Hi Colleen
Quite frankly I was utterly amazed to view your statement that:
Quote: I read about people who got the 18-250.........finding that it was too heavy and bulky to leave on all the time.
If you'll forgive the parlance, I have never heard such a load of utter 'hogwash' in my life and can only imagine that this contribution was probably written by 6-stone weakling ! It's a real pity that there isn't a photographic store in your local neighbourhood who have the Tamron/Pentax version of this lens that you could try out first !
Nevertheless, I utterly agree with TomInJax's sentiments when he said:
Quote: I have the Tamron 18-250, and it isn't heavy.......it's a perfect all around lens. And - the results are absolutely amazing ! It isn't one of those "compromise" lenses. It is a truly great travel lens. It doesn't have t he resolution of a fixed lens, but it is very, very good ! I think that you will love the 18-250 lens. You won't regret it !
You said yourself:
Quote: I often am shooting kids and pets who are far away one second... and then all up in your face the next. ...and I got thinking about sitting on the dock at the lake and being able to take great photos across the lake... but not of the kids right beside me.
That's what zoom lenses are all about.....capturing those special moments, not constantly swapping lenses over all the time !
Do the maths and simply factor in the additional cost of purchasing and then carting around all those heavy individual lenses you would need to cover the optical range that the Tamron/Pentax 18-250mm zoom does !! In my humble opinion, the 18-250mm really is a 'no-brainer' decision for many photographers and even my wife is happy to use my K10D/Tamron on occasion.......
case proven ! For what it's worth, I think you're worrying about nothing at all......just my 0.2 cents worth !
Best regards
Richard
