So what is the USP of the G1?
Well, it's the first EVIL camera in human history. We all know the pros and cons of the EVIL system, but nobody had the guts to make one until now.
Apart from that, it allows you to use most MF lenses ever made, including the Leica M rangefinder lenses, which cannot be mounted on regular 4/3rds, so neither on others.
It must be remembered that the whole point of panasonic developing the new micro 4/3 is to attract those that currently use compact cameras some 92% of the camera market approx... into discovering the world of improved image quality.
If Panasonic are too succeed in this quest the camera must be small, easy to use and understand and good value. Most people currently with a compact camera are not going to know about the EVIL System or really care about it IMHO.
I do not think anyone who is already in the DSLR world will be itching too get hold of the G1 as it doesnt offer anything above what they probably already have or could have with an Olympus 420..
Therefore the target market must be those moving up from compact for the first time.. If this is the case i think a fixed lens version which uses a similar approach in terms of size and all round functionality of the FZ18 or FZ28 plus of course good pricing (around £250 to £300) will be the real camera to make people move across in large numbers... Sadly i dont think the G1 is that camera...
In fact i would go one step further and say if Panasonic really want large numbers of people to buy into this technological move i think they must provide a fixed lens solution similar to the FZ28 as few people are going to want to change lenses or carry them with them etc. There will of course always be the enthusiasts who will argue that they love the DSLR plus all the kit that goes with it..but it isnt going to attract large numbers of people.. which is of course what the micro 4/3 is really for..
