Leica LTM The best accessory for an old timer

[Rico]

I even use SBOOI on my M4 (and its 50 BL isn't too shabby). I like external VFs for their bright, uncluttered view. They also bring your friendly face from behind the camera to engage the subject. I have SBOOI, SGVOO and SHOOC for 50-135mm coverage, and just ordered the C/V 35 and 28 chrome finders.
