Re: FA*200/2.8 matter again...

2002-11-08 Thread Alan Chan
I am about to give the 3rd one a try. Let's hope I don't break your record. 
Now the problem is, this lens is out of stock from B&H. I wonder if that 
means next year.  :(

regards,
Alan Chan

Bad luck? Out of four FA* lenses I've owned, three was faulty right out of 
the box. I'm now on my third 77 Limited. The first had some dust on the 
front element; not too bad but it proved it had been out of the box. 
However, it had some dirt, looked like some dried liquid on the rear 
element. When I tried to clean it I noticed it was on the inside of the 
rear element. I sent it back (the Pentax distributor claim the box was 
never opened by them and I believe it). The next one I had for almost two 
years and over that time a spot developed between the two back elements, 
turned out to be erosion of the SMC coating, due to the fact that they 
collided when focused at infinity. Instead of repairing it, they promptly 
gave me a new one that has been perfectly fine and is even better 
optically.

Did all these lenses you've had problems with come from the same store?


1 from a local retailer, 1 from Pentax Vancouver directly, 2 from B&H. There 
were some minor quality problems with my other Pentax gears too, but not as 
bad as this one. Boy, I need to take some drugs.  :(

Think of it this way. If you go to the zoo and want to photograph an animal
in its cage but there are bars between you and the animal, what do you do?
You open the lens up, put the lens right up to the bars and voila they
disappear. Now what you have are microscopic hairs and stuff on your 200mm
lens. If the lens makes big bars disappear do you really think a little 
dust
is going to cause a problem?
Get out there and use it, don't sweat it.

If it was dust, I wouldn't worry about it. But I was talking about the 
scratches which look like those on automobiles. You know, the millions of 
scratches after years of car washes.

I could accept a little dust, but any scratches, cleaning marks, finger
prints or similar are totally unacceptable, expecialy on a lense of that
price.

That said i've owned 2 FA* lenses and the glass has been fine in both, they
both did have a little dust in them though.

Did all these lenses you've had problems with come from the same store?

All quite true points Vic, but for Alan I'd say I would be upset because
that's some serious money for a * lens, and would expect it to be absolutely
perfect.  Again, I'm glad I don't test mind like that, and now don't plan
to...don't want to find anything wrong :)

I just brought the 28-105 Kiron that I bought "marked dusty" to my favourite 
camera store that does on-site repairs. Showed it to the owner. He checked it 
out and said not to worry. It was no big deal and would not do anything to 
the quality of the images. He knows I'm particular about things. There is a 
fair bit of dust (or whatever)  in the lens so your situation is probably 
absolutely nothing to get upset about. These lenses will pick up dust anyway 
so I wouldn't worry about it...

I cannot believe such bad luck.  I can easily see why you'd give up on them.
Now I'm afraid to inspect my lenses that closely and worried about the new
FA 20-35mm f/4 AL that is on it's way.  Pardon my french Alan but I'd go and
tear a Pentax a new a*e over this.  FA*..bad

Hi Rob,

There is some dust inside this 200mm, so to the 1st one I returned. However, 
what concerns me is the scratches present behind the 1st element (on 2nd or

not circular. It definitely looks like cleaned by hand. When the light was 
pointed from different angle, cleaning marks were revealed too (but totally

scratch inside, but this 200 has a lot. All my other Pentax lenses are fine

Hey Alan,

I've come up against the UNKNOWN FORCE myself.  FA 28-70 f/4 AL with a bent
aperture blade, waiting 10 years for a CS-130 cable release, waiting 3
months for a Macro Lens, and it looks like another month+ wait for another
lens.  I hate the UNKNOWN FORCE, and if possible will kill it.
