Default Tamron Lens

Ok I currently have the 28-80 and the 70-300 Tamron lenses for my Pentax K20. I really like the 70-300 lens and it stays on my camera most of the time. I however have a trip coming up in a little over a month and want to get a good all around lens. I love the Tamron lenses and plan to stay with them. I am looking at the following lenses the Tamron 18-250, Tamron 18-200 and the 28-300. I recently looked back at some of my pics from my superzoom I was using before upgrading to the DSLR and it started at 28mm.

Where I am stuck is the 18-250 going to be a big difference over the 18-200? Would I be loosing that much by going with the 200 vs the 250 on the long end? Then comes the part of would I be loosing that much going to the 28-300? I know on the wide end I would loose the 18 but would the gain be that much more than the 250 or the 200 by going to 300 on the long end?

I am just really kind of lost and want a good compromise lens for my trip without having to switch lens a lot while on vacation.

Hope to hear everyones thoughts and thanks

photographynut-

If you follow the reviews, (like photozone.de) it is easy to determine that the Tamaron 18-250mm and 18-270mm lens have received much better reviews that the older and less reliable 18-200mm lens.

In my opinion, I would be looking at the Tamron 18-250mm and 18-270mm lenses. They are a better bet for you. How do I know? I am a professional digital camera instructor who also likes Tamron lenses a lot as well.

I don't know how much help this will be...When I bought my A300, it came with the 18-70 kit lens. Later I bought a Minolta 70-210, then a Tamron 28-300, then a Tamron 70-300 Macro. I can't tell you when I used the 18-70 last. The 28-300 stays on my camera almost all the time, except when I shoot bugs. I don't use the 70-210 because the Tamron lenses are as sharp if not sharper, and I personally find 28mm (42mm equiv.) wide enough for most of my shots, even indoors.

If you don't need wider than 28mm in a do-it-all lens, you could save some serious money and get a nice all-purpose zoom at the same time.

Sarah is correct about those two lenses, they are both highly rated, and either would give you 18mm on the wide end.

According to your post, you have been using a 28-80 on your pentax. The question I have is--Did you ever wish you could go wider than the 28-80 would let you? That alone may help you determine which lens to go with. Is the extra 10mm worth the extra cost to you? Good luck with your decision, it's never easy, and it won't be the last...

I'm wanting to get a nice all-in-one lens, too. Have decided that for my purposes I really want the 18-250 range. I took my 28-80 on vacation back in May and found there were too many times I'd wished I could have wider. I tend to like landscapes. I have found in my research that the 18-200 isn't a reliable lens. And, for the long end, I always figure having the K20, I can just crop to what I want at that end if needed.

Anyway, my findings. I do have the Tamron 70-300 and find it is my favorite lens. So, Tamron is definitely not a problem for me.

The Tamron 18-250mm is significantly better than the older 18-200mm from user reports and reviews I've seen.

I just purchased the Pentax DA 18-250 which I understand is a rebadged Tamron with the Pentax coatings. The main motivation was a single lens that I could take when travelling. The Pentax was less expensive than the Tamron. The Tamron offers a 6 year warranty, but then again, I've never had a problem with any of the Pentax lenses that I've owned. My only other choice would have been the Sigma 18-250 which has the internal focusing motor (HSM). I own a Sigma 70-300 which is decent, but would not serve me at all at the wide end. Anyhow, here is a sample from my K10D and the Pentax DA 18-250 (Max zoom, wide open aperture, no post processing except for resizing to 900 x 600).

Hawgwild-

I am in the same boat as you are. I have a nice Tamron 28-300 mm lens for my Pentax DSLRs. It does a very creditable job and when paired with the Penrax 18-55 mm lens, you have the field covered nicely.

All you have to do is to go to wwwphotozone.de and you cane see for yourself. Tamron has managed to do a better job, rather clearly.
