DPPMetro: hahaha, no Pentax mount again. Basically now even the industry is speaking up and saying the brand has no relevance anymore.

Yes, sad times.. they need to get rid of horrible pricing policy and give us some proper K3 successor. K1 is nice, but without lenses comparable to competitors it is not able to compete.

K MOUNT NEEDED for Pentax. K-1 will be nice tool for this lens.

iudex: Wow, this is a real Behemoth!
But this is the trend, set by amazing Sigma Art lenses and Pentax cannot stand aside if it wants to be taken seriously. Top optical results require a lot of heavy glass, 36+ MPx sensors are demanding and the times when a nifty fifty had 6 elements (Pentax DA 50/1,8) are gone and if such a lens came every reviewer would tear it apart.
I sometimes wish my tiny 15mm Limited was a bit sharper and had better microcontrast. But when I see the size and weight penalty it would cost I better accept the outcome from a pocketable 170g lens.
So the best way would be making optically perfect, but big and heavy lenses as well as lenses aimed at small size and weight. So basically continue with the Limited range (which seems to be forgotten nowadays).

FA50/1.4 has resolution when aperture is closed to F4-F5.6.

Last ambitious pentax 50mm lens was that silver A50/1.2.

Anyway FA50/1.4 is just cheap fifty. If they wanted something better, it would have been named FA*50/1.4 and have better chars.

I have that lens. For many years. F1.4 setting was usable maybe on film and K100D. On modern hi-res digital it needs to be closed down at least to F2 to provide something and at least to F2.8 to show details.

On the other hand there are 50mm lenses that are usable straight from the F1.4 setting and are excellent from F1.8.

NO.

High resolution and telecentric design require more corrective elements.

Less elements have better 3D pop and light transmission resulting in better colors. But FA50/1.4 is obsolete cheap 50mm lens that never had high ambitions.

John C Tharp: By the size, it looks like they could have just rehoused Sigma lenses in WR shells like they did Tamron's- and that wouldn't be a bad thing!

Sigma is different lens and there is no collaboration between sigma and any other company.

Only tamron does that stuff.

Nikonsyncro: One of the reasons I don't own any Sigma lenses.
The Zoom turns in the opposite direction.
When working under pressure and things must happen there is no time to think of the lens mounted and the direction you must turn the zoom ring. It must just happen.
Nikon user. But I am deffnately going to try the 135mm

LOL.. "Opposite direction"

My pentax lenses are turning also on the other way than my sigma lenses and IT IS NO PROBLEM AT ALL.

photoOregon: Too bad they (Sigma) doesn't care about Sony's A-mount cameras any more. I would have loved to try the new Art lenses.

Even worse for Pentax, which has way more cameras on market with K mount than Sony has with A mount.

On article Throwback Thursday: Casio QV-4000 (59 comments in total)

I have CASIO QV-R40 which also was 4Mpix camera.. but using "best shot" mode editor it was possible to "install" new "best shot" profiles and gain full manual control over shutter (1/2000 to 2s) and aperture (two steps). Wonderfull little camera that took something over 30 000 photos before the aperture/shutter died. Now only video (320x240 no sound, 30s duration) works. Photos are stuck on something like 1/10s by electronic part of shutter.. mechanical shutter is dead. Anyway it was cute camera and the lens had plenty of contrast.

In reply to:

kaiguy: Odd that they went with the 500mm f/4 as their first supertele...maybe because it's geared towards non-professional birders? My understanding is that the 600mm f/4 and 400mm f/2.8 vastly outsell the 500mm f/4, but the 600mm/400mm I guess are likely to be sold to professional shops who are 100% Canon/Nikon.

First supertele? Nice joke.

They already had 500/4.5 for ages.

Not to mention 300/2.8, 300-800/5.6, 200-500/2.8 and others like 50-500, 150-500, 150-600 etc.
