i ve pentax equipments;35mm macro tamron 28-75 55-300 and k-x with k200d and i will probably replace my tammy with 70 limited
i want to upgrade my k-x to k-5 or d7000 with new lenses (85 1..8 35 1.8)
actually i love pentax and its limited lenses
they are small and optically really nice
but pentax loses its price advantage .70mm limited and 35mm limited are more expensive than nikon's 85 35 combo (1200 $ against 625 $ )
I cant say anything about the D7000 since Ive never used one. But I own a D300 and a K5 so its easy for
me to compare the two. The D300s focussing is not just better its in a totaly different leauge. In all fairness though the D300 prob has the best autofucus of any camera. I noticed a slight improvement on the K5 after downloading the latest software. I hear talk of poor low light performance in the K5 where as I personly dont think its that bad. Its not anywhere near as good as a D300 but not that bad though. Not all pics are spot on 100% of the time with the D300 even, but they are always 100% close enough to be usable.
The problem with the K5 is that it acheives focus lock Ok.
So you expect to have the pic in the bag.
Only to find some of the pics are that far out they are simply unusable. Ive noticed it works fine when close up,
say upto three quater body lengh but loses the plot when you go further back. Its not that the camera doesnt lock, because it finds lock ok. Its just not accurate. In a lot of circumstances it wont matter so much IE... shooting close objects or landscape where DOF is covering the sharpness etc. Flash accuracy is also poor. Its poss, this could be related to the focussing being out though, since the camera also uses this info.
Not sure about that.... but I think thats what it is because again, at close quaters its spot on.
Other issues ive had with the K5 are stupid irrating little things like I press the reveiw button and no pic comes up. Turn the thing off and on and its fine again.
There is a lot to like about the K5 for sure, and when it
gets things right its poss the best APSC camera on the market. Again, in all fairness, the K5 is half the price of the D300 and as such considering its capabilitys its a total bargain.
