Wanted to get your thoughts on this. I've posted this in the PentaxForums.com as well.
I'm set on getting the K5. But now comes the usual dilema of which lenses to get. I like to shoot street and take candids of strangers. However, I'm not one of those people with internal fortitude to get up and close and personal (although sometimes I will). I also like to take candids during social events, which are typically indoors. Lastly, I also like to take photos during travel, which (other than photos of the local folks and my GF) would also encompass landscape, architecture, and other points of attraction.
My thoughts for now is that I'd like to have at least one zoom lens that could be a good walk around, and one prime that would be used indoors and in low light situations.
I've been debating the following combos, and I'm interested in learning more about your experience with these lenses in combination with the K5 (or other Pentax DSLR's):
18-135 and 43 Ltd - nice, small and light kit; some flexibility with the 18-135's focal length
Sigma 17-50 and 70 Ltd (or 77 Ltd or 100 FA WR) - the allure of a constant 2.8 on a standard zoom; plus the little extra reach on the prime for walkaround sniping or portraits with great bokeh; this would be the least flexible combo as the reach would be most limited, but IQ wise, it might be the best (priciest too)
Sigma 18-250 and 43 Ltd - even more flexible than the first combo and would forego needing a telephoto lens in the near future; BUT the 18-250 is much bigger and chunkier than the 18-135 (and even the 17-50), which is a downer as I am choosing the K5 (over the D7000) especially because it's the smallest semipro DSLR; IQ of the 18-250 probably worse than the 18-135
So these are my thoughts, and I'd love to hear yours as well. I am open for other suggestions too.
Thank you for your assistance!
