First off, I need to start with how happy I am to be a part of this forum and that I am looking forward to speaking with you all and hopefully finding answers to my problems.
When it comes down to photography, I consider myself a enthusiastic hobbyist. I mainly shoot landscapes and nature (flowers, leafs, small insects). I currently own a Canon EOS 80 D and a EF-S 17-55mm f/2.8 lens.
Recently I started to do some "experimental" abstract shots like close ups of old leafs showing there structure and stuff like that. But the results are not very satisfying. So I figured out I may need a proper macro (zoom) lens.
So this week I did some research and checked out some websites for classified adds and I found a few lenses suitable for my camera on the for sales website http://www.for-sale.co.uk/canon-macro-zoom-lens. After some more investigation I nailed it down to the following ones:
* Canon EF 100mm f/2.8L Macro
* Tamron SP 90mm f/2.8
* Sigma 105mm f/2.8 EX DG
So what do you think about these choices? Are they suitable for my purposes? And which one should I pick? Price-wise the Canon is the most expensive lens, followed by the Tamron. The Sigma costs slightly less than the Tamron. I also know both, the Canon and the Tamron, are weather sealed. I don't think I need that feature. So should I go for the Sigma?
To save some money I was also thinking about buying a used camera lens. This way I can maybe get a good lens at a good value. So any advice is greatly appreciated.
