Canon LTM Canon finder for Canon 100mm f3.5

[mpaniagua]

Hi, just got a Canon 100mm f3.5 with case and finder. Got a question about the Canon finder:

Just how do you use parallax correction? Finder is a little weird, because it can be tilt by pressing a pin on the base but not sure how to use it on my M6 or LTM cameras.

I got the Canon 28mm finder with a similar mechanism, but that one has a little level that you can move to set it to the focusing distance; the 100mm finder lacks such level.

28mm finder

100mm finder

Any ideas?

You most likely have a finder for a Canon V, L, or VI series camera, which has automatic parallax correction. Looking at the bottom of the finder you should see a little ball, which connects to a similar ball on the V, L or VI-series camera. You can still use the finder on any other camera, but you’ll have to guess composition when focusing close.

You have a late model finder designed to work with several late model Canon cameras that had a protruding pin in the flash shoe, linked to the range finder that provided automatic parallax compensation. There is a hard to find item that would go between the finder and shoe and provide manual parallax adjustments. The good news is that the Canon 100mm f3.5 is an excellent lens. Joe

So most likely, if I want to use it on my Leica's, will need to put something between the shoe and the finder so it will stay at a reasonable good position for general purpose? Or use another finder I guess.

Lens it in gorgeous conditions, probably mint. It will go along with my Canon 28mm f3.5,Canon 50 f1.8 and Canon 85mm f1.9, probably will get a lot of use with the Leica IIf.

Thanks.

So the natural position is for far focusing? I don't I will use it closer than 3 mt.

Also, if I use it with my M6, do you think I can safely use the 90mm adapter and use that frameline's?

Looking at one of my auto-parallax finders, it look like the natural position on a normal camera is somewhere between infinity and close focus. As for your frameline question, you can use the finder with a 90mm lens, you just have to compensate when you compose.

If you keep the finder, shoot a few test pics. This will tell you a lot.

Actually you'll have to guess composition when focusing at distance. Without correction, your 100mm finder will be pointed downward for a close distance. There are at least two ways to correct this problem. The first is a Canon contraption called a Finder Coupler. It has a lever just like the one on your 28mm finder and fits between tne camera and your 100mm finder. These are hard to find and usually expensive. The second solution: Cheat! Look at the front of your 100mm finder. Push on the pin. You will see that the black base of the finder raises up from the silver base that fits in the shoe. What you need to do is stick a shim in this gap to hold the finder up at the infinity position. I measured the shim thickness needed to be about .020 inches. Of course you have to guess at any parallax correction. Good luck whichever route you go.

Thanks for the comments. Will use the 90mm framelines on my M's and play a little with the finder on my LTM.

Thanks will try that with the Barnacks 🙂

You might watch e bay for one of the old style finders. They come up now and then at reasonable prices. Joe

 

[mpaniagua]

you mean the long tube type?

The older long-tube type will work. Canon also made manual-parallax versions of the automatic-type you currently have. You can find them on eBay on occasion.
