I am looking for a lens for my ist DL that can be used for indoor speed photos. Specifically, for taking pictures of dogs doing flyball. As the name suggests, the dogs are FLYING (over jumps) with a tennis ball in their mouth. I cannot use a flash as that could cause the dogs to stagger into the jumps instead of jumping them.
I found a Pentax SMCP-FA 50mm f/1.4 Lens on Craig's List for $250. Is this a good price for this used lens and more importantly, will it allow me to take low light, speed photos? Right now I am trying to take photos with a 2.8 telephoto lens. Not only are the pictures somewhat blurry, but many times, I cannot take a photo at all without delay in shutter depression or it won't snap the photo at all.
Many thanks for advice or opinions!
So the problem with the 50 f/1.4 is that the DOF is SO narrow close to wide open that you'll never get very sharp photos, not to mention it doesn't have much reach. So you'll be shooting at f/2 or f/2.8 anyway to get back some of that DOF.
I shoot a lot of dog agility and the indoor places are really tough. To get anywhere near the shutter speed you need to freeze the dogs you need to use the highest ISO you can possible use (ISO 3200 hopefully) and an f/2.8 (or faster f/2) lens. This will get you shutter speeds around the 1/320th - 1/500th mark and with excellent technique can freeze the action. The catch is at 1/320 you want to limit the movement coming right towards you, instead you want to be in a position where you'll be panning a little bit.. that will compensate for the slow shutter speed and the dogs movement (if that makes sense)
Don't worry about the noise at high ISO, you can always PP some of it out and noise is preferable to blurry dogs
For newer AF lenses really the Sigma 70-200HSM is the lens you'd want (of course you'd need a new body to take advantage of it).
Here are some sample shots of what you should be able to get indoors:
One thing to mention is that this is going to take practice. This 1st one was my 1st time trying to take indoor agility shots with my K20 and DA*300 and it isn't all that great (I also just processed this quickly for this thread so it isn't the best PP job). I did run noise reduction on it and it is about a 50% crop from the original.
1/320s f/2.8 at 128.0mm iso3200
The rest of these were taken with a different brand kit but techniques hold true for any kit. These were all after a lot of practice and learning what works and doesn't work for me.
