I would like to photograph small and scared critters, including their eyes and body-parts too.
I am considering a Sigma 150mm f2.8 OS macro lens. I have read about working distance and minimum focusing distance, but I still wonder if a 105mm (better resolution) really could be enough for my needs.
Articles that I read noted that with a 150mm focal length you could be at 50cm from your subject (which is enough not to scare animals), while other articles say that the distance from your subject is somewhat 30cm with this kind of lens.
My questions are:
- Which article is correct?
- How do I select the best lens to photograph critters, insects and so on?
- Is it worth it to work with a 1.4x teleconverter and/or extension tubes and/or Raynox lenses combined with the macro lens?
