You would actually leave both the lens IS and IBIS on. The lens' IS will stabilize pitch and yaw. IBIS will stabilize roll, x, and y.

In my limited experience (I only have tested a couple IS lenses), it depends on the lens and your adapter. For example, my 70-300L has issues with IBIS + IS (stabilization is just off, the images are not super sharp when using both). If I disable IBIS and rely on the Canon IS only, it resolves the issue.

At this point, we don't have a list to really refer to on when to use IS only or IBIS + IS, or IBIS only, etc.. so I choose to use Canon IS only when it's available (turning IBIS off). Everything else, I rely on IBIS, but I never mix the two.

Moved the luminance slider +20 in camera raw so yes, but pretty minimal. The files clean up nicely.

+20 only? Not bad for a 25,600.

DTBaan that night time water blur is BEAUTIFUL!!!

Gene I forgot one thing via flick mail, I did not use the timelapse app add-on for motion, I used the Syrp Genie.
And confirmation that the A7Rii (like the RX100iii) can use usb power in the field--why do I know this? Because I didn't plan on yesterdays timelapse and left the house withoutfully charge batteries BUT I did have a Patriot Fuel cell in the backpack and a usb cable, here was the rig-

I still think the 5DS R is still going to be an immensely valuable tool in my kit - even though the a7R II runs circles around it in several areas. One area where the a7R II may come up short is in the long exposure department.

http://www.fredmiranda​.com/forum/topic/13801​65

Snapsy is knowledgeable about the performance of various cameras, and he's thinking that the a7R II may be yet another poor performer in LE shooting. So, that's a bit of a disappointment, and tells me that I'll be using the 5DS R for LE work.

OTOH, it is still really early. We may see some better reviews/studies on the a7R II in LE. Even so, I am not wild about the fact that using LR noise reduction limits the raw output to 12-bit images.

David I read that whole page, you know I'm not a deep thinker in the science of photography, but the first thing I would have 'faulted' or at least wondered about is the 70-200 F4. It's a great lens but truth be known in that focal range there are sharper/faster lenses...could this have anything to do with the resolution of that highly shadowed area under the bridge they are examining?

Different user / similar complaint.

We do need to see more evidence; more reports before I will feel comfortable drawing any conclusions. But, these are concerning.

I did some LE with the a7S, which I figured would do great, but I hated the results. So, I have a growing suspicion that LE is something the a7 series isn't good at doing. There are several a7R II users here at POTN now, who can either prove or disprove the concerns with some LE test results of their own. I would love to see them.

It's things like this why I never want to be an early adopter (regardless of which brand). Not only are you paying a premium price, you're also often a beta tester.

Scanned the posts at FM and DPR about LENR issues. So an Achilles Heel appears with the Rii, bet it won't be the first.
For real astro imaging like I've done with my modded T2i and the 6D 5-10 minute exposures are desired/required on a tracking astro mount but astro photography only happens in my area during winter (when the clouds give way). So if it is a thermal issue causing the aberration that will be mitigated in the cold. If it is hot pixel mapping then a PlayMemories App could address that?
For typical night sky imaging i.e. Milky way. depending on lens no more than 30 sec. exposures are desired to prevent
trailing (coma is a lens dependent thing).
At this point I'll just sit back and gleen info as it trickles in but if I could get one clear night I'll find out for myself. I've got two spots each an hours drive that are semi-dark sky (rare here in the east).....chances here for a clear night probably 1 in a 1000.

Metabones has a list of when to use IBIS and IS on their website:

I can't comment on it though..my metabones III is running an old firmware update and doesn't play well with my 70-200 f2.8II right now. Need to send it in.

To be honest ive shot several 6 to 10 minutes exposures with my A7R and the noise at 100 was like when i would have used iso 400-800. i find that to be quite impressive

Totally. What noise is in the image is very evenly distributed and easy to clean up. The a7rII looks like it could be the ideal wedding, event, and portrait body.

Lol I have the tools...need to work on getting stuff booked again.

Is it just a case of keeping LENR switched on in camera and this issue is gone?

With the A7 I haven't been overly impressed with my ND110 exposures compared to those from the 5D2. I did have light leak issues though with the C/Y-E adapter. I tried some the weekend with the FE35 so will take a look at them later. This is also the only time I don't get on with the EVF as I keep mine set to auto off and it dies it while trying to compose.... I used to love setting the shouts up on DSLR without even switching the camera on!!

Yes you do. 36mp is so 2012

jk.

Phenomenal work as usual.

Here is a 30s exposure with the A7s at ISO 80. I do not know if the ISO80 will effect anything but yeah...
