Thank you, Chat.

In this focal range, the Samyang 135 works well with CIF, and is both cheap and very sharp...

Great. I will definitely look at that. Thank you.

I shoot sports quite often with manual lenses. Mostly windsurfing, riding and skiing/snowboarding. Depending on the scene and lens I use pre focus, focus set to infinity or catch in focus:

- Pre focus is good if you know exactly where the best action will be. Then you can make sure you have spot on focus. With K1 crop mode might be good idea to have faster burst.

- When you shoot action landscape it's often practical to pick a lens with short infinity focus distance. Then shooting is really easy. Just keep camera shooting. (My son took this one. I just set camera ready and gave it to him and told him to keep it rolling while I ski by

)

- Catch in focus is good when you need to follow the target and try to find the right moments to shoot. Good light is needed for CIF to work realiably. I typically frame wider than I need to be able to crop to compose as only center focus point is used for CIF and therefore you need to keep target in frame.

Of course if you get modern lens with fast focus. K1 should be good enough to catch the action with AF, which is a lot easier.

These shots a great. Thank you.

For sports, I use fast primes and the focal length depends upon the sport and from where I shoot. My two most used MF lenses (for sport) are the Voigtlander Nokton 58mm f1.4 and the Zeiss 85mm f1.4. I use also the Pentax A50mm f1.2, but I prefer the VL58mm in terms of IQ.

Hope that it may help.

I am considering the Irix 150mm with it's wonderful hyperlocal scale.

The largest aperture of the Iris 150mm is f2.8. IMHO, this is not fast enough for many fast indoor sport and low-light fast sport activities, unless you boost the ISO to very high values.

My 5 cents.

Oh, it's outdoors. Light won't be an issue. There have been some nice 70-200s on the market place lately. I may go that route. Thank you.
