<p>Thanks for the input so far, everyone. It looks like everyone is leaning a little towards the M3 plus Summicron? I'm pretty sure either way I can't go too wrong.</p>
<p>Stephen: The meter is probably a non-issue the more I think about it. Chances are if I decided to go with the M6 I'd use the meter, and if I went with the M3 I'd just estimate. I have handheld meters if I need to shoot something specific. It's certainly a tough call for me between the Summicron and the Nokton. The pros and cons don't really tip one way between the two. The Summicron and Nokton have negligible size and weight differences. The Nokton is faster, but it doesn't feel as good as the Summicron to use. The images seem pretty pleasing to my eye from both lenses. In the end this may come down to just blindly picking a combo, haha.</p>
<p>James: I read you on the M3. Of course that would make the most sense logically for a 50mm only setup. However, I find that shooting 50mm on the M6 with the 0.72 finder gives me more of a view of what is going on outside of the frame and lets me <em>cut out</em> a picture, if that makes any sense. Of course the M3 would probably allow me more accurate focus and framing at speed. The accessory meter I have is the MC and it's <em>fairly</em> accurate, though not different enough from estimation to have a permanent place with the M3, especially in dark situations. Luckily I have a lot of my daily lighting pretty dialed in at this point (subway, Midtown, etc). </p>
<p>Bill: You're right, it's very silly. However, it would save me time through avoiding the "which camera should I bring" thoughts for a year - which is probably enough justification on its own. Plus, I'm not a professional anymore so there are rarely scenarios where I would just have to get <em>the</em> shot. There's always something to be said for a little bit of standardization. </p>
<p>Robin: I agree, especially when I'm in Midtown where light is already pretty scarce at this time of year. The Nokton is pretty dialed in on both bodies, as is the Summicron. Flip a coin?</p>
