Random question - does anyone also have a GH1 (or is thinking about it)?
I have the G1 which is the non video version of the GH1, it's a very nice camera, if you don't want video there are some great deals about on the G1 at the moment & £50 cashback, although there are reports that the G2 is being revealed soon so you might want to wait and see what that has to offer.
I bought the G1 to see if I could get decent results without lugging a huge weight of kit around, the long and short of it was that I ended up selling my 5D and all the L glass, Sure the panasonic will never quite live up to the 5D in some areas but it ain't that far short and in fact has some aspects that are better, although it's not really fair to compare the G1 to a pro quality camera anyway imo.
I initially ordered a GF1 but I like to use a viewfinder too much to go without one, I just find it so hard to compose a shot when my eyes have the distraction of whats going on around an LCD, so I sent it back and got the G1 instead, although I suppose it's something you can get use to, I personally also prefered the feel of the G1, I know you can buy an EVF for the GF1 but by the time you add the price of it to the body it starts working out quite pricey, also from what I have heard the optical quality of the after maket EVF's does not come close the that of the G/GH1.
The one thing I will say about the system is I am amazed how good the IQ is from both the 14-45 & 45-200 for a £200-£250 lens they are increadibly good value for money, however I think some of the other glass is rather overpriced for what it is ie: the 7-14mm f4 being a prime example.
Go find yourself a dealer who has the GH1/G1 and compare it to the GF1, btw the GH1 also has a higher quality video mode than the GF1, my local curry's had both the GH/GF1 which was handy, put them side by side and you will notice that the size difference isn't really that huge.
Oh my god this turned into a mini review
Hope that helps.
