Hey friends! I have a quick question about the R camera itself. I was recently playing with an old R4, and noticed the viewfinder is simply huge and bright. I looked up the details online, and found out it's based on an old Minolta XD-7 camera and has 0.87X magnification and 94% coverage. It's a pure joy to use. Why are modern cameras only 0.7X or 0.75X maximum? Is it to facilitate 100% coverage? It truly detracts from the experience when focusing with manual lenses.

The root problem, as I understand it, is autofocus. The phase detect sensors need light; a semi-translucent mirror directs light away from the viewfinder and onto the autofocus sensors. To keep the viewfinder bright, then, they compress the image (reducing magnification, as you say), and also changed the focusing screen to one that transmits more light but does so by increasing apparent depth of field.

When comparing magnification numbers, it is important to note what length of lens is used. Some manufacturers use a 50mm lens at infinity on cameras with an APS-C sensor, just like what was the de facto standard in the film era; this gives the same magnification specification as a 135-frame camera, because objects in the viewfinder are the same size, but the size of the viewfinder is much smaller. To get equivalent numbers, the lens needs to be 50mm-on-135-frame equivalent, or about 35mm for APS-C cameras.

Manual focus on a DSLR is tremendously helped by using a manual-focus screen, like the Canon S-type, which some companies (focusingscreen.com) cut down to fit other brands of DSLRs. But for enjoyment of the viewfinder, a pre-autofocus SLR is hard to beat. (I moved to film because I loved that large viewfinder so much. I've done my best to not look through a medium format viewfinder, because they will be larger and more immersive still.)

Cheers,
Jon

Jon,

I like your photos more and more. I generally like punchiness, but yours have a subtlety to them that seems to grow in character the more I look at them. I might have to experiment more to see if I can't achieve that.

Cheers,
(another) Jon

I've been following this thread for awhile now and finally can join the fun. I received my first Leica lens this week and I'm definitely liking the results. I have a feeling this won't be my last Leica glass.

These were shot using the Leica APO-Macro 100mm on a 1Dx.

JSPHOTOS> Congrats on your new APO Macro 100.

I like the Cello pic.
But even more, the B/W contre jour portrait is very airy and attractive.

Jim, congrats on your new R 100 APO!
My favorite of the set is the cellist image too.
The 100 APO was my first Leica lens and it is still amazing today on my 36mp D800E. Enjoy that great lens!

Thanks Wayne. I shot a D3s and D800e up until January when I switched camps. I do miss the resolution of the D800e and can only imagine how incredible the images look on that body. Post a photo with that combo when you have a moment.

Thanks JP! I have a matte focusing screen, but nothing is quite as nice as an immersive 0.87X viewfinder!

Couple weekends ago, 6D 50 cron. I think shot at 5.6 or 8.

Tested my new Leica R 60mm macro after receiving my Leica-R to EOS adapter. I will be struggling with manual focus and no IS but this is what I took early evening tonight. I think I am going to like this lens, but don't tell my Canon 100L. No pp only cropped.
