Comment by dcweather posted on Pentax K50 plus Pentax DA 55-300mm f4-5.8 ED WR lens. at 13/10/2014 - 11:13
look on dpreview after looking at the k50 i would go for the k5 or the varients of it as you can do a lot more with the k5 than the k50 and there should be a photo of a falcon on there and a top fuel dragster which i have taken in full flight so to speak

I think with a car you know where it is coming from and going to and it is big. If the falcon is close or is semi-captive again it is predictable to an extent. The biggest problem I get - and it happened today in good light is a Kestrel appears in the sky, a fair way distant, you point the camera at it and press autofocus (Continuous, but same in other modes) and you just get a hunt through blue sky, you then have to look again to see where it has gone, now out of frame and try again - if you get lucky and it finds it you can usually track it.

I'm not giving up and there is a slight possibility that my DA* 300 doesn't have as snappy focusing as it should, although the Kingfisher pic in my gallery shows it is capable at times.

" As you can see, there wasn't a long wait for the K-3."
... and we always bite as this poster did!
"Sorry - was that humour? True I see no people, but I don't think anyone climbing the waterfall would get to stay long - assuming you are serious. And if you're being funny it's rather sad. Why does Pentax continue to get a disproportionate number of dismissive throwaway lines from DPR staff?"
Nevertheless they did apparently completely fail to report on the Pro stand which had the 645z as well as other high end lenses and was apparently quite a crowded stand.

It's all to do with the focal length changing as it's focused
closer. IF lenses focus by changing the focal length.
This article should cover it.....

Hi all,
Pricing is an issue which I am addressing. There are reasons which I cannot go into why some pricing is different on Ebay, but once our next project, our stock live till system, goes live, this will be sorted out and pricing parity will be the norm!
Nooo! I don't want parity unless it's downward! I love my Q body at your Ebay giveaway price

Nearly all the lenses released
Most 400mm lenses are only 400mm at infinity.

I'm being a bit lazy but could you remind me of the theory behind this. Does this also imply that say a 300mm will give more than 3/4 the magnification that a 400mm would at the minimum focus distance?
