Pentax 21507 overview

  • 1Description

The SMCP-DA 16-45mm f/4 ED AL Lens is the perfect complement to a digital Pentax SLR camera. This lens covers the popular most basic zoom range of wide-angle to short telelphoto, which is most associated with a standard zoom lens today. The lens provides a focal length which is equivalent to 24-67mm in 35mm terms.

Pentax's DA series feature a "Quick-Shift Focus System" which allows an instant switch from autofocus to manual focus with a slight twist of the focus ring. Coupled with simple, functional design, and the elimination of the aperture ring, the camera's operability is significantly improved.

The image circle in DA-series lenses is designed to perfectly match the 23.5 x 15.7mm size of the CCD image sensor used in Pentax digital SLRs, and thus will not cover the full frame of a 35mm camera. The design contributes to dramatic size and weight reduction, not to mention production costs.

Note: Not recommended for 35mm film or "full-frame" digital SLR cameras

    Pentax 21507 reviews

    SMCP-DA 16-45mm f/4.0 ED AL Autofocus Lens for Digital Camera is rated 4.2 out of 5 by 12.
    Rated 2 out of 5 by from No better than the kit lens I purchased this lens for the extra 2mm on the wide end over the 18-55mm kit lens and also assumed the image quality would be better. Having a constant f/4 aperture throughout the range was nice, but when comparing image quality with that of the 18-55mm kit lens, it doesn't seem worth the upgrade. The build quality of this lens felt about the same as the kit lens. I did some comparison photos using both lenses, and this lens at 16mm wide open (f/4) was much softer looking than the kit lens at 18mm f/4. Stopped down things got better, but still not better than the 18-55mm lens included with Pentax bodies.

    Rated 5 out of 5 by from Excellent zoom! I bought this lens some 6 months before I bought a digital body. It is usable on an AF film body though you'll get vignetting wider than about 21mm. Use it for the artistic effect and excellent wide angle image quality on film!The main impression I have of this lens is the concentration of tone and image. Gradations are captured well, and there's lots of detail (while not quite as much as the 43 Limited) rendered in a very natural way. It does wide angle in an exemplary way.It is very flexible in use- I too appreciate the close focus ability - and covers a very useful range. Negatives: it gets longer as you zoom wider, and interferes with the pop up flash. The f/4 aperture causes AF hunt in dim surroundings. The lens is a bit large. That's it. Expertise: Long term amateur Problems Encountered: Especially zoomed wide, interferes with the pop up flash. You'll want a hot shoe flash or something similar to counter this.

    Rated 4 out of 5 by from Sharp lens Purchased this lens as an alternative to the 18-55mm kit lens and its a marked improvement. I use it mainly as a walking around lens and it works great. Vignetting is kept to a minimum at its widest end and overall sharpness and color saturation is very good. By no means a macro lens - it focusses pretty close as well The build quality seems OK but is not its strong suit

    Rated 5 out of 5 by from Quality with economy For architectural work I needed a wider view than the kit lens provides. To my happy surprise, the DA 16-45 exhibits minimal barrel/pincushion distortion and satisfies my requirements. Color and contrast are excellent, even under severe lighting conditions.

    Rated 4 out of 5 by from Good quality for a zoom, a bit bulky I bought this lens to have a walk-around lens for my Pentax K5. I normally shoot with fixed focal length lenses but sometimes the convenience of a zoom is nice. The focal length covered by this lens is very useful, and while there are some inevitable trade-offs, the image quality is very decent for a zoom. What I was somewhat surprised about is the size of the lens. GIven its relatively modest maximum aperture, I expected something a bit smaller. It is frankly not very balanced on the K5, and becomes extremely long when zoomed to the widest setting.

    Rated 5 out of 5 by from Very good optics. wish it were longer I really like the quality of the lens. Very good contrast, sharpness and color rendering. People allways comment about the saturation and color with photos taken with this. I also own a 24-90FA and this lens does better in the overlap range. I also find it to be much better than the kit lens (18-55) Build quality is good, not great. Only drawbacks 1) Wish it were longer 2) the lens will shade the internal flash.

    Rated 5 out of 5 by from Great Lens This is my walk around lens. I have it on my camera 90 percent of the time. It produces excellent photos and great color. I have other lenses in this range but always seem to use this lens.

    Rated 4 out of 5 by from 1st class optics but 2nd class built Pentax did their homework with this lens and it is very sharp wide open, except at 45mm it is not as sharp. If it were better built, the performance might be even better, but then this lens is rather affordable too.
