Then better to have used and left than never used at all?

Hey, only cryogenic comments these days.

I hav not used the mode but tried to remember the gist of it from a Ken Rockwell article.

If the D300 uses the same AF engine as the D700/D3 then yup, it's quick.

"what if we had 150MP sesnors, just stick a 50mm lens on and crop into the bottomless resolution" hmm now theres a thought for 2012. No focus issues with a good DOF.

Cheers

I would say that the Pentax DSLR's are no worse than the upper range of othe marks. Indeed, often better. The real AF speeds are on the top Canikon models where the AF engine and "top" lenses perform very well.

All of that costs a lot more money.

Indeed, for my D700 to lock onto faster subjects with gauranteed sucess, it has to be programmed to fire without AF lock and by frame two or three it has locked on and stays locked. So tracking birds in flight will loose the first few frames only. Of course it is in machine gun mode for this.

I have yet to be genuinely let down by Pentax AF.

Is the glass always faster on the other side?

Very slightly Mike. You always know where you will generally shoot and it only needs to be "near" as far as the manual focus. I know it does not work from minimum to infinity but I generally leave the focus on the lens close to infinity and the AF does the rest.

Obviously if subjects are closer then it only needs a slight tweak but nothing that needs thinking about.

I have golf comp coming up soon and will use that combo then and presently have no worries about speed or performance.

I have recently used the 50-135 with the Pentax AF1.7 TC, it is very fast focus due to the screw dive. Downside is the extra cost ofthe AF 1.7 TC!

I agree with Mike-P with regards to the Sigma 70-200, I very rarely leave it at home. It is a true work horse and AF is good and fast.

Hello and welcome.

Just a point, but all my 35mm AF Minolta lenses fit Sony as well as my Maxum 7D which is APS-C. I don't own any cropped Minolta/Sony lenses. In fact if you look at some of the Minolta 35mm lenses and then add the range of Sony cropped glass, it reveals a huge choice of lenses.

I should have said Mac, not Don?
