Lenses my dad left me

ecce38 · 09-11-2006, 03:20 PM

My father passed away some time ago but it wasn't until recently that I was looking at his old photography items. He had a Pentax KX camera with 2 lens. I've started shooting pictures with it and have gotten some good results. But I'm wondering about the lenses themselves. If someone could please give me some idea of how good theses lenses are, I'd appreciate it. Also, how well would they work on the new K100D? I just want to know what I've got on my hands here. Thanks. Here are the lenses and what's written on them:

1) SMC Pentax 1.4/50, 1505804 (not sure what these 7 numbers mean)

2) 4.5f/80-200 (around the edge of the lens it reads "JC Penny Multi-Coated
Optics, No.8243750.") Also, the word "Marco" is printed on
the base in a neon green color.

I can tell you they both will work on the new DSLR's the 1.4 50MM is it an M or an A. A would have the letter A on the aprature ring. This is a great lens either M or A. Not sure about the other but I am sure someone will answer

The seven digits is the serial number of the lens. Each lens has a unique serial number. The 50mm lens is a "K" lens, and will work in manual focus mode and Av autoexposure mode (you set the f-stop on the lens, the camera calculates and sets the shutter speed). It has a largest aperture of 1.4 which means that it is quite suitable for low-light photography.

The 50mm is great as a reversed lense for macro work as well.

It will tell you how to set it up in the "Custom" menu, and how this lens will react.

As other suggested, your lens will be in the "M" type lens category.

The best way that I found, to use this type of lens with my DL, is as follow:
a. In customer menu, set "AE-L" to be "Tv Shifted" (p.146, K100D manual)

When taking picture
1. Set the mode dial at "M" position
2. Select the apeture that you want
3. Hit the AE-L button, the apeture will close down and will read the light level and set an appropriate Tv
4. Compensate as needed (on my DL, I usually have to compensate between +1 to +2 EV, depending on the lightness of the subject.

Hope this help.

I "think" the 80-200 zoom will work the same was as the 50. I wouldn't expect the same high image quality from a JCPenny rebadged Chinon or whatever. They probably bought from the cheapest source just like Sears or Wards did back in those days. Make sure the diaphram blades move freely and the zoom and focus rings function properly. It is worth more as a keepsake than what you could get in trade or on ebay. Use and enjoy it.
