If the filter screw is 49mm, then get a rubber hood from a camera shop.
I have put one on my 35mm F2.4 and is perfect - no vignetting at all. Plus is acts as a protector too. Cost? About £6!

I am one of those very happy owners. Great little light lens with excellent IQ.

And if you are wondering if F2.4 is fast enough, then try this for size.

It is one lens I would consider. My only concern would be the first test. However they may have a K10D that back focusses like mine, hence the out of focus at 100% at 70mm (my Sigma 24-70 does the same on the K10D, albeit intermittantly)

But, its focal range is so useful It would be a combo of both my 16-45 and 24-70. But would lose a stop compared to the sigma. Would that be an issue? Not for travel it would'nt. It will also be an awful lot lighter than the 24-70, so combined with the K-5, will be excellent.

Have you noticed the bayonet end? Yes, it has a seal too. Whether it is fully sealed like DA* is another matter, but it is a good sign.

Here you go.

It will all depend on a number of factors, and what you photograph.

Firstly, what was your previous camera (or should I say current camera)
If, for example you are coming from a 6mp body (*ist series, K100D etc) or a 10MP body (K200D K10D), then the K-7 is a logical upgrade. You will get a better AF, better resulution, better low light performance, and more FPS.

If, however, your current body is the K20D, then the IQ will be the same. the only difference will be more FPS and a smaller magnesium body.

So, unless you are shooting a lot of low light, sports or nature photographs, or you have a K20D, the K-7 will serve you very well.
And anyway, it has the same well designed body as the K-5.

Hope this helps

You got the wrong camera!!!!!!

Seriously though, I have had mine for 3 weeks, and so far. FANTASTIC!

Well, this evening (apart from doing the sound for the play), I took the official dress rehersal shots with the K-5 for the first time.

I had my K20D too as backup this time. Well I say backup, it had my Sigma 24-70mm on it, and the K-5 had my trusted DA* 50-135mm on it.

Results? 450 combined shots later (2-1 ratio on favour of the K-5), the K-5 is simply stunning at Hi-ISO out in the field.

Both were hitting ISO3200 and occasionally more, yet where the K20D was struggling, the K-5 took it all in its stride.
I even had the K-5 set at 1/100 sec and varying the aperture between F2.8 and F8 at one point.
The K20D never went above F4.5 and never more than 1/80sec - more in the region of 1/60.
And still, the K-5 was not just better, but blowing the K20D into the weeds so to speak when it came to Hi-ISO, and the K20D is no mean camera when it comes to ISO up to 2000 for theatre work.

Yes, up to ISO400 there is probably not much in it, but above that, its like comparing a Diesel Astra and an Aston Martin when it comes to performance.
When the play is over I will post some images on my flickr stream so you can see what I mean.

Oh, and yes, the AF is better too, even with a DA* on it, which is not renowned for fast AF speed.

Am I happy with the K-5? errrrrrrr YES!

Enjoy your new purchase Chris. It is a fine camera, excells in the Studio.

I have created a PDF file with all shutters ISO's and apertures based on the sunny 16 rule. It is pretty accurate, even on digital.
So if anyone wants a copy, just e-mail me.

43K! my god, I thought that over 30K with the K20D in just over 2 years and over 30K with the K10D too was a lot!

Do you not work?

Seriously though, Kudos to Smeggy.
