Standard Zoom LBA....

I just received a DA* 16-50mm second hand. I bought it as a mate to my DA*50-135. I also own a Sigma 17-70 f2.8-4.5, the Pentax 18-55 kit lens and a Tamron 18-250mm. As you can see, I have a lot of overlap in range. The 16-50 seems to be a fine copy but the other 18-250 and the 17-70mm are also decent copies. And the 17-70mm has decent pseudo macro that is nice since I do not own a Macro lens at this time.
I am wondering if anyone owns all of these lenses and feels that they are all needed for their intended purposes. My initial reaction is to sell one of the 4 and buy the Tamron 90mm macro.

opinions are welcomed!

If you're keeping the 17-70 only because of the semi-macro, it would make sense to sacrifice this one to buy the 90mm. (I wouldn't keep the Sigma either, to be honest)

Thanks Kevin. I just decided the same thing. The quality of the 16-50 and the pics I have taken so far with it have led me to list the Sigma for sale. Just hope the SDM holds out. It is a fairly new lens with 2 months of warranty left. I will keep the 18-250 for travel....

thanks!

Keep 16-50 and 50-135. Sell all others.

What he said. Unless you are shooting professionally and need a lot of back up equipment, you will find yourself frustrated with the image quality of the lesser lenses over time and end up shooting less with them anyway (at least that is the way I found it). My 16-50 is my most used lens, followed by the 50-135. I love primes, but the flexibility that zooms offer is great and these two offer great image quality as well (and truthfully, they aren't that big either).

Thanks for your input.
I have decided to keep the 16-50. Sell the Sigma 17-70 and keep the 18-250 as a vacation lens. I have rearranged my lenses to be almost all Pentax now and I am really liking the colors that the Pentax lenses produce vs the Sigmas. I know the 16-50 is larger than the others but I still have the 18-55 if I need small.
I was in Florida last week with the Sigma 17-70mm and my KX. It was my first time traveling with the KX and I was very suprised at the low light/high ISO capabilities of the KX. With the extra stop at the long end, the 16-50 should be even better..... I might make the 16-50 and the 50-135 my domestic travel kit in the future....

Also consider a Raynox 150 for use with the 18-250 as a way to get decent macro capability out of what you already have without needing a separate lens just for that purpose. Unless macro is really important to you, in which case having a real macro lens certainly makes sense. But if you've been happy with the 17-70 thus far, the Raynox 150 on your 18-250 will absolutely blow it away.

You know Marc, I tried a Raynox 150 about 2 months ago and had horrible vignetting with it and returned it. I was probably doing something wrong. Do you think it would be worth trying another one?

On which lens were you using it, and at what focal length and aperture? If you check out the Raynox Club thread in this forum, or just search around for other discussions of the Raynox adapters, there is quite a bit of info out there on which combinations vignette and which don't.

You can sell the 18-55 but it won't get you a lot closer to the Tamron.

And note that warranties are only for the original owner, so I hope he will help you out if needed.

I was using the 18-250mm. In fact that is why I bought the Raynox 150. Was trying to use it at around 100-135mm. I will do some more research before ordering another one.

thanks Marc....

Agreed, and +rep.

If I only had two lenses, I'd have to stick with these two. They're ragingly versatile.
