What's the highest rated lens you own according to PF?

The highest rated lens I own is the F* 300mm, F4.5 lens which has an overall rating of 9.89 (39 reviews). Yes, I do think it measures up.
The FA 31mm Limited (9.51)(83 reviews) and FA 77mm Limited (9.73)(94 reviews) also hold up to their ratings. I really think the 77mm should be rated higher than the 300mm, but that's just opinion.

All of these came to me used, but in great shape, so, yes, I was happy with the purchase price.

I think you'll find the Pentax DFA 100 macro to be a wonderful addition. I'm certainly very happy with mine.

If your camera store has or can order it, maybe apply the credit there?

K1 is giving Nikon D850 a heavy beating
Posted By yucatanPentax

I'm curious if other owners of the K1-II have seen this purple shadows effect with HDR as described in the video? At low ISO's, it seems the saturation and WB of the Mark II give a more pleasing photo. But in low-light shooting, it seems -- just from this video -- that the Original K-1 has an advantage.

Any owners with both, or having used both, care to comment?

How do you protect yours?

I hate to start the filter debates, but (you know when they say that.... ;) ) in my experience, a filter is likely to supply broken glass which may damage the front element when dropped. And a sturdy lens shade is likely to crumple when dropped, absorbing some impact. So, I am not of the protective filter school. I have found the problems with reflections and other anomalies to be more trouble that it is worth.

Use lens caps on both ends (when removed from camera). Use lens hoods while shooting. Keep the camera is a dry place. Leave a lens on the camera. Only exception might be a long, heavy lens. I'd keep smaller ones on it, but always remove a premium or heavy lens. They might be prone to put pressure on the lens mount depending on how the camera is sitting while not in use. If no lens, use a body cap on the camera. Wherever it is stored should be as dust-free as you can manage. A cabinet, etc.

Change lenses with the camera body opening pointing down so that any dust and dirt stirred up by removing the lens doesn't fall inside.

Most of all, don't store it too much. Get out and use it. Practice everything. Understand all the settings. Learn what you like and don't. Practice getting your images right and learning from the wrong ones. Have fun!!!

IQ difference between -A and DA 300MM lens
Posted By yucatanPentax

I was going to recommend the reviews, but of the A* also. Although being smaller, lighter, and less expensive (and not having AF), it does have some purple fringing at wider apertures and perhaps a bit less contrast, as reported by users.

You might want to borrow or rent a DA* 300 and try both on the same scenes to see if there is enough difference to justify spending the money.

Radioaktiv Lenses

The lens you are asking about was produced after thorium oxide was no longer used in lenses. Probably no one has tested it because Pentax no longer used any radioactive elements.

If you really want proof, I guess you could go to your local fire department HazMat unit and ask if they'll test the lens with one of their Geiger counters. Or buy one and do it yourself.

https://www.amazon.com/RADEX-RD1503-dosimeter-accuracy-radiation/dp/B005ZQ47...ger+counter%2C

You have to remember that even the actually "radioactive" lenses were mounted on film cameras, in very close proximity to film for days or even months at a time. Severe radiation would have fogged the film. So, even the known thorium lenses had very low levels. So low that they didn't fog the camera's film.

It's been said that if you held one of the thorium lenses to your chest for an hour, it might be equivalent to one modern day x-ray. That's pretty low, considering an x-ray is a fraction of a second, compared to an entire hour's exposure.

I'm interested in low-level aerials of various foreign places, especially where you cannot get back far enough on the ground to capture an entire facade or edifice. And I realize there will be all kinds laws and regulations to deal with in various countries....

But how to fly it?

He lost me when they were comparing photo quality on the LCDs of the cameras.

When he went to the monitor view of the images, the Pentax images were clearly richer and fuller. In the end, it was just too boring to watch. Including all the fiddling in the video, as Norm says, is just ridiculous, especially when he kept forgetting the flash trigger and didn't know how to set it. Really? You're including that foolishness in your video?

Toooo long and boring. Edit it down to 4-5 minutes and stop the music when talking.

My K-30 is still going strong after years.
You're just not to going hear much from people whose cameras are fine.
As far as all the surveys and estimates, etc, maybe it is around 20-30%, but that's just a wild guess, simply because the happy people don't complain, don't come online angry, etc. They're just out shooting photos. Since I ran across this, I thought I'd leave a positive comment.

Even if your camera aperture block dies, the camera still works fine for manual lenses, like M42s. There are some great ones out there, too.

Here's the thing that I've learned from a few recent personal experiences -- Tomorrow is not guaranteed.
So, I've become more focused on the here and now. And the people still around to enjoy and appreciate.

For some reason, that coincides with increased ire at the "Pentax is doomed!" crowd and apparently now comes the "What would you do?" crowd.
Look at current events. Does it appear any company's future is guaranteed?

"God laughs at those who make plans." Enjoy what you have or what you can buy today. Tomorrow is not promised.
Go out and take pictures. Take a few extra of the people you love.

Really nice images, Alamo. I'm impressed they actually found a way to add the second access for fire safety without making it completely ugly. Pretty decent solution.

And for those offering suggestions, I appreciate hearing them too, as I like to photography buildings and never can seem to get that wonderful look I see from better photographers.

re: Future of Pentax, i.e., "Pentax is doomed" . . .

I've been using Pentax digital for a dozen years. Every single year was full of "Pentax is doomed" naysayers online. In real life, people were making images. I just ignore it all.

One of our cars is 27 years old. Another is 61 years old. There are still markets for both of them and good demand too. The thing about digital is that the media doesn't vanish like film almost did for a while. (well, manufacturing dropped precipitously). One of these days, gasoline may not be available any more and then I'll really be up a creek. Or maybe I'll rip out the engines and install battery banks?

When I was using M42 lenses in the 1970s, developing my own b&w, there were magazine articles about whether Minolta or Konica or someone else would dethrone Pentax and Pentax might fall by the wayside. Like anything in life, use what you got, and let the future rest until it gets here.

If Pentax vanishes, don't you think there'll be a demand for that now unavailable, but legendary, K-1 or that great 150-450? Afficionados will always look for great gear.

Anyway, might as well worry about North Korea wiping out Seattle or Fairbanks. There are infinite worries about the future. Focus on today (except when saving for retirement - which may not come if you text and drive).
