I just wanted to get some input on this. I usually prefer portability with m4/3 gear and the E-10 certainly fits that criteria. With the pancake zoom lens I can fit the camera into a small bag made for compacts which is nice and saves space. Adding the grip adds weight and bulk so I'll need to use a larger bag. How do you guys like the grip on yours, does it balance out the camera well with the lighter lenses, or do you find that you don't need it when used with smaller lenses and primes? I'll be using it a lot with a big lens, the 14-140mk1 when on holiday, which I've never had issues with on my GF3 or E-m5, and I like how it feels with the E-m10 especially with the more pronounced curve at the front. I don't know if I really need it but if it helps with the comfort and handholding for long periods it might be worth the 50 usd for a used one and near 70usd price for a new one which is how they are priced locally.
