Tamron 18-200mm vs DAL 18-55mm

Hi!

I am new in the dslr world. i am living here in the Philippines. I have a tight budget of around $300 for a new and all around lens. I need an all around and general purpose lens as I am still in the process of learning the art of photography. I don't want to always change lens during shoots to minimize dust and accidents or other unfortunate event that the camera might befall. I looked up some reviews and prices of lenses in the market. I found this Tamron AF 18-200mm which is sold at around $230 (b&h, adorama, newegg etc.). It quite has good reviews from online sources and in the forums. Now this is sold here in the Philippines for around $300 and I am now almost convinced in purchasing this lens. However, I also have some questions that need to be answered.

1. Is this lens an upgrade or a downgrade in terms of IQ compared to my kit lens (18-55mm)?

2. What lens can you recommend that is an all around and general purpose lens (wide to tele zoom) besides the Tamron AF 18-200mm in the working budget of $300? First hand review or online reviews of such product is very much welcome.


Thanks,

Rodyl

Most would say the 18-200's are not as good as the 18-55, but the more expensive 18-250's are. But that's not to say you can't get decent pictures out fo the 18-200. If it's that imporant to not have to change lenses and you don't want to spend more than $300, then that seems to be your best bet.

Thanks marc! So it would be a downgrade in IQ compared to my DAL 18-55mm. I was interested with the 18-250 but it was too expensive about double the price of the 18-200mm.

I have got a follow up on whether a Tamron AF 70-300 be a better buy to complement my kit lens? its cheaper and reviews (photozone and ephotozine) show it has a better IQ than the 18-200mm. I think I can live with that compromise of having to change lens if it means saving up money and gaining IQ at the same time.

I second Marc's comment. The DA18-250mm that is a rebadged Tamron 18-250mm is highliy regarded and far superior to the 18-200mm. The DA18-250mm is the ideal all-rounder lens. There are a few 2nd hand Tamron 18-250 and Pentax 18-250 around, but the prices are not really cheap (~$350).

I wish that was true here in my country. There aren't much used or 2nd hand Pentax mount lenses here. And buying a new Tamron 18-250mm ($650) is just out of my budget.

Rodfs,
Like you, I could not find well-priced DA18-250mm in my country. I bought my DA18-250mm 2nd hand through the Internet at www.keh.com. The lens was like new. www.Adorama.com has also some 2nd hand lenses. Both adorama.com and shareasale.com/r.cfm?b=889257&u=523490&m=66875&urllink=keh.com are highly respected 2nd hand places and their prices might be higher than on the rest of the Internet. Off course there is also e-bay and www.pentaxforums.com (Marketplace).

I noted that there were a few more 2nd hand Tamron 18-250mm than DA18-250mm available in the last couple of months, but I agree that the marketplace is limited.

Keep the kit lens and add a DA 50-200mm. It's cheaper too.

Like I said, the 18-200 might be a donwgrade, but maybe not enough to matter, and if you're really concerned about changing lens, that could still eb the way to go.

Betwene the 50-200 and 70-300, I like the smaller size of the 50-200 better, others like the greater reach of the 70-300 better. Optically there's basically no difference to speak of. In my tests, I find the 50-200 at 200mm cropped to provide the same images as the 70-300 at 300mm looks about as good or even better, but others find the opposite, and in any case, to see differences, you need a magnifying glass, so it's really not worth worrying about.

Thanks for your input guys! I really appreciate it! I might be taking the 18-200mm route then purchase maybe come christmas time (when i've got the budget) a prime or maybe a Tamron 28-75mm.

I would also like to add the Sigma 18-125 into the mix. Is this lens as good as the Tammy 18-250? Reviews have been quite good. Hope to hear from you guys.

There are 2 Sigma 18-125mm: Sigma 18-125mm f/3.5-5.6 DC and Sigma 18-125mm f/3.5-5.6 DC HSM.

From your posts, you are likely looking for the former. The following reviews might be relevant:
Sigma AF 18-125mm f/3.5-5.6 DC (Pentax K) - Review / Lab Test Report
and
Sigma Lens: Zooms - Sigma 18-125mm f/3.5-5.6 DC (Tested) - SLRgear.com!

Generally, the Tamron 18-250mm/Pentax DA18-250mm are considered the best in their category, and the extra range over the 18-125mm is welcome if you want to use a single lens.

Hope that the info will help.. and Happy Easter.
