Originally posted by Joyce Keay Hi, I have the Pentax K-70 with the 18-135 kit lens plus the 70-300 zoom lens. I'm going on a 3-day photo shoot in a few days and the instructor has suggested we take along a macro lens. I don't really want to spend $500 for a macro lens. Any suggestions? I think I'd need to order it from Amazon by sometime Sunday. Thanks. Joyce Keay

The 100mm will let you take those macros further away from your subject, thus avoiding scaring them off or getting your own shadow in the shot plus it's weather resistant.
The 35mm requires you get closer to the subject and is not weather resistant, but it's a lot more portable/light and one of the sharpest Pentax primes. The 100mm is no slouch either.
And if you fall in love with either macro, I'm pretty sure there is an option to buy it used. Macro is a specialization that some photographers love or others rarely use. If you find you love it, I think either of these two lenses are worth their price, but it would be a bit crazy to just drop $400-$550 on either one new without 'test driving'.
