The hype and enthusiasm for the supposedly lightweight K7 seems to me to be misplaced. The following figures are all from Pentax UK's website:
So the difference is 45g. That means that the K7 body is a staggering ... umm ... well ... 6.29% lighter than the K20D body. Not so staggering, is it?
But nobody uses a body on its own (unless they are using their camera as a cosh). Add on 220g for the std 18-55 II kit lens, 80g for the battery and SD card, and we're looking at a weight-saving of 45g off a K20D's 970g. That's 4.64% lighter.
Even using the lightest lens I can see (the
smc DA 40 mm / 2,8 Limited at 90g), we're looking at the following minimum working weights:
- K20D (715g) + battery&SDcard (80g) + lens (90g) = 885g
- K7 (670g) + battery&SDcard (80g) + lens (90g) = 840g
So the lightest K7 combo is only 5.32% lighter than the lightest K20D combo.
But if we're using the
smc DA 60-250 f/4.0 ED (1040g), the overall reduction in weight is only 2.45%.
I'm glad that the K7 isn't any heavier than my very heavy K20D, and any weight-saving is a step in the right direction. But the difference is so small that it will probably be completely un-noticed in use.
I really like my K20D, and I'm sure I'd like a K7 even more. But the hype is silly.
