Like you said Jonathan, it's Samsung first sensor so Pentax probable had a lot of influence into that.
Sony makes sensors for themselves and Nikon so Pentax was a small player in that and wouldn't have had a lot to say.
I think that was a main reason for switching.

true focal length, first time I heard that one.
You mean equivalent focal length, right Matt

You already said that almost 2 months ago link

ps. finally found their website link
Someone has an idea how their mirror lenses are?

The one on the first photo is probable Nikon model or something

Here a photo from the Pentaxforum you linked to from the specs of the Samyang



These come from Vivitar site.
Filter Size 72mm (front mount)
Minumum Focus Distance 1.0m (3.3ft)
Focus Control single focal lens
Angle of View 28.3°
Groups/Elements 7/9
Length 71.2mm
Max. Diameter 76mm
Weight 510g

everything is the same except weight and length but are very close.
On the pentax forum they said this
The lens looks surely very good, certainly for that money.

Here is another review that put it against the Nikon lens

For you Martin, the K-mount version link

Seems I'm going to win

Was with opera 10 and I didn't have a problem with the forum.

and this the test with IE7

Interesting difference.

Just wandering who has the problem, Samsung or Pentax?
What was the problem with the K20D who also had lines, was it the sensor that was faulty or something else?
Maybe Pentax should have stayed with Sony...?

Didn't knew that brand, they also made some Vivitar's
Vivitar 85mm f/1.4 Asphereical IF is made by Samyang so is probable the same lens.







Actual all current vivitar lenses are Samyang lenses.
They have a 500mm f/8 mirror lens
800mm f/8 mirror lens
650-1300mm f/8-16

Don't know if the vivitar branded ones are cheaper then Samyang?
Samyang made before that lenses under the name Polar:
800mm f8 Reflex
85mm f1.4 Aspherical IF
So most likely that 85mm is also the same so good luck hunting down which one is cheaper.

Thank you for the info Bob good to know Pentax did something about that.
PEF was 1/2 to 2/3 of the file size of the DNG that the camera makes, still I would compress them by the computer when uploading since it saves space. When you've 10520 photos on your pc every mb less per photo is a lot in the end.

I really think it's time for a big clean up

The goggle adds is for every one different Vic so can't go to the link you mention.
There is coming a Digital 645 beginning next/ end this year but it's a Japan only product but I'm sure some shops would import it.
