I work at Jessops but haven`t been there for long. I`m always looking to improve my knowledge on SLRs and Flashguns. One of the questions we get asked constantly about SLR's is, "What makes that camera beter than that one". Usually this question is aimed at the Canon EOS 300 compared to other EOS camera like the EOS 30 and the EOS 3. What are the main differences between the 300 and the 3 ? I presume that some of the differences are:- More frames per second better metering system Eye Control Custom settings functions etc etc Are there any more differences ? And do these extra features warrant spending an extra £300 ish pounds ? Can you actually say that the more expensive EOS camera give you a better quality shot ?
