Hi all,

The 35/2.8 and 85/4 take A32 filters, which are 32mm push on filters as I understand it. I read somewhere that the 2 lenes could also use 29.5mm screw on filters. However, they do not seem to have any filter thread on them. Anyone has a easy way to deal with filters on the 2 lenes? 32mm push ons are hard to find. Thanks.

Jason,

I think you will find that the 35mm and 50mm lenses take the 32mm push-on filters. The 85mm lens is a much bigger diameter - I will dig mine out and measure it.
 
The 85mm lens uses 29.5mm screw-in filters. The filter thread is just around the front lens element. They also take bayonet mount filters, a B36 I think. I will check mine later if necessary, I have both lenses with filters on them. I do not use push on filters.
 
Brian, could you check if B36 is usable? Thanks.

Jason.

I'll check this evening. The 85mm F4 on my Retina IIIS uses 29.5mm filters. The 90mm F4 also uses them. I have one bayonet filter on the 35mm F2.8 for the IIIS; dumb luck finding it.
 
Just checked the
1)35mm F2.8 Curtagon: I have a Bay36 to Series VI adapter on mine. It also has threads but will not take the 29.5mm filters. I think it is 30.5, but have none to check with it.

2) 85mm F4 Tele-arton: I have a Hoya B36 Skylight 1b on mine. It will take 29.5mm filters, and I put one on it. I use a 29.5mm to Series V adapter. This helps clear the front element which curves out. A deep inset filter is a problem.

3) The 90mm F4 Tele-Arton takes 29.5mm filters and does not have a bayonet mount on the outer rim. The outer rim is not threaded. I keep the 29.5mm Series V adapter on it as the front element has an issue clearing some inset filters. A also have a polarizer for it. This lens does not RF couple, and is used for the reflex-S.

50mm F2.8 Xenar, B36 and 29.5mm filters. No problem with clearance.

28mm F4 AND 50mm F1.9 (RF COupled) AND 135mm F4: 58mm filters.

50mm F1.9 SLR-only (2ft close focus): 52mm,
135mm F4 (Black) SLR only: 52mm

200mm F4.8: 72mm, no RF coupling.

I have both the 50 2.8 Xenar and the 35 2.8 Curtagon and I can use my 29.5mm hood on both of them.

Not really. That lens was made for the Retina Reflex and therefore does not have the cam that brings up the proper frameline.

Note that I listed the 90mm F4 as "This lens does not RF couple, and is used for the reflex-S."

I went ahead and listed the non-coupled lenses as well, I use them with the Reflex-S. They mount fine on the IIIS, but do not engage the RF pickup.
 
I can't tell the difference in performance between the 90mm and 85mm Tele-Arton. I walked into a camera shop that had an Instamatic Reflex outfit with the 90mm lens for ~$50. It is a nice lens, I wish Kodak had kept the coupling for the IIIS. The 85mm is one of my favorite lenses, and is quite sharp.

Brian,

How do you carry your lenses around? I have snap on caps for all my lenses, and just use the bases of the bubbles as rear cap. However, most of the bases do not lock on to the lenses. It is very annoying.

Jason.
 
Except for one bubble, all of mine are working.

For lenses that do not have bubbles, I found that film cannister caps used by some of the vendors (Fuji I Think) work as rear lens caps. They are the opaque soft plastic with insets for the 35mm cassette spool.

For the larger lenses, 58mm and 52mm caps are easy to find. The smaller lenses (not in bubbles), I use the home-made rear cap and a soft case. I have filters on all of them.
