phoenix15: I am confused between new SDM and DC motor now. Which is superior ? 150-450 is using DC, 70-200mm will use DC also, but then this 24-70 is SDMMy opinion, disregard to the past traumatic syndrome, SDM is better to spell.
I don't think any of them is superior, but it might have required a lot of redesign of the lens to use DC motor.
Tamron USD motor might be same type of motor as Pentax SDM.
rtogog: Am I wrong? Is this not a Star lens? This lens looks identical to Tamron lens which is good performer too. So, will the star lens still in design ? Or Pentax play in affordable FF lens? Will they also re-badge the Tamron 70-200? BTW, this will give more option for us. Thanks
The 50-135mm lens is a Pentax design, and rebranded by Tokina.
Many other Pentax designs was rebranded by Tokina (FI 16-50mm, 100mm macro, 10-17mm fisheye)
KZMike: VERY IMPRESSED. . . finally a vari-angle screen+ weather seals+time lapse. . .specs are looking like this 'rig' ought to be a good sales producer. At first glance I am not sure what " can produce 4k video from stills " is about. . .?
"Supportive shooting functions:" . . . is this similar to Oly's 5 axis stab. sys. or ?
Olympus pretty much copied Pentax design on stabilisation design. Pentax had free floating sensor by magnetics years before Olympus started to use it in their 5-axis stabilization.
Supportive shooting function is for instance.- Composition adjustment, where you can move the sensor to fine tune composition when camera is used on a tripod.- Horizon adjustment, where the camera automatically correct for tilted camera so the horizon will end up in level on the image.
nicolaiecostel: The aperture is not equivalent for anything, it's a fixed value. The DOF equivalence is a different thing.
People thought that if Pentax brings a cropped MF sensor to the market, in a oversized DSLR body, at 2.5-5 times cheaper than a Hassy, Phase One, they found the chicken with the golden eggs. They forgot that MF glass is MF glass expensive and all things MF come at a price.
So here you are, having just spent 5000-8500$ on a "bargain" MF Pentax, wanting to buy a modern, bespoke wide angle and realising you have to shell out 5 grand on either this zoom or that other wide angle they anounced, and that you're stuck with a cropped MF sensor that you can't remove from the camera and use in other cameras, that has 1/125 flash sync and you shoot on SD cards with limited teathering.
Why didn't they put a central shutter in the lens ? It would have been much more usefull than that OS they put in, seen the ISO and the fact that MF users shoot in controlled, stabilised environments.
Pentax has always made MF equipment for field use, which is why the system has the same type of user interface as on DSLR with smaller sensors, weather sealing, and stabilization.
