Sigma 18-200 vs Sigma 17-50 & DA 55-300 PLM

I am looking into upgrading my kit with the Sigma 17-50 f/2.8 (replacing the kit lens) and the DA 55-300 PLM (replacing my other kit lens, the DA 55-200).

But... I saw a lens for sale locally that got me thinking. It's a Sigma 18-200mm f/3.5-6.3 C Macro OS HSM for $250.

That lens could kind of replace both my kit lenses for a fraction of the cost. It is rated at 9 on our review pages... but there is only one review. And of course I wouldn't be getting nearly the quality of lens as the 17-50.

My question to you all: Is the savings worth it? I estimate the cost of the other two lenses to be about $800 if I can get one of them used, so I would be saving ~ $550.

Is compromising on image quality, speed, reach, and focusing speed (especially at the long end) worth the $550 savings to you? Do you value the versatility of a single lens? This can certainly be a tough call, but we'd need to know more about your shooting style and needs to be able to make a good recommendation.

In the absence of other information, from my perspective the only thing you'd be gaining by upgrading to the 18-200mm from your current setup is silent AF and the convenience of just using a single lens. The image quality would remain similar, whereas with the other two lenses you'd be paying a premium to bump up the performance across the board.

Also, it looks like that 18-200mm is long overdue for an in-depth review! We recently did the 18-300mm "C", but not the 18-200mm.

The one review that we have on the lens review page makes this lens sound a lot better than the kit lens, but I am not too trusting. An in depth review would be great!

Go for the two lenses, the image quality will be noticeably better.

Even the 55-300? I know it's a little better but it's still the same optics as the 55-300 kit lens, isn't it?

I replaced my kit lens with the DA18-135mm and it's awesomely good....

for more length, I have a DA L 55-300mm, which holds its own, but also an FA*300/3.5 for work at 300mm...

No, the 55-300 PLM does not have the same optics as previous iterations of the 55-300. The PLM version is particularly strong in the 55 to 200 range, where it comes surprisingly close to some of the top lenses in that range.

The 55-300 PLMís image quality is surprisingly good. Iíve been very pleased with it. But I love the Pentax 16-85. Itís really a gem, although not a f2.8.
