1.33 crop and viewfinder explanation?

I understand how a 50mm leica lens, when used on the M8, will be a 66.5mm lens due to the crop factor of 1.33. However, what I can't find an answer to is how the viewfinders frame lines handle the crop factor. There aren't framelines for 66.5mm lenses on a Leica, so how does this work?

 

Thanks.

The lens is still 50mm no matter what the crop factor is - it simply restricts the field of view compared to an uncropped sensor, just like mounting a 35mm slide in a mount with a reduced size rectangular cut-out.

 

I understand, but you never know. I was just hoping that it wouldn't be a true 50mm frame line while using a 67mm equiv lens.... so things would be cropped and what I see isn't what I get. I knew Leica couldn't be this dumb though.

Meaning that I will get more in than I want?

 

I believe that Leica determined that it's better to get a little more in the picture, than not enough. It's easy to crop any unwanted area out of a picture, but impossible to add back something thats not there. :)

But we are talking about a little bit more... not a big amount right?

With practice it is easy to walk closer and get the framing you desire. It does mean checking after the first shot, though.

As far as I can tell, it's only a small amount, and I wouldn't even notice it if I wasn't aware of it. Then again, I rarely frame my subjects so tightly that a little extra is noticeable. I find it better to know that I am not going to lose anything on close-ups. :)

Ok, I'm just not a big fan of cropping outside of the camera. I'm a bit old school in the way that I like to get what I wanted in camera. However, as someone who used an M6 for a long time and is currently using an M2, I'm aware rangefinders are not perfect with regards to this aspect.

Sadly, cropping is often a necessary evil. HCB, the master would disagree but he never experienced shooting with the M8.

I was considering upgrading the frame lines but the difference was too minimal to justify the inflated cost. After Leica jacked up the price to upgrade I let go of the idea.
