I really don't know how the Sigma Art gets such rave reviews. I don't see how spending $1000 on a lens that works when it feels like it is remotely acceptable to the same people who routinely write about Pentax's lacking autofocus--it is a true weakness, but like...Sigma totally seems to get a pass on the highly questionable autofocus on their Art lenses.

I recall the line at the end of Mystic River, when Jimmy says to...whatever Kevin Bacon's character's name was: "Thanks for finding my daughter's killer. If only you'd been a little faster...." It makes me wonder what the K-1 would be able to do if it had that modern 85!

I plan to!! I will dazzle them with my photos and then tell them the story. :)



I'll be taking it out for a rigorous test next weekend most likely, so I will let you know how that goes!

In a complaint that I'm sure will surprise no one who is familiar with me, I found the Nikon offerings in the 50mm focal length both severely lacking for my newly acquired D850 after just one weekend of shooting both and decided to look at 3rd party options. While I've had a very troubled history with Sigma, I decided to give their Art 50 a whirl because it's reviews are just beyond rave.

I guess all those reviewers were paid off handsomely or something. Or given a functioning unit. Hands down, the copy I got has the most abysmal autofocus of any lens I've ever tested. It misses BADLY on a human subject from 4-5' away. Calibration might help but a $950 lens needing this much work out of the box means Sigma has absolutely no quality control at all. Or heck, maybe this is just how it works. Someone once described Sigma lenses as lens Russian Roulette: "You pull the trigger and hope to get lucky." WOW. Someone else, who has the 50 Art and loves it, told me if I was looking for a reliable lens, this probably wasn't going to be it. WOW. That's one heck of a slam.

So I decided to try out the Tokina Opera 50mm. As you surely know, it's a rebadge of the new Pentax DFA* 50mm f/1.4. It arrived yesterday and I immediately stuck it on my camera to give it a try.

HOLY SMOKES. This lens is great. Just plain great. It rivals the Tamron 85mm I've been using and that one is really close to the Sigma 50 and 85 Arts that are rated by DxO as the "sharpest lenses on the planet." The autofocus is dead on from the box, nailing precisely where I want without hesitation, even at wide apertures. The bokeh is lovely and sublime.

If you have a K-1, this is the lens you've been waiting for. I can't test it on the K mount, obviously, but this lens just makes the D850 sing. On the other hand, it kinda makes me sad because if Pentax could have just put out a few more lenses like this, it would have been enough to stay with the brand. I do hope that they can continue to make products like this.
