Comment by Horst posted on Lens hood and polarizing filters at 09/04/2014 - 13:42
I went for a 4 day holiday last week, and decided, because I saw some pictures on this forum using polarizing filters to improve the blue of the sky's, to invest in a few polarizing filters to take with me.
We still had daylight savings time and the light was good.
The lenses I took with me where: the FA36mm f2,my F 35-70mm , the DA WR 18-55mm, the Tamron SP 24-135mm the Sigma 70-200mm and just in case I wanted to make a picture of my wife, my FA70mm f1.8.
I had the right size polarizing filters for all of this lenses.
However, the only 2 useful lenses where the F35-70 and the FA70mm
Why? Well the damn snap on lens hoods on the other lenses did make it very hard and tedious to adjust the filters. This included the Pentax hoods with the little cutout. it really didn't help much.
The lens hoods on the 35-70 and 70mm lenses where round screw in types and I was able to turn the lens hoods to adjust the filters. Much easier.
So what I have done now, is to order screw in hoods for all the other lenses to. Next time i won't have this problem.
it shows you, at least this is what i think. The manufacturer and designers of this type of equipment, don't actually use it in practice,
or else the would not design useless lens hoods like this.

I think both Smeggy and Alien are right. However coming from a Marketing/PR background, Pentax have missed a trick. To the great unwashed, a ‘Pro’ Brand creates an aspirational feel. Over many years Nikon/Olympus/Canon have played this card. In their product portfolio they have ‘top end’ kit, but then produced cheaper stuff, that the punter can buy into and thus imagine they are buying into a ‘Pro’ experience. Pentax used to promote itself as ‘Pro’ in the 60’s, but have, in recent history, seemed to be more apologetic about their offering. I do see this changing with Ricoh. But more needs to be done.
If they pick this up I want a FEE

I remember, when I bought my Spotmatic in 1970,the competition Minolta, I think it was the SRT 101, had a 3rd photosensitive device in or near the viewfinder, to compensate for stray light in to the viewfinder..
I wonder why it is not used in the current cameras.
Some cameras also had a sliding cover for closing the viewfinder window when using a tripod and cable release. This should be easy enaugh to do now, instead of this idiotic slid on cover, which gets lost after or just before the first use.

Comment by Horst posted on K-5 exposure: difference between LV & Viewfinder at 09/04/2014 - 11:58
The other day, I was looking on a newly made lot of my K5 pictures on my computer screen.
Looking closely I noticed some spots. They where always on the same physical condition .
On each picture i had some near the bottom and one on the left hand side.
I bought one of this sticky cleaning gadgets. ( not cheap).
When it arrived I set up the camera in its sensor cleaning position and started to use the cleaning stick according to the instruction.
After the cleaning process, I made a picture of a white sheet of paper and totally over exposed it. I downloaded it and bloody hell, the spots where still on the same position. nothing had changed. I repeated the process 3 more times: N0 good.
Discouraged and upset that I have to send the camera in for cleaning, I stopped the picture view. and looked at something else on the screen.
What did I see: The bloody spots where still visible.
The spots where dirt on the screen. I cleaned it , felt like an idiot and was relieved.
Next time I know, what to do first.

I remember many of my old Leica lenses had the real focal length scratched on the back or when the lens head was taken of the 90 and 135mm Elmars with pencil written on the inside of the focusing mount.
For example with the 90mm lenses, I had anything from 87- 92 and with the 135mm lenses from 130 - 134.
it didn't make any difference when photographing, but it was important when fitting the focusing mount.
The better fixed lens cameras had shims fitted when the cameras where manufactured to compensate for the slight variations in focal length of the objectives
