I had a 28-135mm but, while appreciating its build and optical qualities, I did not find its weight, focal range on aps or the 1.5 meter nearest focus to my liking. The “macro” only at 28mm I thought pretty useless. Inevitably it spent more time off than on the camera so I sold it.
I’ve managed with the 18-70mm kit lens for those occasions when I don’t want the weight or inconvenience of several lenses – family outings, social occasions and the like. I must say I’ve been very happy with it and results are well beyond its small cost when bought with the body.
Larger prints are very acceptable and, for the purpose they were taken, compare quite well with anything taken with “better” lenses. Naturally this “kit” lens is softer wide open, and there’s more distortion compared with the old 28-135mm, but in the general run of stuff not very noticeably so. Unless, of course, one starts pixel peeping and being hyper-critical. Its certainly much better for general use in size, weight, focal range and close focussing.
