For the most of time I only use the 16 2.8 lens on my Sony mirrorless camera, sometimes I just wanna get a RX1R instead

Iya !

Was out for four days shooting long exposures. A7R+metabonesIII, mainly 24-70II. Just unbelievable results, this sensor is just amazing !

Now, here is a problem. I didn't pay much attention while shooting, I always crop square, but would like to know what it is exactly and how to avoid it. Look at the upper right corner :

http://www.nicolasgenette.com/temp/forums/leereflect.jpg


Happens with lee filter holder + big stopper + 0.9 or 0.6 filter.
Didn't tried without filters or so, seems to not happens when I avoid direct sun on filters with myself (but also have to hide wind !). I also have the standard Lee lens hood, but does nothing on this. I guess i is some sun light hitting filters from the back. Any insight about this ? Lee filters are also pretty new to me, so it may be a common behavior.

I was also surprised that batteries were really not a problem. Ok, I did shoot around 15 photos per day, but each between 1min30s to 4min ! My 1Ds2 batteries really didn't like such long exposure shots.

@KiboOst: could be the described issue with the light leak at long exposures. I remember to have seen photos where this sort of streak appeared in one of the corners. Simple solution: use a broader rubber band between adapter and camera mount to cover the fitting.

Ah, didn't though about this one !! As the metabones stay always on the A7R, I will check this and let you know after next photo trip like this.
Many thanks !

I ran a light leaking test and found nothing. First test is A7R + Metabones + Cap and second test is A7R + Metabones + EF lens + Lens Cap. Both were in 30s indoor and outdoor

It is described at exposures above 60 seconds under bright/sunny conditions in a real world scenario (I mean by not going to the extreme and shinging directly a bright glass fiber halide lamp next to the fitting).

Is that right? Who shoots for over 60 seconds in bright/sunny conditions? Even with a 10 stop ND filter it's hard to get to 30 seconds.

I have two Sony batteries and two Wasabi brand batteries for my A7R. The Sony batteries hold the charge longer especially at colder outside temperatures. Nevertheless, the Wasabi ones are a good deal and a good option just to have some spare batteries with you on a longer trip.
I avoid charging the Wasabi batteries with the Sony charger and vice-versa avoiding to charge the Sony batteries with the Wasabi charger. It looks like Sony batteries are charged a bit slower but better to keep the charge longer than the Wasabi batteries.


I am in CA, sunshine most the time...the two Wasabi batteries seem working fine. The normal/car chargers look cheap but they work fine as well. man, what do you expect more from 2 batteries and chargers for 26 bucks

I was with sunny glasses outside with exposures around 3min...
I previously tested ligh leaks with 30sec high iso lens cap etc and didn't see anything. Once more, real world situation is always different.
Will seal the lens mount and see what happens next week.

I don't think it's a light leak at the mount - this is light sneaking into the space between lens and filter. I have seen it happen if the filter is not inserted into Lee holder properly, or if there is a gap. I don't see it with Big Stopper since it has a foam seal but I have seen it with other filters - this exact look. So if you have 0.9 / 0.6, they don't seal , so light may get in between big stopper (which is also reflective) and one of these.

So what can be done ? Get som black pouch recovering front lens and filter holder ?
I always put big stopper in first (close to lens) holder, then another filter in next one (third one may be for lee lens hood).

hey sorry to seems dumb, but as A7R doesn'thave any mirror reflecting light to eye piece, we don't have to close/cover eye piece like on DSLRs, right ??

So the gap between BS and another filter needs to be closed - but it may not help much either as the light coming in will still slightly reflect off the surface of the stopper and then off the surface of the filter in front. I found these reflections to be hard to stop in this setup (for example I use stopper and a reverse grad at times, and I can get these effects), so I usually use the stopper by itself. If you need stronger effect, maybe you can try the new ND15 filter.
For now, see if you seal off the gap between the two filters if this will help (as I'm not sure if in your case its light coming into the gap, or light bouncing between the two filters. If the filter in front is square (like the polarizer) you can use black velcro strip to surround the gap - otherwise try to cover it with something temporarily (hand, cardboard) - you should see on the LCD if you get the flare.

You are right but who knows how EVF chamber constructed. Best is to cover the eye piece to make sure no light coming in anyway

I had experienced the very same light leak on long exposures (somewhere from 30" to 2, 3 minutes, day light). To my experiment, I determined it was at the mount between the Metabones and the A7R body - not the A7R fault. My friend at the shoot had the exact setup, metabones III and same lens, had no leak. So I would say, with precaution, it is a fault of some batch of Metabones. I covered using my darker t-shirt over the metabones/body mount and the problem went away.

Eye piece does not have to be covered in my experience.

Potentially there could be two gaps - as mentioned the one between camera and adapter (or lens) fitting, and also between adapter and attached lens. In both cases you can simply cover the space in between with a rubber band on each or use some cloth to cover both of them at once.

I've been reading plenty of threads on using L plates with Metabones III. It seems like Desmond L plate (with or without the Hejnar spacer) is the way to go. But ... I haven't found much on being able to use Metabones while A7R is fitted with the battery grip. It seems that once the grip is installed, there is virtually no clearance for Metabones foot, so are there options? I think RJ's adapter may work, since its foot can clear the grip. It just doesn't seem all that stable.
Also, any idea of someone made/machined an alternative foot for Metabones, to allow it to stick out from under the grip?

Have any A7R owner updated its new firmware "ILCE7RV102"? Do you see any improvement in IQ/AF/Menu? Thanks

I did. First update destroyed the EVF. Sent to Sony, after 3 weeks they called me and said necessary parts won't arrive for another 1.5 months, so they shipped me a new camera. It came with old firmware, but I updated it without any issues. Aside from quicker startup, I don't see much of a benefit.
