I currently have a K10D and Tamron 70-300 f/4-5.6 and have been wanting to upgrade to a faster lens for the past couple of years. My primary subject for this has been my daughter's soccer (now a freshman in High School). Up to this point, I have had no desire to upgrade my camera because I'm satisfied with the K10D.
I just noticed that the K3 is at a similar price point as the lens and it makes me wonder... Would I be better served by the higher ISO, improved focusing, and longer reach of the 70-300 if I keep it and purchase the K3? Or stick with the original plan of upgrading to faster zoom?
Hello !
My understanding is you are after more light gathering but that the reach of the 70-300 is ok. So how can you improve on that?
The cheapest:
- Shoot RAW and use lightroom/DxO to develop your high isos images. You get easily 1-2 stop more from a good denoising program and your K10D is old with very basic JPEG denoising software. You may already do that. Beware this is cheap only if you have a decent computer. Otherwise you may want to upgrade/change it and the cost increase quite a bit. While DxO clearly has an edge on denoising through PRIME algorithm you would gain part of stops with lightrooms that require far less memory and CPU to do the job.
The camera
- Buy any camera of the K5 familly (K5, K30, K50, K5-II, K5-IIs) or more recent (K-S1, K-S2, K3) to get again 1-2 stop more from you high iso shoots because the camera sensor is simply better at that. The K3 strong point is FAR better AF that can help on action shootsand increase the number of keepers, but that also a bit more expensive than a good deal on a K30-K50.
The lense:
- Take faster lenses like the 70-200 f/2.8 if you don't need too much reach to gain again 1-2 stops depending of the focal length. The 60-250 would give you less stop gain, but would help on reach if you need it. The price may be off putting.
I would at least consider using Raws and a good raw processing software if you don't do already and changing the camera, that the cheapest thing to do and it would help for all lenses. If you are satisfied with your current autofocus performance and don't tend to reframe you shoots in post processing, a good deal on one the K5 familly member if the most interresting purchase. I'll then consider after a few months of use if I have enough or need the lense too.
