Originally posted by Amanda I currently have a K100DS which I have had a great time with.
For the last couple of months I have been considering upgrading to a K200 or the K20.
My reasons are I crop a lot and more MP would help with less noise. I am out and about a lot so a sealed camera would be a god send.
NOW, I am thinking....what about a decent lens to go with what I have. Learn and play with that before getting a new body.
I am finding my 18-55mm (F3.5-5.6AL) can't handle low light and I am in the woods a lot with the children right now and not getting what I want no matter how many ways I shoot.
I also have a Sigma 28-300mm f/3.5-6.3 for SA and Pentax 35-105mm F-4-F5.6.
So nothing thats good for low light.
I also want sharper images which I have been told will involve a better lens.
My question is tho, which one! There are so many. I know I need a low F number but thats it. Its all a bit mind boggling so I'd appreciate advice on this.
So to conclude, do I get a new body or a new lense
Amanda, your problem sounds, as whether the unsharpness of your images is mostly produced by long shutter speeds. This increases camera shake (= blurred images) and ofcourse the kids are moving all the time, too (= blurred subjects). I think, lens quality comes a long way behind that basic problem.
You have basically three options to counter camera shake and subject movement:
- higher ISO setting
- using flash
- using a faster lens
For moving kids in the woods, I don't think, a fast prime lens (like the 50/1.4) would be my preferred choice. I use a 18-50/2.8 for that and pump up the ISO to 400 or 800. I often use a flash too (but using a longer shutter speed, to allow available light fill the background).
If you often need to crop, you are simply to far away from the action. It is very impractical to use a longer (tele) lens, even a zoom, if you are out with the kids, because you will often find yourself too close to the action, then. My suggestion would be, to participate in the action with your camera. Move with the kids. That not only remedies the need for cropping, you will make much better photographs as well.
The situation is a bit different for a hiered photog, because he can stay at a more convenient distance, but I assume, you are in the wood, to accompany the children (family?).
A Pentax K20D will help you a bit, as its high ISO performance is very good, indeed. You can use it up to ISOI 1600 easily, but even at ISO 3200, the images are very printable at standard sizes. But you can at least try to improve your technique with your old camera before spending loads of money. If you get sharp images with your K100, with higher ISO and accordingly higher shutter speeds, ten you may think about a better camera. But the K20D will not lead automatically to sharper images.
