Re: More lens problems.
After speaking with Pentax USA and having no luck cleaning the contacts, I'm going to send them the *istD body and the FA 50, FA 100 macro, and the FA 135. Although it seems funny, they still think it might be the lenses even though they work on the MZ-S and the ZX-7. What really confused them was that the aperture wouldn't register AND the AF won't engage. I'll wait a week, however, so I can use the camera over the holidays (since it works with other lenses).

May I caution you to have everything insured yourself before you send it, with something like an all-risks policy. Pentax USA screwed me out of an thousand-dollar A* 200/4 Macro several years back. I sent it for repair, I never got it back, and Pentax in Colorado refused to file a claim with UPS. Luckily for me this lens was covered by my State Farm all-risks policy, which paid off immediately, or else I would have been left holding a very empty bag. I should have took my own advice recently. I sold a piece of gear on ebay, sent it uninsured because the guy declined to pay for the insurance, he now says he did not get it, and it looks like I will be out my gear and having to pay a refund.

AFAIK, it was possible to identify MZ-S bodies that are affected by entering Serial # at the following URL on Pentax Homepage: http://www.pentax.co.jp/japan/news/information/20010619-s.html I did try it two years ago when I bought MZ-S. Return info was that my MZ-S is clear. The unfortunate part of this is that, obviously, page is not available anymore. So this won't help you much, I'm afraid.

Re: More lens problems.
Steve, Do you have another ZX type body to try them on? I found that my FA 80-320 acted like it was not set to 'A' when I put it on the *istD. After putting it on the ZX-10 it behaved just the same. Pointing to a problem with the lens, not the body. After pressing and hold on the aperture ring right near the lens mount, it starts to read properly. Let go and it goes back to error. Also check for dirty contacts - body and lenses. Bruce Friday, December 19, 2003, 10:43:56 AM, you wrote: SD Obviously this is going to be a bad day The *ist D is not working with SD a few lenses.

I'm going to bring in my zx-7 for testing, although I know the FA 50 works fine on my MZ-S. I have cleaned the contacted, made sure they're on A etc. What's so odd is that three lenses now fail and that AF won't engage.

Go to a reputable dealer in secondhand goods, who will allow you to look at the object of your desire before you hand over your hard-earned money. £60 was way too cheap for a good example of that lens. You could offer the guy £10 for the extension tube and the hood, as it is unlikely that you will find many others. £120 is a good average price for an excellent example of this lens, with (I think) 12 months' warranty. Whatever Jessops ask, offer 10% less. Always works for me. mike

Re: More lens problems - crack in the glass?
On Tuesday I took an objective lens to pieces to find out why the pictures were milky. The problem was a deposit on the glass -- condensed grease. Its a bad idea to allow lenses that have lubricated helices to get hot. This one has a small diaphragm and rather small elements --one is about 2mm in diameter. It was quite difficult to clean them. Now the picture is fine. I did a couple of plan (focussing) eyepieces at the same time -- they were easier since the smallest element is about 15 mm in diameter. Again the problem was condensed lubricant to which dust and small particles were adhering; probably including small cellulose fibres from tissue used to clean (wipe) the exposed surfaces -- it gets down the barrel very easily during this process. But getting the four pieces of glass and the spacers back into the barrel and screwing it up without getting more crap in was difficult. These were all part of a large donation of 'redundant' equipment from the University; old perfectly good stuff no one uses any more. For examples of this 'close to focus' rubbish showing up on pictures look at: http://kotisivu.mtv3.fi/edfw/wild03/index.htm The same minute pieces of dirt on the eyepiece show up on almost every picture. It does not detract from the result, but makes the images look crappy. I hope that after my careful cleaning things will be slightly better. The human eye can cope with extraneous garbage in an image and 'process' the noise out, film cannot, and so the optics must be very clean. The nature of the imaging geometry is such that anything on the first transfer lens (eyepiece) is close to being in focus on the film. The human brain is one of the best (analogue) image processors that exist. I have another objective that looks like it has become delaminated. Delamination of cemented elements can sometimes look like a crack in the glass. When I can find some really clean Canada Balsam I'll do the repair. But I'll need to have a jig made that will hold the glass in line while the cement hardens.
