I have bought and sold the VF2 a couple of times. Currently have one. But a VF3 came for sale on this board for <$100, so I figured "what the heck" and grabbed it. WOW! I think I like it much better than the VF2. Now, I never purchased the VF3 before, because the used vf2 prices were pretty close to vf3 prices, and why not go for the better resolution, right? In fact, I think the VF3s existence is propping up the used price of VF2s. If there wasn't a vf3, then there'd be more pricing pressure on used vf2s, but vf3s create a market bottom for used vf2s (i.e. "if you don't like my used vf2 price, then just go get a vf3"). Any rate, back to the main topic. I wear glasses, and I don't want to take them on/off all the time. I've always used the EP9 eyecup on the VF2, thinking it was better to keep out bright light and also somehow it protected my glasses more. But this makes the VF2 very large, and of course it doesn't lock, so I'm always fiddling around with it, to get it into/out of a bag. But here are my findings on the VF3 vs VF2: 1. The VF3 locking mechanism is a welcome relief 2. The VF3 is a much more compact size. It still adds bulk to an EPM1, but it's much nicer 3. The VF3 resolution is poor compared to the VF2, the screen size is smaller (more on that in a moment), and the glass is imperfect, so the edges of the image sort of "swim". 4. The VF3 is prone to burn out the image, whereas the VF2 makes a better approximation of the exposure, though the VF2 is still imperfect. 5. While the image on the VF3 is smaller, this is actually better for me wearing glasses. With the VF2, I can never see the whole image. The viewing portal is too small. With the VF3, even though the image is smaller, I can see the whole frame. 6. With the EP9 eyecup, it's even worse on the VF2, so I removed the eyecup for the first time, and I like the VF2 better (in terms of seeing the whole image) but the eyepoint for the VF3 is still better. So, in short: the VF3 is smaller and more secure and cheaper. The smaller image is actually a blessing, in that I can see the whole frame. And though the image tends to be blown out, I just turn on "highlight clipping" and I can see if it's blown out or not. If I was doing manual focusing, I would reach for the VF2. But for AF lenses, where I'm using the VF for a) stability and b) viewing in bright sunlight, it seems to me that the VF3 is a very nice choice, though I think $170 is too expensive, and am happy for the used price I paid.
