I regretfully tried out a different case with pick and pull foam (*** electronics case) that a few folks recommended for the Phantom. I should have saved that money and used it for this GoProfessional case. It is a perfect fit for my P2 v2.0 and FPV gear! It's a high quality case that has a place for everything and a superb fit. Highly recommend GoProfessional!
At 2800mAh these batteries should give me about 7% more run-time than Canons 1865mAh batteries. They also cost roughly 1/6th as much. In addition to more power and less money, I get the knowledge that the two batteries belong together. It has always been a best practice to never mix rechargeable batteries of different ages. This has something to do with the older battery not being as efficient as when it was new. When you buy a two-pack there is the highest likelihood that they left the factory together and are the same age. Buying them in singles from any but the best supplier could mean that one has been on the shelf for months if not years, and it's mate may be just in from the factory. I typically buy straight Canon gear, but this time I'm going with a pretty standard piece. They do not go directly into the camera as I use a battery-pack grip. This means if they were to malfunction in any way but to experience a spike (which is most unlikely at best) they cannot hurt the camera, just the grip which is far less expensive. The only reason I could not give five stars is because with batteries time is the only true test. Once I've owned them for ten years like my Canon batteries in my other camera, I can weigh in on that.
First of all this lens is excellent and very sharp. It is replacing my Canon 50mm 1.4f. Focusing is fast and spot on. I am pleased with the results. Contrary to the previous reviewers when I registered my lens I got full 4 year Sigma USA Warranty. I don't know if it's for all the purchases of this lens or if this is a hit or miss type of thing. For what it's worth the overstock FAQ does say it has full warranty and this has been my experience. Very pleased with purchase.
