<p>Thanks for the response. That does indeed seem like the obvious reason for it. I just didn't really see too much of a purpose with it because I remembered the exposure count of the roll of film I would put in to use, and just kept an eye on the frame counter. <br /> But then again, the frame counter disk could , if not careful, easily be nudged out of place and the "final frame reminder ring" as I guess it would be called would ultimately not be very useful.</p>

<p>Hey All<br /> Just a quick question regarding a small detail on the Canon "Leica-Copy" Rangefinders (IIF, III, IVSB, etc). Some of these cameras had this small feature and some didn't. I notice it appears most often on the IIF2 and IVSB models, but there were some of these that didn't have it, as well as some others I believe that usually didn't but occasionally did. <br /> The detail in question is a notched ring between the film wind knob and the frame counter disk. If I recall on my IIF2 which I sadly no longer own, the notched ring was able to be rotated independently of both the winder knob and the frame counter. It also had a red indicator dot on one point of the diameter. My question is, what was the purpose of this ring and why did some examples of some models have it and others didn't? Although it might actually be fairly obvious, the only purpose it really served on mine that I knew of was it made it just slightly more difficult to accidentally nudge the frame counter disk out of place while winding the film. <br /> None of the Leica cameras (I, II, IIIa, IIIf, etc), which the Canons were based on, had anything similar that I am aware of. <br />The example below has this feature. <br /><br />http://cameratique.com/CANON-IIF2-LEICA-RANGEFINDER-TYPE-COPY-1-3.5-50mm-COMPACT-LENS-CASED-CAP-CLEAN<br /><br /> Thanks!</p>

<p>Hello all</p> <p>I am using an Energizer 357 silver oxide battery in my Minolta SRT 101 for the light meter. However, it is a 1.55v battery rather than the 1.35 volts of the old mercury battery these cameras used. </p> <p>I heard one trick is to set the ISO dial a bit slower to "trick" the meter into giving the correct readings for your film speed. </p> <p>So if I am using ISO 400 film, would I set the dial at ISO 200? Lower? Higher? What about for other films such as 100 and 200 ISO?</p> <p>Thank You. </p>

<p>Thanks for the replies<br> Rick,<br> Yes, I can adjust the aperture of the M42 lenses using the ring when they are attached to the adapter and camera. It only allows the aperture to fully open or close while the lens is set on the Manual mode.<br> Also, looking in the viewfinder of the FR1 while adjusting the aperture of the M42 lens appears to have the same effect of holding down the DOF preview button when I have a C/Y lens on, in that the view "lightens" or "darkens" depending on how I have the aperture set. With the C/Y lens, it does not do that unless the DOF preview is held down. <br> Interestingly, despite what I said above, the C/Y lens and the M42 lens show the same meter readings when the two lenses were set at the same aperture. It's handy that I was using almost identical lenses for the experiment (Yashica/Yashinon 50mm), one obviously being older and the mounts different. </p>

<p>New here, just had a simple question...<br> First off, Amateur alert...<br> I bought an adapter so I can mount M42 lenses onto my Yashica FR-1 camera which has a C/Y mount. The M42 lenses I have are older Yashinon and Tamron lenses. Before I use anything, I want to know if these would work properly together. The aperture range indicator in the FR-1 viewfinder does not function with the M42 lenses attached but the light meter still appears to work.<br> Thanks</p> <p> </p>
