I regularly use my K3 with the 50-135/2.8 to photograph basketball indoors. I find basketball is the biggest test of my skills and the camera/lens abilities as it is fast action in generally poor light and so any technical improvements in camera and lens technology is very welcome. Particularly improvements in low light IQ (better sensors for lower noise) and AF speed.
I am looking to upgrade over the next 12 mths or so and plan to head towards full frame with 70-200 F2.8 and fast AF and fast FPS. I figured that if FF was the ultimate goal and some FF lenses required then perhaps changing to Canikon was an option to access better sports AF and fewer missed shots? However, the $ to changeover cant be justified especially when it doesn't bring much improvement to the rest of my photography (wildlife, family, bit of landscape). So my first step will be to get the DFA 70-200 and then the K1 (or possibly K3iii or K1ii depending on timing)
I am looking for forum members who have first-hand experience with the improvement in AF-C between K3 & DA 50-135* and the K3 & DFA 70-200* specifically for sport and indoor sport like basketball. How much better is the AF-C on the K3 & 70-200 than the K3 & 50-135 for basketball?
Further query is then how much improvement in AF-C & IQ is being seen when moving from the K3 & 70-200 to the K1 & 70-200 for basketball?
I'd really appreciate hearing the experience of any Pentaxians who have gone down this route. Thx in advance.
