shake it offEven better!
Does this camera do a sensor shake on startup? Or do you have to do it through the menus?
Thanks,
Matt
