I was pretty lucky to get my hands on an EOS MKII in early 2010 and have been very happy with performance. I noticed whilst looking through several forums that the new MKIII was coming out shortly and then got an email from Jessops to say they were taking pre orders. Having looked at the spec on their site - http://www.jessops.com/online.store/products/84404/show.html I was a little confused as to why it is a lot more expensive than the MKII. It looks like a great spec but so is the MKIII so can anyone enlighten me as to why this is such a great camera? It looks to me like a minor upgrade to the MKII .. Whilst I am lucky to have such a lovely MKII , I am always on the lookout for new tech but not if it isn't worth the investment. I am no expert on hardware and have in the past relied on advice from many friendly people on forums such as this. I would appreciate some advice .
