With the 1.2" Mirrorless Dome Lens Port Extension from Ikelite, you can increase the length of their 5516.15 Dome Port with zoom control in order to accommodate the Olympus M.ZUIKO 12-40mm f/2.8 ED PRO lens. Use the optional 5509.28 zoom sleeve with this setup. Optional equipment may be required for compatibility. It's easy to remove the port from your underwater camera housing and attach the extension in its place. Once done, simply slide the port back on over the extension. See the Port Chart for the most complete, up-to-date compatibility information.

Q: 6. Does this support sony full frame lenses? It doesn't have sony lenses in the lens port chart.

A: Yes, the Ikelite DL 50mm Port Extension may be used with Sony lenses. However, it may be more advantageous for you to contact us with the specific lenses you plan to use rather than to see if a single port can be used with a large range of full-frame lenses. If you can either e-mail us at askbh@bhphoto.com or contact Ikelite directly at ikelite@ikelite.com with the brand/model of the Sony E-mount lens you wish to use, and we can assist you with the correct accessories compatible for use with your specific lens options.

Q: 7. Will this work with the Sony - FE 16-35mm F2.8 GM Wide-Angle Zoom? If not what specific extension do I need. I didn't find it on the chart. Please help me find.

A: This is the preferred dome for this lens. This Larger dome is best for split shots (half-in, half-out of the water). There is also a compact dome option which is better for traveling light. The BH #IK75344 • MFR #75344 linked here. https://bhpho.to/3068KtX. Either option would need these 2 extensions. B&H # IK75028 MFR # 75028 linked here https://bhpho.to/3bagtxj. And BH #IK75050 • MFR #75050 linked here. https://bhpho.to/3qezPWq. And this would be the Zoom Gear for it. BH #IK550916 • MFR #5509.16 linked here. https://bhpho.to/3032Tpk.
