noone Posted July 24, 2019 Share Posted July 24, 2019 I was wondering when some company was going to do that. Some time ago, I found that some adapters have a small ledge in them and in one case, found it had a circular edge that almost exactly fit the glass from 43mm filters. I had been playing around with filters of that size to fit into the rear slot of my ancient Tamron 300 2.8 but to get it to fit, I had to file some of the metal edge off and then after realising it was about the same size as the space in one of my adapters, I filed the rest of the rim off (was just a cheap IR filter to start) and it fit very well with most lenses (some were a little long against the glass) as the depth was almost the same as the ledge depth as well as being the right size. I started looking for an apodization filter which became my holy grail. I stopped when my A7s camera died but have just got a cheap little Sony APSC camera so will start trying it again. If anyone knows of any (cheap- I know, I know) apodization filter, please let me know. I had found a few companies that did make them but not in the size I needed (some might have made me one but it would have been cheaper to buy one of the few lenses that have those filters built in and I can not afford those). Maybe this company might start doing that? I have posted about this before. This is the IR filter glass in the adapter and showing the bare ledge and a photo taken (as taken) using the filter behind my Canon 17mm TSE (a IR filter for my front filter holder would be huge and expensive for the lens otherwise).

noone Posted July 24, 2019 Share Posted July 24, 2019 Damn! Just emailed them and they have no plans for an Apodization filter. Oh well, my search continues. Quote Link to comment Share on other sites More sharing options...
colepat Posted July 24, 2019 Share Posted July 24, 2019 I love seeing this stuff. I've been waiting for some one to come up with a Canon EF – micro 4/3 variable ND adapter with electronics installed. That would be a game changer for me. A GH5 with "internal" ND. Quote Link to comment Share on other sites More sharing options...
thephoenix Posted July 25, 2019 Author Share Posted July 25, 2019 @BTM_Pix had something on paper but seems to be on hold at the moment Quote Link to comment Share on other sites More sharing options...
