Just to echo the remarks about fast primes, while my first lens after the kit lens was a Vivitar Series 1 70-210mm f/2.8-4 v3, the next one was a Pentax-A 50mm f/1.7. I find myself using it more than another other lens, even today.

In the end, what matters is whether the client likes it. :)

Agreed. Get a metal lens hood and forget the filter. And remember you can use a deeper "tele" hood on a 50mm, due to the 75mm FOV on Pentax DSLRs.

I use a Bogen 3046...like the one Lester Bogen is sitting on here:
Seems stable enough. :lol:

The smaller the f-number, the faster the lens. Or said another way, the larger the aperture, the faster the lens.
Edit: For example, a 50mm f/4 macro is a reasonably slow lens; a 50mm f/1.2 is 3-1/3 f-stops "faster."

Great computers, those Amigas. I still have an A500, an A1000, and an A3000 around here someplace.

Give her both options, but add one more: add the yellow back into the center of the daisy, while keeping the rest b&w. She might like that.

The other night, I found that 5-6 seconds was about right for minimizing star trails and maximizing exposure, with a 50mm lens. Obviously, the wider the lens, the longer you can expose before trails become apparent. I have a star drive, but couldn't be bothered to hook it up that night, since I was in the middle of town. I just wanted to see what I could do with a K10D in all the ambient light pollution.

Here's my recent attempt:
The "Sagittarius Star Cloud." Milky Way near Scutum, with M11, M16, M17, M24, and M25.
K10D, ISO 1000, A-50mm @ f/1.7, 8 seconds

I would think that you could catch some on bulb, like waiting for lightning strikes. 'Course, they're not nearly as bright, and therein lies the rub: if the shutter is open long enough, at an aperture and ISO great enough to catch them, the frame will probably "fog" with ambient light before catching one.
Still, don't cost nuthin' but time.

I've never used PS plug-ins, but your post sounded interesting (and I was bored). I'm using Gimp 2.4, and placed the pspi stuff in ~/.gimp-2.4/plugins, and I made another directory, ~/.gimp-2.4/pspi and placed a PS plug-in in it. Registered the directory with xtns:Photoshop Plug-In Settings. The first time didn't work as I had only placed the .8bf file in the directory. Adding two .dat files that came with the plug-in solved that.
So, in other words, it worked for me. I suggest starting the Gimp from a terminal window, so you can see what errors (if any) are being generated when you click on the plug-in in the menu.

Great shot! Mind posting the EXIF info on that one? And maybe a description of your PP work? Thanks!

...And yet, they didn't fare as well as Hoya in this spectrophotometer comparison:
UV filters test - Lenstip.com
My take is that years ago, UV filters offered the transparency film (slide) shooter a real advantage, especially when shooting in open shade. Slide film's sensitivity to UV caused many such shots to have a bluish overcast. Today, I never use filters of any sort except for one-off special-effects work. I buy Pentax lenses (mostly) for their color rendition; why would I want to alter that? But, YMMV. ;)

I am "right-eyed," also known as right-eye-dominate. I close my left to shoot (both cameras and rifles), but I'm right-handed, too. My daughter is right-handed, but left-eyed. Makes for some interesting contortions when shooting a rifle. :eek:

Right. Typically, the advertised guide number is for ISO/ASA 100, in feet or meters. But not always. Some less scrupulous companies used to "fudge" their guide numbers by advertising the ISO/ASA 200 guide number, without specifying, leading unsuspecting consumers to think it was more powerful than the competition, who used ISO/ASA 100.

Be sure and check the trigger voltage. Some older flashes can damage modern DSLRs.

Excellent! Please consider photographs of the operation, too. You could make a "how-to" article. One that I personally would love to see, as I just bought a 44M that looks exactly like yours, but has a fairly "gummy-feeling" focus ring that probably needs to cleaned and lubed. :)

Looks like a more modern-ish version of my old Spiratone 400mm f/6.3 or Cambron 500mm f/8 (plus zoom function, of course). The lack of aperture ring is odd, though. Even my Cambron can stop down to f/22.
Edited to add: That Bower weighs more than twice what either of mine do...1.5 lb vs 4.4 lb.

I just noticed the iphone screenshot. WTH? Focus point in the example is 5ft 26in? Isn't that the same as 7ft 2in? Or 86 inches? What kind of weird, illogical, un-intuitive interface is that? :hmm:
