Back to Oak Creek with the 15mm for some fall foliage. Magical place this time of year.

Wow, it's wild how that shock collar is so visible in the dark, and just disappears as it breaks through the atmosphere. :cool:
Neat video, TFS!

Hello,
After putting everything back together (and checking there were no extra parts in the bench) I noticed the lens was out of calibration. The distance ring was not grabbing the focusing barrel in the helicoid.
Took me hours (over several days) to finally calibrate manually to infinity and join both barrels. I used white electrical tape to replace the original vinyl tape that lost the grip. Why white? It was the best one I had available and after careful inspection it really makes no difference as it is nowhere near any light path.
At the last minute, before installing the rubber focusing ring I added a note for future archeologists :)
As if nothing ever happened!
Thanks,

Hello,
A fellow co-worker asked me for help to choose her next camera and we talked for weeks on the subject. Learning that I collect older cameras she told me "I think I have an old camera from my brother's youth". A few days later she brought me this:
An Olympus OM-1 with a Mitakon 28mm f2.8 lens. The OM-1 is from the early 70's. I think it was launched in 1972. It was very highly regarded at its time and it is still popular among film users.
This particular one is a later Motor Drive or MD model launched in 1974 according to my quick internet search. It has provisions to attach an external motor drive thru the bottom plate.
So this will be a follow along as I'll try to revive it. I am by no means an expert. Just a Pentax biased enthusiast with a bad habit of taking things apart. :)
So this is how it got here:
The self timer lever fell off while tinkering with it. The shutter doesn't always complete the cycle. The lens is dirty and the aperture blades are not working properly. It will have to be taken apart for servicing, but that will be another time. Found and downloaded a service manual online.
It has definitely seen better days.
So here we go. I'm studying how the shutter release and advancing work and I think it is just a matter of lubrication. A very small drop of light machine oil and it seems it started to improve.
Stay tuned as this will be a fun one.
Thanks,
|

Hello,
Ehhh... ahhhh.... hmmmmmm.........
Going beyond where I've ever gone before :)
The lens was not working. Noticed the blades were barely moving. Started to take the lens apart to carefully clean the blades as I've done before but suddenly, BOOM! One blade fell off..... So, what can possibly go wrong? It was not working anyways...
Yikes! :)
Thanks,

I just received an Irix 30mm f1.4 lens for my Pentax K-1 and did some test shots of the Milky Way.
A short summary:
- wide open the lens shows some flares / coma on brighter stars
- at f2.8 the lens is very sharp, comparable to the Pentax 24-70mm at 35mm f2.8, but without any of the chromatic abberations of the Pentax lens
Irix lens at f2.8 right, Pentax 24-70mm at 35mm f2.8 left:

Very pleased with my 15mm last week up among the high alpine lakes of the San Juan mountains in SW Colorado. Wildflowers are out and the colors everywhere were spectacular. These are both taken with the K1-II + 15mm Blackstone w/ EDGE polarizer attached. I usually find the polarizer tricky to use with this lens for a lot of my landscape shots because of the varying impact on a sunny blue sky across the frame, but I managed to avoid that issue here and get the polarizing benefits I was hoping for.

Here's a few of this morning with the 30mm F1.4
and one more which I tried to optimise sharpness rather than shallow DOF in order to get front to back detail sharpness so I could apply a photo illustration effect

Dahlias with K-1 and Pentax 67 135mm f 4.0 macro, well, more of a close-focus lens than a macro, but great for flowers.
