The issue might be lens/camera combo.

15MP on a APS-C is still pretty dense and the 18-200 isn't the sharpest knife in the drawer (of lens in the bag if you get my analogy). The denser the sensor the harder it is on lenses.

Are those crops at 100% or past 100%? Any image past 100% will look unsharp.

In general, I wouldn't worry too much how a photo looks super cropped. As long as it looks fine at the size you want to print (or display on your computer) then it is ok :)

Not sure I quite agree with the "unsharp" look - I had one image where it looked sharp at 200% too -> if you have some really fine contrast and differences occur over 1 line of pixels, then 200% will look quite OK too.

Unfortunately the 18-200 is not the sharpest lens. It has other strenghts though like it's versatility and size.

I would get some new glass. I loved using the 18-200 but it just wasn't sharp enough for me. When they make a super zoom with the sharpness of the 70-200 I will have a field day.

I wish I could add something that hasn't been said but the 18-200 is the overall problem. While yes there's more you can do, the biggest is the glass. If you plan to do some beautiful landscape photos, ditch the versatile lens and get a more dedicated landscape lens.

Try 15-85, about the same cost, less FL, more sharpness performance


X-Pro1 + 18-55 f/2.8-4 OIS + 55-200 f/3.8-4.5 OIS
TS-E 24 f/3.5L II + XF 35 f/1.4 + XF 56 f/1.2
Sony RX100 II + G12

The cheapest route for you to make the leap to L is the 17-40 f/4 L. It's an amazing landscape lens that delivers some crazy-sharp images.

actually the 17-40L is not so "crazy sharp" on a crop model!(there are sharper and less expensive alternatives)
but, yes, even without a filter the 18-200 is not the best for landscapes.

What he said.

It's good to understand the cause of the problems, but unless it's affecting your final output (print, computer screen, etc) then I wouldn't get too caught up in worrying about these imperfections and lusting over new lenses.

Hi Gents,

The crops are at 100% - that is, I cropped them out of the original and show them here at the original resolution (no resize).

One of the reasons I'm getting into this is that I've discovered that doing heavy crops is sometimes resulting in an unsatisfactory image because it isn't sharp enuff. With my pocket camera that I take on things like Grand Canyon rafting trips, I sorta expect this, as the sensor is microscopic and the lens is about .5" in diameter - but I was hoping I could do better with my SLR.

What I was really wondering was whether i would do better with better glass or more megapixels, and it is looking like the answer is Glass..:D The 18-200 is durn convenient, but that would seem to have a price.. I already have a fairly good WA zoom in the Tokina (tho I don't use it as much as I shud), perhaps I should look at something like the 24-105 to cover the "midrange" with better IQ. I would be interested in y'all's thoughts on what is a reasonable (i.e., a kilobuck or less) lens to look at.
In reading the referenced reviews on the 18-200, I can also see that I can improve the CA issue, which has been particularly noticeable in some of my sunrise/sunset shots - maybe I DON'T have to "just put up with it"..;).

Again, thanks to all for your help!

Honestly, I think the images look good. I wouldn't be displeased with the sharpness. You have an APS-C 15.1 MP sensor which pushes beyond the limit of the 18-200. Just don't view 100% crops. As the sensors get better, even the best lenses will struggle to keep up at 100%. No reasonable photographer should expect to print 100% crops.

Unless you are in danger of injuring your lens or the filter is helping you achieve a certain look, get it off of there. Several times I have found images that were not quite as sharp as they should have been was caused by the filter. I recommend doing some tests with your filter to see if it is affecting sharpness at the very least.

Hi Jason,

I will try a comparison with the filter on & off -- but I have it on there because a) I have fairly oily hands and b) "clumsy" is not quite strong enuff, and I REALLY get twitchy cleaning the lens vs the filter..:lol:
