Comment by Horst posted on Shake reduction problem. at 31/08/2013 - 08:01
Hi, I hope anyone can help me.
I have a K5. The shake reduction is switched off.
I try to switch it on again, but the shake reduction line is grayed out.
Can you help me?
The lens I use is an Pentax auto focus lens.
Regards, Horst

Try using a ND Filter of 2 -3. Then you can keep the small dof. and use the AV setting.

I bought a Katzeye screen about a month ago. It was OK, but the actual prism ring is somewhat annoying. So I took it out again and put my existing screen (K5) back again.
If I could get a screen without the prism ring, but with only the split part, I would buy this. As it was, it seemed a bit of a waste of money.

Not long ago, Hard disks had 500GByte of storage. Now its over 2TByteJohn Schick wrote:

at no extra cost.
Did you upgrade from your Olympus E-1? And if so, why?

Why would you need larger lenses, than for APS-C DSLR?John Schick wrote:

There are plenty of F and FA lenses which cover 35mm fully. Why should new lenses be so much more expensive? Don't forget there is such a thing as competition.

The focal length does stay the same. For example a 300mm lens is always a 300mm lens.
The Rabbit or whatever wildlife you photograph is the same size. You just get some extra on the image. Maybe a second rabbit.
If you crop it back to APS-C size your rabbit is exactly the same size as with an APC-S sensor. Without any loss in quality.

I tend to agree with Smeggipants. As soon as any manufacturer releases a reasonable priced FF SLR , All the others have to follow.Smeggypants wrote:

This does not only apply to professionals or semis, This applies to anyone who is a fan of SLR's. Professionals or Amateurs alike. The Advertising from the companies which have them ensure, that APS-C will be forgotten and it will all be FF. At least in the SLR market.
If this happens, and I believe it will be in the near future, and if Pentax does not follow, it will be the end of Pentax SLR's. That is if it is still in existence by then.
Why is this my belief? Simple logic. Looking back to see the advances in silicon over the last few years,it is easy to see, that a FF sensor , cost-wise and quality wise will not be long in coming.
APS=C and other smaller sensors where only used , because it was about the best that could be done at a reasonable cost. This will change.
The more Cameras with FF are made, the cheaper will the sensors become.
Size will not be a problem. Naturally, the FF sensor is larger than an APS-C. Big deal. There are much less mechanical components in a digital camera . Also there will be more efficient batteries which can for a smaller size deliver as much power then the existing ones.

If sensor quality improves, it will improve with all sizes.Then you'r back to the beginning. A larger sensor will always be more universal and better.gwing wrote:

Hi, I have 3 lenses here
.
1 SMC Pentax-A 80-200mm f4.7-5.6 and
1 Pentax-F Zoom 70-200mm f4-5.6 and
1 Sigma Zoom 70mm-210mm f4-5.6 UC II
I compared the 3 lenses for sharpness and found the Pentax-A to be the sharpest.
The other 2 are less sharp and both are about the same.
The settings where all the same.
200mm f5.6 Flash with 1/180sec.
The Pentax-A lens is of course manual focusing only. and the lightest of the 3 lenses.
The Pentax zoom 70-200mm is the heaviest and a real monster.
Did any of you have any experience with any of the above lenses?
Regards, Horst

Thats why I think Pentax if they do bring out a FF camera they will play it very safe indeed, no new mount, use the same Sony sensor as in the Nikon and Sony Dslrs and keep the price a bit lower then the compitition.

Yes, the crop factor is 1.5x, but that's the linear dimensions, not area. FF (36x24mm) is 2.25x the size of APS-C (24x16mm), so you actually need the D800's 36Mp sensor in order to get the same pixel density as the 16Mp sensor in the K-5. A 24Mp FF sensor would give a 10.6Mp image if cropped to APS-C size.
Hi Dan. You are perfectly correct. I mucked that up. It should be about 36k.Dan wrote:

I have mentioned in one of my earlier post, when i worked it out like you did and arrived at your figure.
Thanks for your comment.
It also looks like you are the only one who read my comment and took it in.

I had the self timer set to 2 seconds. If the self timer is set, it seems to turn the shake reduction off.
maybe this helps someone else with the same problem.
