Something little different, but also perfect scene for using smc PENTAX-DA 10-17mm F3.5-4.5 ED [IF] Fisheye zoom

@sophil40. Nice skies. The shot is a bit out of focus, though. The absolutely number one requirement with any astrophoto is to nail focus before releasing the shutter.

I agree Jack. From my experience, the best settings for the astrophoto is everything set to manual. Especially focus. Also, I allways zoom near the infinity, so stars are sharp.

Great action shots! I was curious since I couldn't see your EXIF and picture numbering, what your actual keeper rate was for the day?

I know when I shoot action with the K-5 classic and let myself go a little crazy with the high speed motor drive mode, I might shoot 1000 pics, and only keep about 1/3 to 1/2 of them...

I also noted that different techniques sometimes work better than shoot in burst and pray mode... with my usual luck, if I'm not panning, and listening for the subject to come into the frame and lay on the shutter button, I get the tip of the subject coming into the frame, and the next shot is the tail of the subject leaving the frame.

Where as, if I just go to single shot mode and time it myself, I end up with a much better chance of catching the full subject in-frame.

Alternatively, if I pan with the subject, and prefocus on the spot where they will pass the closest, recompose then start blasting in high speed motor drive as they go by, I will usually get a few keepers. I wish that the K-5 could focus on the fly as I pan in Continuous AF mode, but it just seems to stay on the one spot where you start laying into the shutter button.

I'm VERY curious about your experiences along those lines with the K-3.

Thanks in advance for any reply and help you can give,
Eric

That´s what I tried to do without success. I used the 18 -135 lens for this photo and it's impossible to find infinity point in manual. There is a ring for manual use but there is no stop point ( end or beginning of focus). The next time I will take another lens. I've got a sigma 8 16 and I think that this lens is better for this kind of work.

Infinity is at the end, so you must focus near that point. Do you try focus one star before the final shot?

I shot close to 7000 exposures over the 2 day weekend. My keeper rate is probably around 70 to 75% or better. So far I've been real pleased with my K3 however I was running about the same keeper percentage with my K200D just not near as many shots per weekend. I've been shooting motorsports since 1982. I usually always pan as I'm shooting. With the K200D I would select the focus point I wanted to use. I'm still learning my K3 and it's focus system. So far I'm leaning toward the "Auto 9" setting the placing it in the lower center portion of the screen. Still experimenting though. Here are a few shots from my first weekend with my K3.










and then there is this example of the OUTSTANDING crop ability of the K3 RAW image!

You sure know how to hurt (more like tempt) a guy! Hah! Looks like you are making great use of the K-3's improved IQ !

I should have mentioned, I am shooting much smaller fast moving objects than cars and boats, I was attempting to shoot small model aircraft, so, picture something with a 60" wingspan whizzing around in a big sky at where your autofocus likes to get lost in the big blue, or gray on overcast days. Having extra pixels to crop could help, then I could shoot wider focal lengths and crop later, assuming I can nail the focus.
Thanks for your reply,

The issue is that on this lens there is no end. The ring can turn until you decide to stop. And unfortunately I didn't have the idea to focus on a very bright star. This kind of error will make me better for the next time. And for sure what I will to is to adjust my focus point before dark comes

Astro photography is sometimes complicated, practice and learning is everything. You must prepare, I'm using computer and smartphone software to calculated sunset and moonrise and locating desired stars, in example for shooting Milky Way or StarTrails. But, no matter what, your photo is great!

Use Live View, enlarge x10 and set focus on one star. Remember to have Single shot and SR enabled when doing this or it will be very shaky.

They had a small airshow at the Madison Regatta. I set the auto focus to "Auto27" and that seemed to work well for a small acrobatic bi-plane. "Auto 9" might work better with the smaller RC planes.
