I've had the 60D for a month now and it seems like a good time to summarize my early impressions. During this time I've clicked off nearly 1900 photos. I took it to Indianapolis to photograph and video record events at the Percussive Arts Socity International Convention; I've photographed two concerts; I photographed the LoneStar Classic drumline competition; I shot a wedding; and I shot a family's Christmas photos. That's a pretty good workout for a new camera.
What works?
* Pretty much everything. The AF, metering, high ISO noise suppression, speed, image quality, etc. are superb.
* Off-camera flash capability. It works easily and flawlessly (error below notwithstanding). It is far more convenient than using cable or RF triggers.
* Body. The robustness of the body makes this worth every penny over the price of a T3i/600D. I used it in a moderate rain storm without worrying about it being damaged by a smattering of H20. The grip is perfect for my large hands. The shutter just sounds so tight and solid. It is heavy enough that it feels steady and solid, yet light enough that it is easy to manage. It is a nice counterbalance to the weight of the EF-S 17-55mm f/2.8 IS USM lens that I primarily use.
* Dials and buttons. Several reviews maligned the vague feeling buttons and condemned the eight-way rocker control. This "shortcoming" is much ado about nothing.
* SD memory card. So far I have discovered nothing to hate about using these SD cards. I was prepared for the worst. This feature made me hold my nose when I purchased this camera. I wanted CF memory cards like my other DSLR. It's no big deal. I would have been buying new larger capacity cards for the new camera anyway.
* Batteries and battery monitor. These batteries seem to go forever. I've only had to recharge them once. That was just prior to shooting the wedding. At that point each battery had more than 25% capacity left after shooting about 1000 photos, many with a flash. After shooting the wedding, each battery is only about 25% depleted.
What doesn't?
* Live view is quite limited for taking photographs. While it's great to be able to swing out and tilt the LCD when taking a photograph with arms extended above your head, it is really quite slow and has a hard time focusing. I'll only be able to use it for static shots. It is unusable for photojournalist-style shooting of a mass of people moving around, such as of people dancing at a wedding reception.
* Error: "This option not available when external flash connected." On Saturday while shooting the family, I removed the flash and attempted to use the off-flash feature when I started getting this error. The camera would not let me open the internal flash for the same reason. I was really quite frustrated. Eventually I had an assistant hold a reflector and I bounced the flash into it from the shoe. I later discovered the problem is a tiny switch located under the right hot shoe rail that was stuck in the down position. Apparently this is a common Canon problem. I'm glad I know how to easily fix this should it happen again, but I would have been furious if this had happened at a fast moving wedding.
* White balance. Actually, I can't say this doesn't work. It just doesn't work well all the time. I couldn't get the WB right at the wedding. In the future I may pack a white card so I can custom set the WB for difficult situations like that. Having shot RAW, this is easily fixable, but it definitely lengthens post processing.
