Tamron mirror lens on K10

For those who might be considering.

I purchased a 350mm Tamron mirror back around 1987 for specifically photographing damaged roof structures with several spotmatic film cameras that we used (still have those). It works well with the k10 and is also good for macro work if on a tripod. I have some test images over here

No tripod was used although I did set the lens on a nearby post for stability.

Very impressive!

What f stop value does this have?

I have a 500mm f 8 Russian screw mount which I love (when I can lift it!)

I'm not near my gear at the moment, in fact far away, but I believe it is f5.6, in fact sure of it. I recall it was not a cheap lens at the time. I've got a good selection of 1986-86 Pentax gear and lenses from my appraisal days.

Yep, I got one of those as well and it's 5.6. Actually I haven't really tried it on my dig yet, but on film it could do pretty good in some circumstances - I have taken some nice animal shots with that thing. Too much going on in the out of focus-areas means trouble! But that's typical of mirror lenses, not?

I have the Tamron 500mm "mirror" which I got off eBay for about 65 and for the money it's great. It has limitations for sure but for me it was the only affordable large telephoto. It came with the Tamron 2x converter which makes it very long indeed! Very decent pictures for almost no money.

Nice to hear from you. Eh, have you ever tried photographing the moon.
I can do this successfully, afocal method, through my six inch reflecting telescope, but I have a student in Florida who seems to do an excellent job using her fixed lens Canon, and using optical zoom. I tried this with my sigma 70 to 300 and it just does not cut the mustard.

But I have never tried my Tamron lens for this.
She seems to get good definition even when the moon is full moon, or almost so.

A slight focus issue which I am sure was atmospherics as the moon was a lttle too low in the sky.

this was with your mirror lens? without extender? impressive.
guess I will try my lens when I get home. One of the problems with my sigma is that it will focus past infinity,

What lens were you using to get that moon image.

well obviously you had less of a focusing issue than what I was having last evening, although the 30 below windchill was not helping matters either.

Plus I had street lamps to contend with.

I'm going to try my lens sometime when it is 1/4 moon, the cottage this summer, where I don't have to drive 30 minutes, to get away from city lights.

Light pollution is aproblem, but more so is moisture in the atmosphere, specially when the moon is quite low in the sky. Half moon shots always give better shots I think, due to shadows in the craters giving more depth to the picture. Of cours to get a half moon shot during an eclipse would mean being about 120,000 miles out in space, a nice trick if you can pull it off

yes, I own a six inch reflecting telescope that I built up in the late 1960s, and my favorite lens is a 28power erfle wide angle lens for viewing the moon. And it is best at about 1/4 to 1/3rd moon,,,,no sense even bringing it out during full moon, you would have to wear sun glasses.

I get fairly decent images shooting afocal method, just pointing the camera lens at the 28 power lens, using macro I believe, and doing it that way.

I'll have to set this up again this coming summer, and then fight off the mosquitoes, lol
