Thanks miki g. I have actually taken the plunge and bought a second hand full frame body so its a matter of upgrading some lenses to go with it now. I am looking at a 24-105L to start with but am open to suggestions for others. Thanks again for all the advice!
Thanks for the replies Sinead and Miki g. I am aware of the extra expense involved in going full frame. It is definitely not “gear lust”, I have been shooting with APSC gear for four or five years now. I mainly shoot landscape and portraits but I am really no longer happy with the image quality I am getting. I am lucky enough that I have had the opportunity to try some Canon L series lenses and a full frame camera. I was amazed at the difference in the image quality I could achieve with them. Thanks again for your input, it certainly has given me food for thought and made me take a long hard look at my photography and where I am going with it. :)
Thanks guys, appreciate your input. I am aware that some of my lenses would be redundant if I go full frame Alan and am prepared for that. Declan makes a good point about whether equipment is the real issue or not. I will have to give that some thought!!
