I have one on pre-order for 3rd of July...
The Samsung NX series will have APS-C-sized sensors, that's the one I'm waiting to see.
I think Panasonic has done great on developing the 4/3 sensor tech to catch up with the APS-C sensors. Current reviews and comparisons on dpreview with the latest DSLRs confirms this.
The Samsung NX will compete with the G1 series. The E-P1 is a difference class and audience, I think. I still have grave doubts about the quality of lenses the NX system will use.
The E-P1 is an evolution of existing tech that Olympus has refined over a few years from the small E-420 to the current E-620. The 17mm pancake release is because the release of the 25mm Pancake (for their DSLR line) sales exceeded beyond Olympus expectations. They miniaturized their in-body IS system on the E-620 and ported that over to the E-P1. I have a E-620 and the IS really works it is great. So alot of existing tech on the E-620 has been put into a smaller package that is the E-P1. I think that needs to be applauded.
The AF may not be as fast as on the G1, but if it is as fast as the LiveView on the E-620, I dont think that is bad at all. Plus, I have heard that the speed of lenses is a factor in AF speed. None of the two lenses released so far is particularly fast. I look forward to faster primes in the near future.
I have heard on the grapevine that Leica will release some lenses in collaboration with Panasonic. They will be pricey though!
But the more choices the better. I am sure some wont mind forking our for a super-speedy prime lens.
By the initial positive response around the world, it looks really healthy for the future of micro-Four-Thirds.
Looking to having more fun with photography next week! I ordered the silver with 17mm Pancake kit.
