pulpo 0 Posted November 14, 2010 I purchased a Nikon D300 last October and I have been able to get underwater with my gear a few times in the last year. I'm using a Subal housing and have recently purchased a 2x TC to go with my 105 VR in hopes of practicing super macro. Does anyone use this setup, and if so, what length extension ring are you using? The TC is Kenko if that makes a difference. I purchased a used 40mm thinking that I had the right on. I am about 1/8" shy. Any help would be greatly appreciated.

Does anyone use this setup, and if so, what length extension ring are you using? The TC is Kenko if that makes a difference. I purchased a used 40mm thinking that I had the right on. I am about 1/8" shy. Like you, I use a D300 in a Subal Housing. In my case I used a 1.4x Kenko TC to go with the non-VR version of the 105. It seems to me, and this was a while ago, that I used either a 15" or 18" extension for the 1.4x TC. At that time, though, I didn't own the 105 VR port. If you are using the 2x TC with the 105 VR port, I am not sure of the exact extension you'll need. I would give Reef Photo a call. They are one of Wetpixel's sponsors and you should be able to click on a link to their site. They are extremely helpful and should get you an answer reasonably quickly. Although I've never used the 2x TC myself, I have heard that it can be difficult to use due to the razor thin depth of field. Be prepared to be patient when using this combo. The super macro shots, though, can often be spectacular for the very patient uw photographer. Hope that helps, Ellen Share this post Link to post Share on other sites
