The so popular compared to the successor 70D can be summarized shortly after my previous experience. The 70D scores with 7 frames / second, compared to 5 frames / second in the 60D, but who really needs it? From ISO 3600, the 60D even has a better picture quality. The gridlines in the viewfinder of the 70D can be supplemented with the 60D by the very favorable purchasing such Mattscheibe (about 25.- and easily replaceable). Replacing the focusing screen, I can highly recommend from experience. The case size is the same for both models. In both models, I recommend the purchase of the battery grip. The camera is then significantly better in the hand, which is especially suitable for straight men hands. After the successor of the EOS 7D comes on the market in September 2014 I can currently only ever advise against the purchase of the EOS 70D, because you get much cheaper at the moment, the housing of the current EOS 7D. (From about 850.-) And the current EOS 7D is still an APS-C camera of superlatives. For the EOS 7D no need to purchase additional battery grip, because the housing opposite the 60D and 70D is significantly larger and very good in the hand. What the current 7D also so unique and makes so recommended against the 70D is the fact that the housing of the 7D is made of magnesium alloy and is protected against dust and spray the entire housing. Therefore, either the EOS 60D or equal to the still current EOS 7D Buy.
