Hello everyone,
I am looking to acquire my first macro prime lens, as macro photography has been attracting me more and more these past years. I currently have the possibility to purchase either the Sigma 70mm f/2.8 EX DG or the Pentax D-FA 100mm WR for the same price.
My current setup is the 15mm Limited for landscape and the Pentax F 28mm as a walkaround lens. I also have the Pentax M 50mm: it was the first lens I bought apart from the kit lens but since I got the 28mm, I find the 50mm either too long, or too short as a telephoto. Last holidays I took, it only served for 1% of the shots over 700 so I'm thinking of getting rid of it...
Concerning the macro lenses, I was originally more attracted to the Pentax 100mm, but the Sigma 70mm seems to better complete my setup if I also want to use it for candid portraiture outdoors, for architectural details or telephoto landscape. I'm afraid the Pentax 100mm would be too long for those purposes and that the gap between my 28mm and the 100mm would be too important.
On the other hand, the Sigma 70mm seems huge and heavy in comparison with the 100mm, and I fear it would be too short for the macro use I'd like to give it (which is the primary goal of that acquisition!).
Thus my questions:
- Could the Pentax D-FA 100mm WR be easily used for other purposes than macro? I found in other posts various examples of portraits and telephoto landscapes taken with this lens but wouldn't the gap between my 28mm and the 100mm be frustrating?
- Is the Sigma 70mm f/2.8 EX DG long enough for macro photography of bugs? Not necessarily dragonflies or that kind of flying little things that I know are easily afraid, but mostly the crawling bugs that wander around the vegetables in my garden
And are the weigh and size of the lens a real bother as a telephoto lens ? I don't mind those criterias as a macro lens, but if I had to carry the lens through an entire trip as a telephoto, it would definitely hold me back.
- And one last completely subjective question, if given the choice between the two of the them, which of those lenses would you have?
Thanks a lot !
