Tamron 18-200mm F3.5-6.3 AF XR Di II LD Aspherical IF Macro Review
tamron_18-200mm_spny.jpg
After nearly eight years of using this lens with three digital bodies and with a 1.4x converter on a film body, I thought it only decent to add my $0.02 worth here. Now that it appears Tamron (like all the rest of the current third-party lens suppliers) is moving away from offering lenses in KAF mou...

Sigma 100mm 1:2.8 Micromacro YS System focusing Review
sigma100.jpg
This 100mm Macro belongs to a very peculiar family of Sigma's YS-lenses. Judging them by sharpness and such make no justice to them as their fanciness is more in intriguing versatility of fystem focusing for example. Indeed, there are two focusing systems present: First is the big focusing ring - a ...

ALBINAR Auto 2X TeleConverter Review
IGP3989.jpg
I got the Multi-Coated version without A-contacts of this one as part of a set. I only used it a few times on film, with results ranging from "kind of OK" to "outright horrible". But I did a series of test shots on the K-5 lately, comparing it to the F 100mm macro and the DA 50-200mm WR. You can see...

Samyang 8mm F3.5 UMC Fish-eye CS II Review
samyang_8mm-F3_5_fisheye_CS2_front-nikon.jpg
I like the uniformly curved distortion, there's clear detail up to the edge of the frame. Sharpness is quite good, although I don't really know what to expect from a fisheye. At f5.6 there's only a little blue/yellow CA but nothing bad at all. Contrast and colors are fine, but it's not a HD limited...

Sigma 35mm F1.4 DG HSM (Art) Review
sigma35mm_f14.jpg
I fell in love with that marvel once I mounted it onto my K-5. The purpose of that lens was to use it as a daily lens on a new K-1, which I have to buy yet. The performance with the K-5 is just brilliant. I took several shots and can see the image is sharp from f/1.4. Colour rendition is just as ...

Adaptall - PK (third party/clones) Review
ad-pk-clone-2.jpg
I was pleasantly surprised at how well these were made and worked. For DSLRs, it's less hassle than the offical P/K adapter, which has to be set up just so to get the aperture simulator working. For film cameras, it makes it a stop-down metering lens.

Sigma 28-200mm F3.5-5.6 Macro Compact Hyperzoom Review
user27434_pic110058_1497993919.jpg
I am reviewing a copy of the lens marked "Aspherical IF" on the zoom ring, "Sigma Compact Hyperzoom" on the front, with aperture ring and no DG labeling. This lens is quite small for its 'hyperzoom' type. At first blush it takes images comparable to my HD 55-300 but with less bulk, much faster (and ...

Vivitar Series 1 13mm f/2.8 ED AS IF UMC Review
user73994_pic94542_1450549856.jpg
I may have gotten one of the last new copies of this lens. When I purchased my K-1, I also wanted an ultra-wide and saw good reviews (fenwoodian here included). I saw one listed in the K mount on ebay and purchased it. Right after that, all listings disappeared (I also had difficulty with the suppli...

Tamron AF 17-50mm F2.8 XR LD Aspherical IF SP Di II Review
SHOT6248.JPG
I've had this lens for about three years now, and was my first upgrade from the kit lens. Comments have been made regarding the build quality but I've felt it has been robust enough for my needs over those years. The image quality, contrast and AF are fantastic in good light. Thankfully in Australia...

Fujita 135mm F4.5 Review
Fujita_small.JPG
Recently got this tiny lens. Altough it makes non sense to compare it with some great lens that exist in this focal lenght, it has pretty decent IQ, is sharp enoug stopped down and with very low light fall off in the corners. The handling is not so good (at least in my copy). As the aperture control...
