It was important to me compared to the kit lens higher light intensity for shooting in not so optimal light, the Olympus MFT Pancake F2.8. Certainly not bad, after a stop better than the kit lens that starts at F3.5. But then I looked at a Arbeitskollgen the model with the equivalent 40mm focal length of Panasonic.
Sure Panasonic model is about 100 euros more expensive, but offers a much higher luminous intensity of F1.7. The lens is very well made and makes a high impression. Compared it might be a bit heavier and larger than the Olympus counterpart. Nor is supplied with a small, Lecht padded nylon bag, also beautiful. The focus ring does not slide too difficult and not too easy, just right.
Even though I have only made a few interior shots, the focus is subjectively absolutely convincing, but is surpassed by the magnificent light intensity. Shooting in dim light and 1/30 second without a tripod are quite possible (unfortunately, the E-PL2 not also has a housing-internal optical image stabilizer, the Panasonic GF1 and models Gf2). Oh, filter with 46mm diameter can be used without any problems.
Pocket Suitable for a MFT camera through the Pancake course still not, especially since you have to change at a fixed focal length. Comfortable What else does the Zomm then makes the photographer on foot, but he is also inspired by a little food for thought, I feel in any case that I am with a fixed focal length longer than the optimal cut-try with Zoom. Of course I would never give up my zoom (14-150), but the pancake still fits easily in addition to the pocket. :-)
Conclusion: Better I had the 100 euro compared with the Olympus pancake can not create more, agree to the "brand foreign" lens on my E-PL2 very satisfied and would buy it immediately.
