moreton 0 #1 May 17, 2008 I have just received my Raynox HD-5050PRO lens to use with my HDR-CX7. I was surprised to find that there is a 37-37mm adpater ring. As the thread on the CX7 is 37mm do I need to use the thread adapter to get the correct focal distance? What's the point of this 37-37mm adapter? Thanks Ben Quote Share this post Link to post Share on other sites
PharmerPhil 0 #2 May 17, 2008 My guess (only that) is that they wanted to maintain the same distance to the lens whether you needed to adapt the threads to your camera or not. Can't imagine any other reason for including the adapter, so I have always used mine. Quote Share this post Link to post Share on other sites
moreton 0 #3 May 17, 2008 What's strange is that I also have purchased a Raynox 0.3 (HD-3032PRO) and despite the thread being the same 37mm, they do no include a 37-37 adapter. Quote Share this post Link to post Share on other sites
The111 1 #4 May 18, 2008 I think it is to prevent the back side of the lens (convex) from bottoming out on either the front of the camera lens or the "shutter" (lens cover)... it may or may not be necessary.www.WingsuitPhotos.com Quote Share this post Link to post Share on other sites

MAtt is correct, that's what the extension ring is for. It's not needed on most lenses. Quote Share this post Link to post Share on other sites
base_nz 0 #6 May 19, 2008 Should putting a 37-37 adapter on my .3 raynox ( which doesnt come with one... probably due to adequate clearance) affect the picture at all????.....And you thought Kiwis couldn't fly!!!! Quote Share this post Link to post Share on other sites
