RE: Long macro lens
no lens with ANY 2X TC is ever going to approach the performance of ANY Pentax dedicated MACRO Lens, TCs suck, all they do is magnify/project a central portion of the primary lens, even if they were perfect you are not going to get nearly as much contrast nor resolution as a primary MACRO lens of the same focal length without the 2xTC in place. The matter is even worse with APS digital than it is with FF film because you are then using an even smaller section of the lens circle and blowing that up again... jco -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Adam Maas Sent: Wednesday, April 23, 2008 2:34 PM To: Pentax-Discuss Mail List Subject: Re: Long macro lens This is a 2x flat-field converter specifically matched to the Tamron 90mm f2.5 Macro lens.

Re: Long macro lens
Barry, You bring up the question about how she is working... My experience is that you must have patience.

RE: Long macro lens
Barry, I thought I'd offer my 2 cents' worth here. I've had the Sigma for about 2 1/2 years now, and am quite pleased with it's performance. It has become my most used lens for both macro and general nature shooting. I wanted to mention, though, that after about a year and a half, the diaphragm jammed in the stopped down position. Nothing I could think of in the field would restore it, and it went off to Sigma. They repaired it under warranty, of course.

Re: Long macro lens
Just to add to the confusion (after desperately trying to enable a new lens for the guy), I have seen work from the Tamron 90mm macro and the matched multiplier, and was very impressed. A friend had this rig and did some comparisons between the lens with and without the converter, doubling the distance with the converter to keep the reproduction ratio the same, and the results were nearly indistinguishable from one another at an 8x10 print size. This was on film mind you, but if the lens is good on digital, I expect the lens and matched multiplier should be good on digital as well. I recall at one time I saw a set of extension tubes for Pentax that had A contacts which would make things much more usable on the current cameras. I don't for the life of me recall the brand, other than that they weren't Pentax. Neither of these solutions will be as good as a real macro lens, but they will be a lot cheaper, and may be just fine for your wife's purposes too. I remember years ago I had just bought myself a 300mm f/5.6 Tamron lens, one of the old stove pipes. We were being swarmed by Monarchs, so I stuck an entire extension tube set onto the LX and put the 300 on the front and proceded to chase butterflies around the yard for a roll of film. The working distance was around 10 feet, perhaps a bit more, and this was almost filling the frame with butterfly. I got some lovely pictures that blew up nicely to 11x14 William Robb - Original Message - From: Bill Sawyer Subject: RE: Long macro lens Barry, I thought I'd offer my 2 cents' worth here.

Re: Long macro lens
Barry, I would start with a 200mm and a set of extension tubes. This would get her close focus and some interesting pictures. Results can be suprisingly good!

Re: Long macro lens
Barry - Pentax forte for some time was macro lenses. Lots of other good glass, but macro seemed to be an area where they really did things just right to get a superior product. (Others would argue that their 77-85 range is equally good; I would have a hard time disputing that claim. The 50mm lenses have been another special niche.) I have had substantial experience with the M (or was it A?) 50/4.0 and the A 50/2.8. And the M 100/4.0, and the A 100/2.8, and FA100/2.8 and the DA 100/2.8. And the FA* 200/4. Not many of the later were produced, those of us who own them are not likely to let them go. But if you should find one available, run, do not walk, to the nearest bank to arrange a third mortgage, or sell your car, or otherwise rearrange your finances as needed to be able to buy it. Any of the 100mm plus 2x should also do the trick, but you will degrade the image somewhat. Any of the 200 or 300mm lenses, with a short tube to bring the close focus point nearer will do ok, but you won't get the Pentax macro quality and you will lose autofocus. I think the most realistic option is to go for the DA 100/2.8 which is on the market and will give good results. (If you can live with manual focus, my A 100/2.8 is on my to-be-sold list. If a DA* 200 came along I might let go of the FA*, but for now it is on my to-be-buried-with-me list.) stan On Apr 22, 2008, at 5:48 PM, Barry Rice wrote: Hey Folks, My wife is becoming increasingly interested in photography of flighty, skittish, and sometimes dangerous animals, such as butterflies, reptiles, and snakes.

I realized that the ideal lens for her would be something like a 200 mm 1:1 macro. Even better would be if it were autofocus. Is there anything like this that would fit her *istDs? Or are we in a fantasy land that I couldn't afford? Currently she uses my 90mm Tamron, but can't quite get close enough with that lens.
