Further readings for the Pentax smc D FA MACRO 100mm F2.8 WR
To provide photographers with a broader perspective about mobiles, lenses and cameras, here are links to articles, reviews, and analyses of photographic equipment produced by DxOMark, renown websites, magazines or blogs.
The Samyang 85mm F1.4 AS IF UMC is a high-speed manual focus lens available in a wide range of mounts, including Sony A and E, Fujifilm X, Micro Four-Thirds, and Pentax K, as well as the expected Canon EF and Nikon F options. Offering a wide f/1.4 maximum aperture, and as a 130mm equivalent on an APS-C format camera (such as the current Pentax DSLRs), the Samyang 85mm is an ideal lens for low-light indoor sport and outdoor photos.
If you’ve outgrown the standard kit lens for your new entry-level DSLR, a second lens can add a new dimension to your photography. With a plethora of options available, picking out the right one can be a bit of a minefield, but our best lenses review is here to help. We round up here the big talking points on the 39 lenses that our technicians have tested on the Pentax K-S1.
Although the Pentax K-5 II and K-5 IIs have now been replaced by the Pentax K-3, we’ve analyzed the two models with a range of lenses from both Pentax and third-party makers and thought the results would be of interest to our readers. The information is available online but we taken the opportunity to offer a brief overview of the best performing models. Read on to see how well the lenses perform together on the two cameras.
You have listed this lens as having a "sharpness" rating of 10 Mpix on the primary tab. However, a quick analysis of this chart reveals that the darkest green is no more than an 8.5 on the scale you provide. Further, this lens' sharpness data differs dramatically from other Pentax Limited lenses on the K-3 body, leading me to assume that this particular chart itself is in error.
Please correct this mistake, for it casts a shadow on the overall accuracy of your data.
Based on what ive read lenses with stabilization built in tend to be more effective though. I took a photo with my friends canon 7d 70-200mm F2.8 II lens in a dim lit office and was shocked that a photo came out sharp hand held at 1/6 sec shutter speed.
Pentax D FA MACRO 100mm F2.8 WR/Cannon EF 100mm F2.8 L IS Usm
Just had to comment on this comparison. I have the Pentax . I read many reviews about the lens, many commenting about how expensive it is. However, in comparing this lens to the Cannon, one fact seems clear: it compares quite favourably. But two factors clearly favor the Pentax: firstly, the pentax barrel is constructed of high quality aluminium, while the Cannon is plastic. Good plastic, but plastic. Secondly, the Pentax can be purchased for around $650.00; the Cannon cost nearly $1000.00. Much of the difference in price can be explained by the fact that the Cannon has the USM nearly silent focus motor, while the Pentax is screw drive. Furthermore, the Cannon lens has image stabilization built in, while the Pentax IS is built into the camera, essentially making IS available for every lens attached to the Pentax body. But the bottom line is that the performance of both lenses is quite similar, but the Pentax cost about $350.00 less. Just an observation.
