Hi, I'm fairly a beginner in underwater photography and till now have used the Sony A7iii with a Seafrogs housing with a 6" dome and the 16-35 f/2.8 GM lens. I've been quite happy with the setup. For my overwater images, I've upgraded to the Sony A1, and am looking again at the Seafrogs housing for that. Now I have two options that would suite my 16-35 GM (and they would also fit my on-land favourite - the 135 f/1.8 GM - at least physically). Here are my questions: 1. I have the option of a 6" dome that fits both lenses, or a long flat port that also fits both. Both ports have been tested with the 16-35GM to have no vignetting. The dome is acrylic, while the flat is double coated optical glass. Which would be better for me? 2. Is 135 a good focal length for underwater? It's not a macro lens, and the minimal focal distance is 70 cm. However, the 135 GM is amazing in low light, and often when shooting underwater, I do wish I could go narrower and capture some portraits. 3. How important is a strobe? I'm mostly a holiday diver, and have dived in the Caribbean, Bali, Philippines, etc. I don't see myself diving at night or in colder regions anytime soon. The seafrogs housings have a cold shoe on top to put a GoPro on. If I'm recording video while shooting stills, should I opt for a video light instead? Would the strobe ruin the video? Any recommendations on a strobe / video light to get started?
Due to system upgrade I'm selling this brute!... You know the brand - built like a tank - vacuum system faultless - simplicity and quality over finnicky plastic controls! Heinrich Weinkamp TTL converter (never used) and 2 nikonos bulkheads. Ports and house shows marks of wear (from about 400 dives) but no visible scratches on acryllic (Macro port has only 20 dives since last polish - Wide angle about the same). Minor post-production modification to vacuum indicator - makes it MUCH easier to see diodes. No defects to electronics or hardware. Reach out for more detailed pictures. Complete package 950 EUR plus postage - Paypal accepted.
I got this flat glass port, maybe for an underwater housing, with a bunch of second-hand Subal housing stuff on Ebay from a reseller. The port is 90 mm outer diameter, has no markings of any sort. It has three O-rings, two by the bayonet mount, and one on the outer ring surface. Your kind help in identifying it will be greatly appreciated.
