LX/circular or linear polarizer
It¹s slipped my mind . . . Does the metering system in my LX require the use of a circular polarizer or will a linear one work nicely. Thanks, RW
Tokina 800mm F8 screwmount
Does anyone have experience with the 800mm F8 screwmount? I could use it with the adapter on my K-mount cameras for wildlife, if it is sharp enough. I make 8x10s, 11X14s, occasional 16X20s. I might be a lot better off to get Pentax¹s 1,000mm SMC F8, even though it will cost a lot more. RW
Pentax 1,000mm F8 K lens
Thanks for the data on the optical quality of the Pentax 1,000mm F8 lens. Would anyone know what one would one go for in mint condition with case? RW
1,000mm F8 Pentax lens
Does anyone have any experience with the Pentax 1,000mm F8 SMC K-mount lens? I understand it¹s fairly rare. Is it sharp? RW
Pentax 1,000 F11 mirror lens
How good is the Pentax 1,000 F11 lens? RW
photodo lens tests
Does anyone know if photodo still tests lens? There have been no updates since June 2000. RW
8mm Sigma fisheye/exposure
Just picked up a used 8mm Sigma F4 fisheye. I suspect that because a circular image is produced in the middle of the neg and no light reaches the edges of the neg, I must deviate from in-camera light meter readings (using LX, ME Super, MZ5-N)??? Perhaps, the best bet is to shoot a roll of film and bracket the exposures to determine how much compensation is required . . . or use a hand-held light meter. RW
fish-eyes: Sigma or Zenitar?
I¹m pondering buying a not-too-costly fish-eye lens as it will not be used a great deal. However, I would like something capable of producing sharp 8X10-inch prints and, once in a while, an 11X14. Does anybody know how good the Sigma F2.8 multicoated Sigma XQ filtermatic lens is? I believe it¹s a 1980s lens. Perhaps, I¹d be just as well off to buy a new Russian Zenitar lens??? Does anybody have experience with either of these lenses? Thanks, RW
35mm F4 schneider radiogon
I picked up an interesting lens in beautiful condition on eBay a 35mm F4 Schneider Radiogon preset screw-mount lens. I suspect it was made in the early ¹60s, but that¹s a guess as I haven¹t been able to find out much about it, other than it¹s fairly rare. At any rate, it will be interesting to use this lens on my Spotmatic, although I haven¹t a clue how sharp it is. Does anybody know anything about this lens, its optical performance, etc.??? RW
Tokina 24 F2.8
I notice there is a Tokina 24mm F2.8 lens for sale on eBay. With under three days left, it¹s at $75 US. I have one of these lenses and it¹s very, very sharp. Only negative I can think of is it takes 52mm filters instead of the 49mm that many Pentax lenses take. RW - This message is from the Pentax-Discuss Mail List.

Tamron SP 200-500 F5.6 lens
I¹m not sure how my Tamron SP 200-500 F5.6 lens stacks up against some of the other longer zooms being mentioned, but I¹ve been happy with mine. Manual focus and only available used, it¹s big and heavy a solid tripod is a necessity. I hope to use it plenty this summer as I¹ve had it less than a year, but negs from nature shots taken last fall seemed quite decent with an 8-times lupe.

photo.do tests
I¹m wondering if photo.do is still testing lenses as the Web site indicates no updates since June 5, 2000. I e-mailed them a while back inquiring about this but didn¹t receive a reply.

Tripod collar/K 300 F4
Does anyone know if someone manufactures a tripod collar that would fit my old Pentax K 300 F4? This is a big, heavy lens that I like optically but find extremely difficult to use on a tripod. My Tamron 200-500 F5.6 is heavier yet, but having a tripod collar makes it a joy to use on a tripod at least compared to my 300. RW - This message is from the Pentax-Discuss Mail List.

200 F2.5-1.7AF combo
I recently bought a SMC Pentax 200 F2.5 tele. I¹m wondering what sort of quality to expect with a 1.7AF convertor for my MZ5-N. I haven¹t bought the convertor yet.

Tamron 200-500 SP
Does anyone have experience and/or opinions on the Tamron SP 200-500 F5.6 zoom lens? I have a couple of other SP lenses (17 F3.5 and 90 F2.5), which deliver great results. When was this lens manufactured? RW - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
