A few pics and video from our recent Sea of Cortez trip on the Solmar V. Originally we were going to go to the Socorros, so I didn't have a macro lens along.
The Sony a7 is ground-breaking is a full-frame mirrorless camera, lots smaller and lighter than my D800 for sure. Better low-light and a host of programability. BUT lens offerings are pretty scarce. Hopefully by the end of the year this should be improved.
With some of the viz "challenging", I ended up shooting a fair amount of shallower available light. With the a7's low-light abilities it was easy to shoot up into the 2-3,000 ISOs without much degradation at all.
Using the manual focus Nikonos lens was a bit different, but it has such a long depth of field that I just stopped it down and only changed focus from CF/WA to WA as necessary. Using focus peaking it was easy to shoot when you saw the "reds" of their eyes! I also used the 28-70 and for a "kit" lens it isn't bad, with a close up diopter, I think it would work out well. I did shoot some moderate close ups and with the huge files, a little cropping came up with some pleasing images.
