BestBuy has this combo for $1599

I just ordered the camera BODYfrom RITZ with the new 18-250 Sony lens for $1900 !!

Is the set-up with the newer lens WORTH the $300 difference?

I've got the 18-200. It was the first lens I bought for my KM5D. I now own 8 lenses (6 purchased used.) The 18-200 is now the dimmest lens with the most distortion that I own.

All indications are that the 18-250 is a vast improvement over the 18-200.

I think you should stick with what you've got.

Thanks TCav,

I'm beginning to agonize over this. 300 bucks is a nice piece of change.....


Whan you say, "dimmest lens with the most distortion that I own."

Do you mean it has gonr sour or that your other lenses are outperforming it?

My other lenses are outperforming it. The 18-200 is junk, and has turned me against all superzoom lenses, but the 18-250 is the best of its kind.

I now have several lenses that, in total, cover the zoom range of the 18-200 and more, and each and every lens does a much better job within it's range than the 18-200.

But the Sony 18-250 is a rebranded Tamron 18-250, which has received universal acclaim.

Keep the 18-250. Steer clear of the 18-200.

Good Luck.

One difference between the Tamron 18-250mm and Sony 18-250mm lens you should be aware of is that the Sony appears to be geared to focus faster than the Tamron from reports I've seen.

There are less turns of the focus screw from close to infinity with the Sony (it's using different gearing). User reports I've seen say that this does not impact accuracy, but does make the lens focus faster. Apparently, the Tamron needs 21 turns of the focus screw from close to infinity, and the Sony uses 12 turns from close to infinity.

IOW, the lens you want out of these choices is the Sony 18-250mm.

Thanks for that information Jim. Are you pretty sure? I would think (shame on me) that if the 18-250 is, indeed, a Tamron branded for Sony it would be identical except for the logo. NO? I can't seem to locate side-by-side specs.

The Tamron is 60 bucks cheaper. In some ads (as Tamron)it's called a MACRO and others it is not. http://www.abesofmaine.com/search.do

I too, purchased the A700 and the Sony 18-250 from RITZ and can't even locate the Tamron 18-250 there.

Again, I apologize for agonizing over this, but I shouldn't even be buying all this stuff. I've been out of work for most of the year!! I'm a dumb butt that needs a new toy.


Oh yea - the Tamron also ships with a lens hood.


Thanks - more input appreciated.

There is another thread going on right now debating this issue. Chances are, unless you're changing focus distance a lot, you may not notice as much difference (because if a lens is already focused at approximately the same distance between photos, the focus isn't going to need to change as much).

I've also seen it reported before that Sony uses different lens coatings compared to Tamron branded lenses, too. I don't have either lens. So, I can't confirm that.

P.S.

B&H stocks both of these lenses now (and the Sony branded lens does include the hood).

Sony 18-250mm at B&H

Tamron 18-250mm at B&H

Personally, I avoid Abe's of Maine (I noticed you mentioned that vendor in your posts above):

It's clear to me that the the 18-250 is better than the 18-200, and that the Sony 18-250 is at least as good and probably better than the Tamron 18-250.

I think you're getting the best deal on the best products. It's ok if you want to stop agonizing of this. [suB]:-)[/suB]
