On New samples from the Sigma 24mm F1.4 DG HSM Art lens article (217 comments in total)

Honestly I'm not sure how focus confirmation is handled in Canon or Nikon mounts. I do know Pentax has "catch in focus" if you enable it, meaning the camera fires the shutter as soon as the image is in focus (there are a lot of manual focus lenses for the K-mount, they have certain features like that for their vintage glass). So while can be very difficult to use MF lenses with lower-end Canon/Nikon bodies using their tiny pentamirror viewfinders and fixed focus screens, there are many MF aides out there if you need them, either as add-on accessories or included features in certain brands. I hear Fuji and Sony mirrorless EVFs are great for that as well.
I'm not trying to say one way is better than the other, but rather that there's no need to write off manual focus completely when some of those lenses (i.e. Samyang, Zeiss, old Takumar primes, etc.) are still so thoroughly good if you have the patience to use them.

Just saying. Even with both accessories, it's half the price of the Sigma and beats both major brands' quality in most ways. This is worth a comparison, or at least a question: How much is AF worth to you if it costs both dollars AND image quality?

Fair, but I do think it's worth noting that more than 100 years worth of society-altering photos were taken with manual-focus lenses, without the aid of live view or image stabilization. I wonder, how many rounds of the Olympics would that be?
I don't mean to sound cynical, AF is very convenient. But it's by no means the be-all and end-all of photography, especially with well-made MF lenses and their focus distance scales and damped long-throw rings.

As far as sharpness, transmission and CA go, the Samyang's the one to beat. http://www.dxomark.com/Lenses/Compare/Side-by-side/Samyang-24mm-f-14-ED-AS-UMC-Nikon-on-Nikon-D810-versus-Canon-EF-24mm-F14L-II-USM-on-Canon-EOS-5D-Mark-III-versus-AF-S-Nikkor-24mm-F-1.4G-ED-on-Nikon-D810___682_963_473_795_310_963

@mais51 They sure are :) They have aperture control for Canon, Nikon and Pentax bodies now, though, so at least you can set the aperture the same way as other lenses. Focus confirmation, too, on Nikon mount.

ManuelVilardeMacedo: I like the fact that Pentax was able to extend its penchant for garish colour schemes to the 70-200 zoom. A yellow, a green and an orange ring! (Though, unfortunately, the latter can't be seen when the lens is mounted on a body.) I expect no less than a full-frame body in gold and pink to match.
Hopefully image quality will compensate for this chromatic exuberance...

I don't think the gold+alligator skin colour scheme did very well for them that last time: http://kmp.bdimitrov.de/bodies/photos/LX_50f1.2_gold.jpg

On More things we found cut in half (CP+ 2015 edition) article (140 comments in total)
In reply to:

brownie314: So, this CP+ is so boring that dpreview are searching for junk cut in half at the show? Worst - CP+ - Ever.

Last year's edition was just about as entertaining as this one, I was happy to see it once again. And no, this is not a testament to CP+ or its entertainment value. This is well-handled knowledge of the factors at play in the foundations of algorithmic science related to what makes people giggle on the internet. "This one can't focus for s*it though. It's been cut in half." HA! Solid gold.
Deep down, you know you'd have been at least subconsciously keeping a mental tally of this if you could have afforded to be there in person.
....at least if you're as simple and easily entertained as the rest of us. BTW, glad to see your avatar doesn't get the yearly swap-out, it's also very entertaining.

LOVE IT. Geekiness and rough humour sprinkled with a hint of doom. I was hoping you guys would make this a running theme. Thank you for that

Lawrencew: So with sensor shift a la Olympus I should be able to get 300mp images :-)

https://www.youtube.com/watch?v=bhTjrCsTIqE As you can see in the side-by-side of the olympus high-res test shot in the last video, at 5:47 in this video the Pentax execs explain these slight sensor shift "high-res" modes greatly increase the file size without actually increasing resolution or image quality.

Skip in to about 2:25 in this video and you'll see why Pentax abandoned the sensor-shift high-res tech before it ever launched in one of their bodies: https://www.youtube.com/watch?v=0uQKYgQaNHQ

In reply to:

star shooter: If this sensor is 120Megs what would its top ISO be...1,000,000? Now that would be something, eh?

Other than that, this sensor would be great for Astrophotography, studio, portrait and landscape.

If it's 120 megapixels, I'm pretty sure its top ISO is about 6.

We are lucky to have clever and inventive engineers.
This is Canon's way of saying, "hey, we're sensor tech leaders!"

BAHAHAHAHAHA you're great. I like you.

@karlwunsch just saying, but keep an eye on this 70-200. They've got a history of killer optics. There's probably a reason it's one of the largest of the lot.

See, it's people like that "Digital Imaging Technician" up there that really bother me. People who act like the MP count is the be-all and end-all of digital photography, without ever recognizing the fact that their high MP counts make every other aspect of their cameras suck. 36MP, but 1.5 fps, three-minute waits for in-camera HDR and 2GB RAW files. Don't bother with "auto ISO"

@karlwunsch I'm a happy Canon ex-user. It bothers me that they're ridiculous because the average consumer only (and ignorantly) cares about MP-count alone, and that's going to affect the better brands' better cameras by default in the long run. Not to mention Canon's ever-flambuoyant CEO, laughing at its own users for falling for it all this time: https://www.youtube.com/watch?v=sJBq0z2Vmu4

Certainly not aimed at anything above ISO 100 or below f/11, either. I wouldn't pay more than $1 for any camera this wang-envy garbage ends up in.

Robert Garcia NYC: Anyone knows why no E mount for Sony?

You could always buy a Metabones Speedbooster EF-NEX adapter and forget any hope of AF performance, but at that point you might as well buy the (optically THOROUGHLY impressive) Samyang 1.4/24.

Weird that they didn't bother putting the new retractable kit lens on their roadmap yet.
*edit* nevermind. Found it.
