Can I mount old finders on a Q?


Recommended Posts

This may sound like a strange question but I was wondering if I would be able to mount an old finder on the Q? I really love the design of the Leitz VIOOH, the Leica Brite (SBOOI) and Leitz SHOOC finders and since I don't plan to buy an M anytime soon I was wondering if I could mount them on the Q? Even if it is for esthetical purposes only.

Out of interest, I've tried two 28mm finders, a Ricoh and a Sigma, and both are a slightly slack fit in my Q's hotshoe, and can be dislodged too easily.

 

At my usual shooting distance of 2-3 metres, both 28mm finder's field of view is significantly narrower than the Q's EVF.

That is the safety factor taken into account in all optical viewfinders, to make sure all you see in the finder is on your picture.

To improve this manhood invented the SLR and later on the EVF.... wysiwyg

 

in this case, it's because the Q is not 28mm. Which is also why I like it so much.....it nicely complements the 24mm Lux on my Monochrom :p

Err...AFFAIK the Q is 28 mm. However, this is given at infinity as focal length changes with focusing. A lens gets longer as you focus closer.  At a guess (there are exact formulas for this which I am too lazy to look up) I would say that the Q 28 lens  @ 2-3 m. will have  the angle of view of something like an 31 mm lens at infinity.

Tks. I should perhaps add that I've only done very casual 'testing', I.e. hand-held eye-balling against reference features.

 

I originally paired my Q with a 28mm Summicron on my MM2, and was disconcerted to find the angles of view very different for my usual shooting distances so I now pair it with my 24mm Lux as they seem to have a very similar FOV at close range (2-3 metres). I'd be interested if someone did some proper testing...I'm lazy too !

 LOL...I love it when someone on Facebook says something, and it becomes gospel. This misinformation has been spread around since it was discovered that the lens is corrected in software. Someone claimed it was a 24mm lens not a 28 and then it spread.

 

What defines a 28mm lens is in the design...you can't determine a focal length by comparing images as some are doing. Anyone want to cut their Q in half and dispel this rumor?

This older 24mm finder works well, I don't have a 28mm finder.
