Excellent! There's a kestrel that haunts the apartment building across from my home, and I've attempted to take many a photo as good as yours. Though I haven't quite gotten there yet. Thanks for sharing!

New Acquisitions: Pentax S1a & Pentax ME!

Well, I've been able to get conclusive confirmation about the levels of radioactivity associated with my Super Takumar 55mm f/2. I contacted a Radiation Safety Officer at a local university, and much to my surprise, he agreed to undertake a few tests on my camera equipment. It turned out that my 55mm f/2 was not emitting any measurable radiation.

On the other hand, a 55mm f/1.8 that I recently acquired was measured to emit approximately 2 microSieverts per hour (gamma and beta radiation). This radiation was coming from the lens's rear element. I was told that the typical yearly radiation exposure associated with living where I live is approximately 2 milliSieverts per year, and that an exposure dose of approximately 10 milliSieverts per year is deemed to not be too awfully dangerous for members of the general public.

The measurable radiation declined substantially (to approximately 0.5 microSieverts per hour) when measurements were taken at the back of my Pentax S1a when the 'hot' lens was mounted to the camera. Additionally, a measurement of the unmounted rear element of the lens at a range of 10cm showed a similar dose of approximately 0.5 microSieverts. Increasing the measurement distance to 1m showed no discernible difference as compared to the background radiation being detected in the office where we were standing.


In sum, the Radiation Safety Officer with whom I spoke explained that I would need to hold the rear element directly against my body for about 1,000 hours in order to achieve a level of exposure equivalent to what everyone experiences in the area where I live on a yearly basis. This works out to about 2 hours and 45 minutes every day for 1 year. If mounted on a camera, it would take approximately 4 times as long (i.e. 4,000 hours / almost 11 hours per day for a year) to reach the typical level of exposure in my lived environment.

All of this information has helped me to feel more comfortable keeping (and using) my radioactive lens.

I hope that this information proves of interest to others!

What an interesting thread filled with lots of interesting comments!

I experimented with my mom's old Pentax K1000 about 15 years ago but then began my digital camera journey in 2011 with an Olympus E-PM1 and have stayed with the Micro Four Thirds system (currently using a Panasonic G80 / G85) since then due to its ease of adapting vintage glass from all the major camera brands. With Olympus seemingly on the path to moving out of this market space, I've drifted to the Pentax system in part because I own a smattering of cheap, manual-focus film lenses already. I recently got a good deal on a lightly-used Pentax K-5 accompanied by a Sigma 17-70mm Contemporary lens.

If I'm being completely honest, the level of interaction and good-natured cameraderie on this forum has played a significant role in my decision to move towards Pentax. I am not in a financial position to "upgrade" to a different Pentax body anytime soon (maybe in 3-5 years :O), but I'm looking forward to trying to make the most of the K-5 with a view to sticking with Pentax moving forward!

Welcome to the forums from the Fenlands of England!

I recently bought a secondhand K-5, and I'd wager that that model is a great value for the amount of photographic potentials it provides at (what is now) a very manageable cost.

Amazing that they're a family of albinos! Hard to believe that they've been able to survive, but maybe they can blend in with the stones.

Hopefully promotions like this will become more common worldwide!

Might this be an indicator that profit margins for the K-3 III are doing better than all the hyper-mirrorless anti-DSLR fanboys thought?

Welcome to the forums from the Fenlands of England!

As another user working primarily in a different system (Micro 4/3), I would offer a word of caution: it's very easy to get sucked into purchasing vintage (and modern) Pentax gear the longer you remain active in this forum. Post and read at your own risk!!

Poll: Should I Buy a K-5 This Week???

Imagine my surprise when I logged in this morning to find that forum members were waiting on the 'next installment' of this saga :cool:

In fact, I did end up purchasing a secondhand K-5 bundle with 5,000 shutters shuttered from the electronic-bay. The total cost was $375 USD for the body, a Sigma 17-70 F2.8-4, a Manfrotto Tripod, a carry case, and various original K-5 accessories. This was a slightly more expensive deal that the original one from my neighbor, but I was thinking that $275 USD is the going rate for the 17-70 lens and that $100 USD for the K-5 body is a relatively good price.

Thanks again to everyone who provided their opinions in the first place—the camera-derie and helpfulness of this forum has played a large part in my interest in Pentax gear! :lol:

Pentax S3 - worth fixing?

I've got some similar problems with an S1a that I recently acquired. I haven't started my repair efforts, but there are a few places online to find service manuals:

Product Details | Pentax SV Service Manual | Pentax | Service Manuals | Learn Camera Repair

PENTAX MANUALS

I would love to hear / see which areas you lubricate, what oil you use and what the outcome is! I'm hoping to post photographic and textual evidence of my own efforts eventually, too!
