Weird, I just went through the Sigma lenses, I've often felt that 3rd party lenses offer good value for their money , 26 pages of combinations tested, all on Nikons and Canons, not one tested on a Pentax. It's nice they posted what they did for Nikon and Canon users, I'm not seeing much of interest.
So their top rated lenses Nikkor105, SOny Planar 85, and Sigma 85 1.4 in third place. Now I can order the Sigma 85 from my favourite on-line camera store for a little over $1100, but, it's not tested on a Pentax. Why not? What good are lens ratings if they are not inclusive? SO question, what would the rating of a Sigma 85 mm F 1.4 be if placed on a K-5?
I recently blew a chance to purchase a Pentax FA 100 macro, second hand, so I thought I'd check it out, see what I missed. It's not even on the list of tested lenses. From the look of it, most of what they've tested from Pentax appear to be kit lenses. it looks like most of what they tested were about 5 lenses on 3or 4 different bodies. It's too bad, because I'd really like to know how the Pentax 100 macro stacks up against the Nikkor 105. You won't find out here. I'm not saying their testing is bad, I am saying it's woefully incomplete, way too incomplete to be drawing real comparisons about what the best lens and camera might be.
Without the help of the lens manufactures, ie, giving them some lenses to test, this is never going to e an important feature of this site. And testing a PENTAX DA 16-45mm F4, Pentax SMC D FA 50mm F2.8 MACRO, an 18-55 kit lens, and a few slow 50-200ish zooms, on a K-20D, a K10 D and a Km, how is that any kind of a test to determine which Pentax lenses are rated highest? Lets just hope it's a work in progress.
Did the OP know what he was posting?
I am appreciative of the heads up on the Sigma 85 1.4 though. Anyone know anything about it?
Quote: I guarantee you you're going to get a lot of replies about DxO using arbitrary metrics and technical meaninglessnesses that undervalue Pentax lenses relative to their competition.
It is ironic, because everybody was wetting themselves about the K-5 edging out Nikon and Canon's rigs in the sensor tests.
Ready to recant? Or do think comparing Pentax kit lenses to other's primes is a good test?
