M* 300mm f/4 = My Favorite Lens...

...for this week at least
I just love the way it looks, feels and renders.

The downside is using my K-5 with this lens though (not this lens specifically, but manual lenses in general). It is difficult to shoot action using manual focus with this camera because the VF is mediocre at best and there is lag when using Live View.
Even when I got focus confirmation (hexagon and beep), focus was still off.

But when I nailed focus, it is a sharp one!
Here are some snaps I made at rainy, muddy Santa Anita Racetrack last week.

Thank you guys...
The interesting part is that I got waaaaay more keepers with the M* manual focusing than I did with my new DA*50-135mm autofocusing. The DA* was back focusing like crazy. I have to adjust my focus with that guy.

Chances are almost zero that you actual backfocus issues that would be visible in a picture of a horse - BF issues are measured in millimeters, not meters. Most likely, the camera just had trouble focusing on the moving horses and simlly chose to focus on the background.

Your hit rate should be double if not better using any MF lens (with CIF) against a DA* lens in AF when shooting moving action and more so if shooting race horses - I find shooting the 50~135 in MF with CIF enabled I can get a near perfect "in focus" hit rate as opposed to maybe a 10% in focus hit rate with AF. Sorry to note this again but SDM is near worthless shooting any kind of moving action sports, HSM seems to be blazing fast and spot on.

Love the pictures - #4 is awesome!

I don't see how this is possible. Doesn't CIF require an MF lens to be mounted with the focus setting set to AF-S?

Yes, CIF requires a MF lens to be mounted with the focus setting set to AF-S.

When using a DA* Lens or an HSM lens, when turning the "Lens Switch" to MF it tells the body that a MF lens is attached thus enabling the use of CIF...

Thanks for the heads-up Marc. That does make sense.
I will do some semi-controlled tests to see what I actually have.

It is a very nice lens, I have the brother lens A*300/4 and I am keeping it for sure.

Its so stupid that these didn't have tripod mounts on them, the A* too. Have you tried using one of the canon knockoff tripod mounts to see if they fit?

If you lend me the $450, I will be sure to get it
Sarcasm aside, it would've been nice at the racetrack to have AF, but it wouldve been too much reach for that situation. But i am definitely intersted in that piece....down the road

Also, I want to wait to see if the new TC actually sees the light of day.

with the AF 1.7x TC, you can do close focus up to about 1.5m~2m
