New K100D Super
K10 Super new features, probably not too much for current K10 owners to get excited about, development funds should go to the brand new model. My guess is that there will be a few tweaks with firmware, maybe better flash support and of course the auto pict modes. If I am right the pricing will b...

New K100D Super
http://www.dpreview.com/news/0706/07062801pentaxk100dsuper.asp First pic I've seen of it and the styling is very K10D. It looks the same as the K100D, in fact it is the same identical chassis so the K10D looks like it not the other way round as the K100D body was around first. Yes, this ...

is the 18-55 a MACRO lens?
Hi all. I have a couple of old film cameras (ME and MX) with an array of lenses from 20mm to 500mm. I've been waiting to move to digital hoping a 24x36mm CCD sensor was about to be offered, but I lost hope. I am now considering a K100D and my question is: the standard lens has a MACRO capability?...

Reasonably close, but you can get practically the same image with the 50-200 set at 200 at 1.1m (and better image quality in my opinion). All your old glass should be usable on the K100D and K10D so I don't think you have to worry much about getting new lenses (unless you want AF, which I must sa...

K10D noise reduction at slow speeds
AFAIK, the in-camera noise reduction just does dark frame subtraction which takes a second "shot" with the shutter closed and subtracts the noise from the original image. This helps to lower the noise and hot pixels, but as George rightly says you can do a much better job on the PC. The...

TAMRON 28-105mm F4-5.6 IF PAF Fit on K100D ????
Guys , how does this lens rate on a Pentax K100D or similar Does the focal length when on the K100D equate to 28 - 105mm or does the magnification alter .....might be a stupid question but just found one on the internet for £119. Anyone using one The focal length is fixed. What changes is the...

Tokina 500mm mirror lens + use with DL2
. Don't forget the 35mm-equivalent focal length is 750mm, so you will need at least 1/750 sec to avoid camera shake. Probably faster... Not really, just because it is a cropped sensor doesn't mean it will act as a longer focal length in shaking respects. The shake would be just the same on a FF came...

For the same size of final image, you have to enlarge the digital image one and a half times more than the film image. That increases the camera shake by the same amount. I thought I'd understood all this :( Is it not the case that if you take a picture with the same lens of the same thing at ...

Chris, this is what you are missing: Shake is always present. Every shot you've ever taken has camera shake to some degree. The 1/focal length "rule" is just a guide to tell you when it is likely to become visible in a large proportion of frames printed at normal sizes. With a crop s...

And for your supplementary question Chris, the answer is yes, exactly the same distance. Going back to your first question, you're right in that an object will be the same 'size' on film or digital, but imagine that you took a photo of a tennis ball, using a film body and a K10D, using the same l...

It really is very simple. The smaller the recording medium (film or sensor), the more you have to enlarge the image, and when you enlarge the image you enlarge the blur. :D I hate it when people say "it really is very simple", since even if you're less paranoid than I am, it's not hard ...

A picture taken on 35mm film with a 75mm lens will be equivalent to a picture taken on digital with a 50mm lens. But the final 10x8 print from the digicam will have to be enlarged more than the 35mm image. And the enlarging will accentuate the shake. George, I understand this perfectly, but with...

The reciprocal shutter speed rule is meant for obtaining a sharp-enough image full frame - hand-held. It's only a rule of thumb. If you have a steady enough tripod you could shoot at 30 seconds and still get an image free of shake-induced blur (but you'd probably have image movement though!) ...

When you print the two pictures, provided you don't crop, the squirrel will be considerably smaller in the 35mm print. It will appear to be sharper. Agreed. I've never disputed this, in any of the ways you've expressed it. If I've appeared to, then I'm sorry. The squirrel may be the same s...
