Pentax smc DA 40mm F2.8 XS Lens

The Pentax 52 mm Lens Hoods for Pentax DA Lenses, are designed to not only protect the DA Series camera lens of the from fingerprints and dirt, but can also prevent glare and lens flare. These easily mount in front of the lens and offer physical protection.

The Pentax Limited DA lenses aren't for everyone. If you are a personthat considers an f/2.0 lens as borderline slow, you will see theglass ashalf empty. However, if you are a travel or adventure photographer whoappreciates diminutive size and robust build you may be inlove. Despitethe criticisms they receive, the DA Limiteds are not particularlyslow, butadmittedly they aren't particularly fast either. In truth, it dependson what youare comparing them to. When compared to ultra fast primes they seemslow. However, a better comparison would beto a 28-105 f/2.8 zoom, which is essentially the range they cover inthe35mmformat. The 21mm is only 1/3 stop slower, and the 40mm is f/2.8, whilethe 70mm gets you to f/2.4. When looked at in that way, are theLimitedlenses really that slow? In addition, theLimited lenses are much easier to handle, lighter, and less obtrusiveininformal situations. I believe Pentax made the DA Limiteds as fast aspossible without adding size or compromising the optics. When youcompare the Pentax Limited 21mm f/3.2 to a Sigma 20mm f/1.8 EX, it'sobvious whata feat producing a near f/2.8 lens as small as the 21mm was.

2011: Pentax 01 Standard Prime.

The build quality of the Pentax lens is very high thanks to quality materials and tight build tolerances - this positive impression is actually typical for the majority of the Pentax DA lenses. The lens uses a duo-cam system (2 inner lens tubes) to extend when zooming towards longer focal lengths. This may sound a bit worrisome at first but the tested sample showed no significant wobbling whatsoever here. Both the broad, rubberized zoom control ring as well as the smaller focus control rings operate very smooth. The lens has an internal focusing system (IF) resulting in a non-rotating front element. The Pentax Super Protect (SP) coating on the front element has been optimized to repel dust, water and grease.

The Pentax DA SMC 17-70mm f/4 AL [IF] SDM is undoubtedly the most desirable standard zoom lens in the current Pentax lens lineup. The resolution characteristic is very good without any significant weakness. The vignetting and distortion are about average for a lens in this class. The lateral CAs are relatively well-controlled although you may spot some traces in field conditions when using wide-angle settings. The quality of the bokeh (out-of-focus blur) seems to be very fine albeit limited compared to fast prime lenses naturally. Contra-light situations are handled fairly well with comparatively underdeveloped ghosting problems. Typical for most Pentax DA lenses the build quality is on a very high level. The fast and near-silent ultrasonic AF is also a very welcome new feature. All-in-all a very harmonious package."Ad ID:
