I normally shoot shows with a 28 f2 which has worked great as I've started out but I have recently been looking to upgrade. I just shot a concert tonight with a Metabones IV and a Canon 16-35 f2.8. I had some issues with it and was not impressed but have only heard good things so I'm wondering if I may have done something wrong.  I updated the firmware. In some of my shots I had some weird horizontal lines popping up. Especially in the lighting/fog. Also, focusing was very difficult with MF....

Hi I have access to an Advanced VX tracking mount for the next 10 or so months and I also have a Sony A7X and Sigma 120-400mm Telephoto lens. What I would like to do is try and shoot some deep space objects. I know I will need an autoguider set up and I am not expecting any amazing results just yet, but before anything I want to be able to tackle some of the maths behind this. I would like to be able to calculate using this FOV calculator,  http://www.12dstring.me.uk/fovcalc.php approximately...

Hi all, (I posted this in the UW photography forum with no response) The last time I did UW photography was like 5 years ago, with a regular camera. Basically the deeper we go, the more the yellows, oranges and reds are filtered out. As a result, we use strobes to bring the color back into the photos.  Since our IR-modded cams are more sensitive to reds (or is it just H-alpha?) ,would it not seem likely that the sensor would be usable underwater? Of course with a strobe, for those nooks and...

Hi all, I use the camera in subject for my astrophotography almost exclusively because with the IR-filter removed, the sensor picks up a whole lot more red and on a regular A7S. And there're lots of nebulae and stuff that emit red wavelengths in deep space. The last time I dove (dived) was with a Panasonic TZ7 and the OEM housing 5 years, and more recently, I've noticed that Meikon is producing really affordable housings for a super-wide range of cams.  My question is on the use of an...

HI guys, I found this lens used: Sigma 19mm f/2.8 DN, E Mount. Will this work without vignetting on an A7S? I saw a few videos where there was vignetting but maybe they were using another mount? thanks PS. Should have mentioned this is strictly for VIDEO.

A filmmaker told me that you needed to pull the entire SD card contents in order for video editing software to be able to use the clips in full quality (whatever that means). Is this true?   I notice that each video file from my fs5 or a7s has an accompanying xml file, but there are also index and database files in other weird locations on the card. I can't find any official guideline for Sony or info about how video editing software might benefit from these additional files (and which ones)....

I have a canon LTM 50mm f1.4 which I want to put on my Sony A7s. Quite tricky finding decent adapters to go M39 to E mount so I wondered if I could use my Leitz ( Leica Made) M39 to Leica M and then add a Leica M to Sony E, or is this just too silly? Any recommendations for adapters M39 to A7s? With thanks.

Recently I got hold of this el-cheapo mount conversion adapter just for the purpose of using my Canon lenses on the A7S for astrophotography.  With both the 200mm f/2.8 L II and the 300mm f/4 L, there is severe vignetting in all 4 corners. Entering APS-C mode makes it perfect.  Does this vignetting happen in other adapters like the Fotodiox or MB? Roger
