A small and slippery suggestion:

I use a screw in diopter on my M9. I also use a 1.4x magnifier with the

appropriate lenses. This means I have to screw the diopter in and out

while busy shooting. The diopter is smaller in o.d. than both the magnifier

and the camera's outer metal "ring" at the viewfinder window. The diopter,

to make matters even worse, has a very smooth edge and I have a clumsy

time trying to switch it. It would be wonderful IF the diopter was just slightly

larger than the mounting with a gentle knurl that one could grip.

Anyone have a DIY solution for this? Thank you very much.

Use your thumb on the diopter to unscrew it; you'll have to clean the glass afterwards. It is one of the reasons I find magnifiers useless. (personal opinion!)

[Washington]

Yes indeed, this is exactly how I do it.... I have to.

But, for me, the magnifier is a necessity.

I haven't seem a diopter lens, but is there enough of the metal ring above the glass to put your own knurling on, like perhaps running a sharp needle file (used side on) around the edge of the ring?

 

Otherwise I think of the trick that can work to get filters off, press down hard on a mouse mat and twist. So maybe adapt it by making a little plate up from thin but rigid perspex sheet with a small section of bicycle inner tube (or other grippy rubber type stuff) glued on. Just press this up against the diopter and twist.

Sounds good. Actually I use the rubber sole of a shoe for removing stuck filters

I use a combination diopter adjuster and magnifier which I bought from what was then called "Megapearls" in Japan. Google and you will find the new name. Patent protection prohibited the sale in Germany and the US so I had to ask my son who lives elsewhere to give it to me as a Xmas present.

 

I have used the device for several years now and I am very satisfied with it. The main advantage to me is that the diopter correction is adjustable A most valuable feature for me as the correction I need changes (up an down) so that I need new glasses at least every two years.

 

Easy to screw on and off, but I generally "always" leave it on.

I think I may have seen something like this on eBay because there was a note

that it was patent protected in the USA and Germany. It sounds like just the

thing for my needs too. It's not so much that the diopter is stuck, it's just that

it's smaller then the "ring" it fits on and I can't get a grip on it. When you're

really busy and hurried it is problematic and frustrating.

I use a diopter correction lens and in my case it constantly get loose (even if I turn it hard), so I have the opposite problem, but no solution in this case I guess.

I might need a magnifier for use with my M9 and Summarit 75mm and came across the Phottix Etefore 1.25x on eBay. Does anyone have any experience or information on these?

[jaapv]

Hey! Thanks for that link. I got one for free from a shop that was clearing stock and I couldn't figure it out. Actually it is rather good and well made.

As mentioned in an above post - the Megaperls (not Megapearls...) is the way to go if you need a combined magnifier and diopter adjustment. I've been using their 1.15x magnifier for close to three years on an M8 and it is excellent.

 

New name of the company is Japan Exposures and here is the link:

 

japan exposures | films and more (formerly Megaperls Japan Webshop)

 

Best way to get around the trade mark issues is to state that you need the magnifier for Nikon binoculars .

 

Best,
