I've also used two separate Sigma camera bodies with that type of sensor. Depending upon the subject, lighting, and all... I've found that the Sigma SD1, and even the built in lens Sigmas are able to capture better than any of the Pentax 16mp sensors. The Sigmas even come close to the b&w quality of a Leica Monochrom - ouch.

But you are quite correct, the software is some of the worst out on the market.

Unfortunately the chart doesn't show medium format, or where Kodak disc might fit in

I have some 5k photographs with the newer 16-85 already. Whereas... The older 16-50 has failed me twice within two months of purchasing it, and also using it on a very "lightweight" scale.

Even seeing and using the newest off of the line run 16-50... It's just one of those lenses that can NEVER be carried around and used without worry of having it fail completely. The newer 16-85 is build considerably more durably and reliably, although those apertures are sad if not having ideal lighting

B&H prices, the largest photographic retailer in the world. Also similar prices throughout that country and through most of Asia

The aperture of the Pentax 16-50 is considerably better,

The updated optics of the Pentax 16-85 are better, except at the widest most range. The reliability of the newer version is simply beyond compare. The WR of the newer version is also a plus

Both camera bodies either by themselves or with other similar outfits such as lenses... The Pentax K3 not priced below that of the Pentax K-S2. Even at current price levels the Pentax K3 will have considerable further reductions throughout the rest of this year as Pentax Full-frame comes around, and also the imminent release of even a second digital non full-frame body to replace and update the K3

More lens selection; definitely macro options. Sigma has considerably more lenses available outside of what is currently offered in PK.

More flash options. While the two (somewhat) higher end Pentax units aren't hurting all that much for most users (especially with the WR feature)... It would be considerably better to have the option of having the Quantum line (by far the best flash on the market for most any camera) that would also be a dedicated hot shoe.

Regardless of focal length of lens; I'd be sure to put the maximum of neutral density filter in the front of that lens. Cannot begin to begin to mention how many sensors I've seen over the years of people taking photographs with the sun as the subject.

Could be worse though, could be a dslr

Anyone here ever use BitCoin to purchase any type of gear?

Last month alone I generated about 11oo pounds. Although there was also a time when it was 4x that much

I have every single one of the WR lenses except for the 560; the two full frame lenses that have yet to be officially released and also the compact "folding" zoom.

The 18-135 is an incredible bargain at it's existing price and I've never had a WR lens fail due to the weather. Better optically than the three other priced (existing) entry level WR lenses. Not as good optically (or aperture) as the 24-70 limited, the 16-85 (one of Pentax's better zoom lenses), or the three other higher priced models.

The only two drawbacks about the 18-135 are the general terrible apertures of most of the WR line (unless one is willing to pay out the literal price and also the price in size and weight), and that it is not as good optically as two of the existing WR lenses that have been released within the last year
