I was hoping to use one of these on both Contax and Yashica bodies, but I'm either missing a piece, or what I'm trying to attach it to is not the right part. It has a set of circular threaded rings on the camera side, with each going larger like a step up filter would. According to a couple of manuals (that just show the pieces, with no details), the threaded end screws into one of the eye-cup viewfinder accessories after the rubber cup and it's retaining ring are removed. I have 3 of what I've always assumed were the all-black OEM eye-cups attached to a slip-on rectangular clip, but neither one of the F-2's rings will screw in. One is to big to fit, and the other is too small to grab any threads by 0.05mm at 18.95mm - and that's just the raw size, and doesn't account for the 0.05mm or so thread depth on both pieces. The outer threads on the smaller F-2 ring measures 18.90mm, and the larger one is 21.85. If I remove the F-4 rubber eyepiece an a Contax AX, the magnifier will screw in just fine using the larger ring, so I assume that the AX and any siblings that all have the same round locking ring eyepieces (RTS III, ST, etc.) can use this without anything extra. Every listing I've seen on ebay has no extra rectangular adapter piece that comes with it, but looking at the RTS III manual, it seems to suggest that piece is part of the F-2N kit, so....... Any ideas on what I'm missing or will this ever work at all with the rectangular eyepiece cameras?  |

Hi - I'm pretty sure you have the F-2N Magnifier and not the F2. The rings do not match those on the standard eye-pieces.
The F-2N is supplied with 2 adapter rings - one for the use on rectangular eye-pieces and one to replace the F-4 eye-cup which is for a circular eye-piece. You are missing the rectangular adapter (Eyepiece Adapter 2). If you have the Right Angle Finder N, you should find the missing adapter as it uses the same 2 eye-piece fittings.

It's not at the best angle to see it in the photo, but the hinge piece has "Magnifier F-2" molded under the Contax name, so it's definitely the F-2 model. I do have a right angle finder for both Yashica and Contax... it's just a question of where I put them. I do know that both will work as intended, so I'll dig both out and see if they'd have a matching piece to fit this puzzle. Now I'm also wondering if the pieces I got with this F-2 were mismatched from either one of the other Yashica or Contax magnifiers or angle finders, and I've wrongly assumed the ones I have included the correct parts.

Hiya, Please let me assure you that what you have is definitely not the F-2. The F-2N was always simply marked F-2; hopefully the piccie below will convince you. One of the difficulties is that some people sell the magnifier without knowing there are two types and simply list them as the original and most common version. All too often, the 'F-2' is sold with only the circular mount as the Eye-piece Adapter 2 simply gets lost because the original owner only had need of the circular type as their camera(s) used the F-4 eye-cup.  Magnifier F-2 F-2NThe same eye-piece mounts apply to the Contax Right-Angle Finder and its N version. |

Thank you for the clarification Graham. No convincing needed. :) Comparing the 2 side by side, it obvious that there's a considerable difference at the connection point to the camera... and it's certainly not the same as what I have, nor what it was represented to be. Mine was sold without any box or paperwork, so I guess I'll blame KEH for the error, as they labeled and sold it as the F-2. Even if it is incorrect, I'll happily hold onto it and keep it with the AX where I know it will work as-is. It's unfortunate that they aren't the only retail outlet making the same mistake in their online listings.
At least I'll be armed with what to look for in the future to get the sibling version - as will anyone else stumbling here with the same questions.

I have seen quite a few F-2Ns being sold/auctioned as F-2s and in the past I would contact the seller and advise them of the error. KEH has always been responsive to a clarification on one of their items for sale but I can't say the same of many Ebay sellers so I've given up on contacting them. I'm pretty sure there'd be a small but reasonable demand for a 3D-printed Eye-Piece Adapter 2, especially as the more common Right Angle Finder N is often mis-sold with the same eye-piece problem. |
