Good Dioptric News For OM Users

[ruben]

What do you do if you do not shoot with the high end OM-3, OM-4 (T, Ti) cameras -all of them with built in dipters -and you need a correction diopter ?

Be it the OM1 or any other OM camera, as you may know all of them carry the same size viewfinder frame. Just that the last time an OM correction diopter have been seen is not even recorded in Langley red tape.

Fortunately for us, there is a big and healthy competitor, NIkon, which one of its diopter types does fit better than a glove, i,e, tight, on the OM viewfinder frames: they are know as "F-501".

Not only that, but Nikon diopters in general are the most common at eBay.

Cheers,
Ruben

PS:
A slight digital implication: do you understand why I don't want to fiddle ever again with Olympus, and have my doubts about departing from Canon in the digital field ?

Well, they may be rare, but I have an OM Eyecup 1 and a +2 Diopter posted in the classifieds now. See:

Thank you Lewis !
finally I will be able to tell my grandons that once upon a time an OM diopter was seen and recorded in nowhere else (of course !) than RFF !!!

Cheers,

and don't forget there was Olympus Eyecup 2, each with built in diopter glass. John

So, Ruben -- are you saying that Nikon diopters for the F-501 (Nikon 2020 in US) fit on the OM 2, 2N?

If so, do you happen to know whether the Nikon diopters are labeled in terms of their actual strength, or in the combined strength of the diopter and the VF?

May your strudel always satisfy.

John,

Do you have any +2 Eyecup 2's left?

 

[Pickett Wilson]

A Nikon +0 eyepiece is the equivalent of a +1. Nikon's are -1 without an added diopter.

Yes, positively, since all OM viewfinder window frames were manufactured of the same size. And even better, the F-501 diopter frames fit tighter than the loose original OM ones, who ever used them, like me, lost them on the field by dozens. But, unlike the Oly eyecup, the Nikon diopters are sold without the rubber sun shading eyecup.

If so, do you happen to know whether the Nikon diopters are labeled in terms of their actual strength, or in the combined strength of the diopter and the VF?.

Here you caught me in a foreign area. But Picket Wilson, in his below post seems to answer.

What I can contribute here is that the Nikon diopters in general are sold fairly cheap, and the cheapest eBay store for them is dscamera. Therefore all you have to do is to go to this store, look for diopter, and save the search for daily emails report.

Meaning that in case you order there a mistaken diopter, you will likely buy another one for penauts instead of start arguing, like an honourless folk like me would do

May your strudel always satisfy.

Amen

lol, Ruben, thanks again -- and to you, too Picket Wilson.

And if you want to buy them new, Adorama has the best prices and free shipping on them.

I can confirm the Nikon F-501 trick works - I just found such an eyepiece from a seller on eBay and it fits on my OM-2SP. It is snug - you have to wiggle it a bit to work in onto the existing eyepiece frame. The only downside to this workaround is it interferes with the opening of the film door, so you have to slide it up a millimeter or so when you want to open the door.

(I had been looking for years for the right Olympus eyepiece in the diopter strength I need to no avail.)

In much in the same way, diopter eyepieces for newer Canon cameras fit on the Pentax MX and other Pentax cameras of its generation. Grotesquely large and also blocks the film door, but much more widely available and cheaper than the original.
