And actually the range missing is only about 80 to 105 if you pair the 18-55 with the 70-300. I didn't convert the 55 to full frame equivalent. So in full frame terms you have a 28-80 ( roughly ) and a 105 to 450 with that combination. But again, I'd prefer a 18-70 which I consider a better lens with no gap in the range at all.
Photography - I do it for passion, not for a buck! It's just better that way.
