I know this is kind of a clique type shot, but it is a little different from what is usually posted on here, so I just wanted any constructive criticism and to see what I could do to improve it.

What is your experience with a K-1 and DA* 300mm F4?

Hello,

I'm new here, and this is my first post. I really like this forum.

I've just started using a K-1 with a DA* 300mm F4. I've set the in-camera lens AF Fine Adjustment (Wrench Menu item 25) and further AFC/spot but I find myself using the manual focus more than the autofocus, especially on moving subjects.

Reasons:
- I find the autofocus is very good on static subjects, but is searching a lot when subjects are moving.
- I sometimes find the level of accuracy of the autofocus not accurate enough, in relation to the level of detail that can be achieved with this camera. In spot mode, I sometimes think the spot is too big(?).....

I've included two samples of a hand held manual shots.

For K-1 / DA300mm users: What is your experience with this combo? Did you manage to find a setting that improves the autofocus, both in accuracy and (tracking) speed?

Thanks!

Don't let us talk about paperware.

Hang the difference of the camera weights of ~360g around your neck and walk around with it for only one hour. Do you feel it? What about after two hours, three, ...?

Take both cameras with same lens, maybe the DFA28-105, in your hands (~ 1.1 kg and 1.460 kg). You don't feel significant difference - neither in weight nor in size? Interesting.

About Lens Hoods IMPORTANT!

I have often said that i hate my FA50mm F1.4, sure its a sharp lens at F4.0, some say even at F2.8 but when i want the speed the sharpness
just isn't there, in fact the only fast lens i have that doesn't really suffer a lot from low sharpness wide open is my FA35mm F2.0...

In the case of the FA50, its all about low contrast, same goes for the F50 F1.7 and Sigma 24mm F1.8... and a little bit on the FA77mm F1.8 Ltd...
I know a hood is important for getting rid of stray unwanted light, but you really never no how important it is until you have a bad case of low
contrast for a given lens and you try a lens hood on it. in a personal review of the Sigma 24mm F1.8 someone wrote online they made a really
interesting point, The film (FF) lenses come with a hood that blocks stray light for the FOV related to full frame, however on a crop sensor the
hood needs to be 1.5 times longer to get the greatest benefit, he said he used his Sigma 70-200 F2.8 hood on his 24mm F1.8 without vignetting
and with far better contrast... the other thing we all should understand is that zoom lenses hoods are only good for the widest FOV...

with this in mind i picked up a lens hood off ebay said to be good for 37-90mm ore something like that, its a 49mm thread and its about 37mm
long and 60mm in diameter (it came with a 58mm lens hood)... the hood is longer then the built in hood of the 77Ltd too by about 1.3 times.

here are some of my conclusive test to confirm how much a lens hood helps

Testing back light glare 50mm F1.4 @ F1.4, F2.0, F2.8
what the test looked like


100% crops description written on photo







You can clearly see a marked improvement in contrast and overall sharpness

Now here is one test for the 77mm F1.8 at F1.8, no hood, built in hood, new hood

what the test looked like


100% crops


Look at the contrast in the text and the effect of purple ringing on the black dots

I hope this is clear for everyone now that the right lens hood is rather quite important to improve lens performance especially on fast
primes... now the next thing i have to look for is a larger hood to fit my 24mm F1.8

The old term was "Coke Bottle" glass. Now, that's not as much a reference for people.

The FA50mm is a good lens, it will be a good lens on any K-mount camera.

Have fun researching!
