not reli a must but just some extra features coz it allow me choose focusing point and snap in the speed of light rather then press left and right 1 by 1 using button.
base on my own understanding, crop factor is all refer to 35mm format.
for eg dslr with 1.5x crop factor when mount on 18mm lens, it actually is 18mm X 1.5 = 27mm in 35mm format
for m4/3 crop factor is 2 where the kit lens 14mm actually is 14 X 2 = 28mm in 35mm format
for nikon 1 with 2.7x crop factor where 10mm kit lens = 27mm in 35mm format.
compact camera with 1/2.2" sensor usually have 5.5x factor
for dslr, they have their own lens for Full frame. Eg Nikon for DX (crop sensor) and FX (full frame = 35 mm eq) lens
Hmm, that's quite convincing actually.. I thought the focus could be toggled by turning dial around the lens, isn't it?
I'll make touchscreen as optional for now, I suppose not many support touchscreen yet.. At least not the D5100 =x
I can't recall if the GX1 has a touchscreen, but the power zoom sure looks nice =x
By the way, great photos taken of the Hennesy Artistry, thumbs up!

picture speaks a thousand words...
by using the full frame sensor as reference, the field of view (FOV) of other sensors are relative to full frame...
at the same focal length, the 1.6x APS-C sensor FOV is as if cropped when compared to full frame...hence crop factor...
Wow, so the smaller the crop factor, the better. It can be concluded that way huh?
Now I'm really understanding what a crop factor is, thanks a lot highwind85.. Now I feel more light headed as I'm beginning to understand certain terms already XD
