I have Canon EOS 450d camera that I bought about 7 years ago and till now I have shot for about 15k photos. Lately appeared problems taking shots and when I pushed the button, nothing happened. I thought that camera is damaged but then I understood that the lens has some problems and after testing it by switching MF mode to AF, it worked so the lens doesn't work in MF mode. So, I need to repair it but I think that at this time I will search for a new lens, but I would love to get a better one compared to the basic lens.
How do I decide on a specific lens to fit my needs and budget? Mostly I shoot landscapes, family (outdoor/indoor), activities. Budget - around about 100 euros.
