It's been a while since I've been on the forum-but hope to get back into the "fold" now. I have finally decided to buy a dslr - beginner/entry level only. I really like Canon, but am also open to Nikon or others that you would recommend. I do not expect to take award winning magazine pictures, but do want to take better pics of nature, the canyons, mountains, etc. 2nd thing I would like to ask, what is your opinion of refurbished cameras? I am hesitant to upgrade to new because of cost, but also afraid of what I'd get on refurb.
I currently have a Canon G12 now, it takes awesome pictures. We went to Grand Canyon and explored N. AZ., we also spent time in CA on the trip, Tahoe to the deserts, and all the pictures were beyond what I thought I was capable of but know that it was really the camera. The only problem, was the wide angle - I tried doing the stitching but wasn't great at that. We've just returned from VA doing the Civil War trails and stopped by D.C. while there. Went to the National Cathedral and was very much aware of of my limitation when trying to capture the Cathedral My husband wants me to go ahead upgrade to one that will let me shoot what I see in my mind. Thanks

You're not (quite) by yourself Anand ! I, too, am a believer in "you can get used to using anything after a short learning period". Far better to go for the best that fits your main purchasing criteria and you can afford at the time, then learn it and practise using it. Surprising how quickly humans can form new habits !

As far as "mirrorless" is involved ....... I suggest the OP learns about what's currently available before making any kind of decisions. There are lots and lots and lots and lots of opinions here from camera enthusiasts about "what's great for THEM". Great knowledge (unbiased) from a well-seasoned pro here about all the mirrorless camera systems ........
