Pentax DA 18-250mm f/3.5-6.3 ED AL IF Reviews

Photozone reviews the Pentax DA 18-250mm f/3.5-6.3 ED AL IF and writes;
“Lateral CAs are fairly well controlled except at the long end of the zoom range. The build quality of the lens is up to the usual Pentax DA standards which is a good thing.”
Rating: ★★★★☆

WDC reviews the Pentax DA 18-250mm f/3.5-6.3 ED AL IF and writes;
“There is some chromatic aberration at both extreme ends of the zoom range, but this is not obtrusive in real-world pictures except in the case of demanding subjects such as architecture. In part, the fact that chromatic aberrations are visible is due to the zoom’s high sharpness, which peaks at a very impressive 0.37 cycles-per-pixel.”

User Opinions

Pentax DA 18-250mm f/3.5-6.3 ED AL IF User Reviews

Nice Walk Around Lens | Rating: ★★★★★
“Being new to dSLRs, I decided to purchase this lens for my new K200D. It is a very nice walk around lens and I used it on a recent trip to the Smokies. I was able to take some excellent pictures using just this lens and the zoom telephoto allowed me to take a variety of picts of the same scenery using the same lens. “ – by Big Pecan

Terrific Starter Lens – Very Versatile, nice results, great price | Rating: ★★★★★
“This lens has a solid feel without the weight. Comes with a lens hood and cap. Very intuitive design. Works flawlessly with the Pentax K20D…acceptable speed, crisp clean photos. Since the 18-250mm is effectively 27-370mm due to digital, this is the perfect lens to leave on the camera for those impromptu shots. “ – by javajunki

I bought it for the outdoors | Rating: ★★★★☆
“This lens although a bit slow is very sharp and ideal for broad vistas to tight distance shooting. It has one notable flaw (from my POV), that the barrel twists opens while walking (i tested several & it was a common flaw to all). There is a built in fix, a “lock” switch on the barrel & it works well, but it an extra step each time you stop & go. “ – by paul arbor

Almost prefect | Rating: ★★★★☆
“The manual focus ring is ergonomically well done but mechanically a bit crunchy. With autofocus engaged the manual focus ring is not moveable (I guess this is okay). With the autofocus deselected the manual focus ring seems partially engaged and anything but smooth.” – by Henry A. Lampazzi

Pentax DA 18-250 Zoom | Rating: ★★★★☆
“I’m thoroughly impressed by this lens. The sharpness is great at any focal length even at full zoom. Just a little getting used to in marginal or low light situations. The amazing reach allows me to take pictures that were impossible to take before. “ – by J. Santiago

way better than it should be | Rating: ★★★★★
“As for the picture quality: It is incredible. No super zoom lens has any right to be this good. I thought this would just be my starter lens, a walking-around lens for the time being, but it’s turning out to be the only lens I’ll ever need.” – by Remo B. Wieland

Excellent with a little help | Rating: ★★★★☆
“With the profile for my K20d and this lens loaded in, the plugin does a really good job of fixing both the distortion and the fringing. Now, I’m not just satisfied but thrilled by the lens performance. Yes, sharpness is still a bit better in the middle of the zoom range but still decent at the extreme ends. “ – by Michael McKee

This + In-Body SR = Epic Win | Rating: ★★★★★
“Mount this on a K20D and you’ll have a 18-250 IS lens with embedded MTF chart for Program AE. Then set your Program AE line by custom functions for MTF priority. You’ll get VERY nice images. You’ll not struggle with changing the lens to get a good shot and you’ll not get any dust on your sensor. Of course there are many exceptional lenses for studio shots or specialized shots. But as for general walk around lens, as far as you use it with a in-body SR Pentax, this lens cannot be beaten.” – by Ender Kasm

Fantastic Walk Around Lens | Rating: ★★★★★
“This Pentax version of the Tamron original does JUST what I wanted it for at a very reasonable price. When I go on trips or outings, I want to carry very little. This more than adequately replaces my previous down-sized kit of an 18-55 and a 50-200. Not only is one lens much lighter than two, it takes considerably less space and provides me fewer opportunities to introduce dust into the camera body while I change lenses. On top of that, it produces sharp pictures with minimal CA. “ – by L. Levy
