Lainer, I use a DP2M with the Vf21. I need glasses to read,-250 to 275, and have no problem with the viewfinder. The viewfinder is so small I don't even know its there but it's great in bright sun. The Voitlander finder is a better optic, but is a bit bigger. My 2 cents on the L bracket and grip is this....I love the merrill because it is small and light, so why put a big heavy RRS bracket and grip on it. Richard Feneric makes a grip that is small ,light and works great. I walk around all day with the Merrill just hanging on my finger, and even with bad arthritis I don't even feel it. I have his grip on all my cameras. For an L bracket I use the fabulous JTEC bracket. Again small and light. Just some other options for you to Google and check out......Max
