I am so confused. I own a pentax K5 and love my Pentax 50mm prime so much, I hate to take it off for my kit zoom. I am struggling with it though as I find 50 too big for general portrait work, indoor family and looking over the top of babies. I have a few jobs coming up birthography, baby bump, families etc. so would I be happy with a fast zoom for example the 24-50 ranges of sigma/tamron (pentax out of price range). or should I just grab a cheap pentax 35mm for now and wait for the new sigma 18-35 1.8 Art lens to come out in pentax k mount????
Please Help.
