No, usually the Vf-3 sells for cheaper than the others. I am seeing the VF-3 for under $100 USD. I bought one a while ago for my infrared E-P2 and I picked the "3" both because it was cheaper than the others and also it is the only one (I think) that has a positive lock when you mount it requiring a push button to unlock and remove. I didn't want the VF getting pushed off the camera either in my bag or holding it at my side when walking.It is interesting that the VF-3 (which was originally made to be a cheaper solution with smaller resolution that the VF-2 viewfinder) is slightly more than the VF-2.
Yes. The lock was added in the VF-3. I believe the VF-4 has more resolution (so VF-3 -> VF-2 -> VF-4).Is it the VF2 which is higher resolution than the VF3, but does not lock in place, so you run the risk of accidentally pushing it off? I think I nearly lost one which came off while the camera was over my shoulder.
I had the E-PL5+VF-4 combo for 3 years till the PEN recently developed IBISitis and I got an E-m10mkii on sale as I find repair too costly for a 2012 model camera. Now I am selling the VF-4 and if it does not leave the premises after all I am thinking of finding a used E-P5 for it to make a new home on for posterity.Currently shooting with Oly E-P5. Considering the cost of the VF viewfinders, thinking it makes more sense to buy a used body with built in viewfinder as a 2nd body to carry. Thoughts/suggestions
