@ Heather: I don't know if you like MF lenses, but for longer macro's I use the A 100 f/4, which I'm quite pleased with. Maybe an alternative?
I've thought about going that route, as MF isn't a problem for me, but the only problem with the 100/4 is it has only the 1:2 macro ratio, whereas the 100/3.5 comes with a diopoter that takes it to 1:1. If there was a separate diopoter out there that would make the 100/4 a 1:1, I'd be open to something like that--perhaps one of the Raynox diopoters?

Alternatively, you could opt for an extension tube...

There isn't much room for you to play MF at a distant target. Good thing is, the AF is pretty fast when shooting something far
thanks. i'd seen the pics but was wondering whether it was manageable in practice.

i wonder why they did it that way - quick online inspection of marketing pictures indicates that neither the pentax 50mm macro nor the tokina 35mm macro is like that.

Because this thread has pertained to a swath of praise for the DA35, I must add a reality check. I just received mail back from Frank that the copy I used for one day to test and sent to him has a defective filter thread. Judging by the pictures, its clearly a faulty part. It wows in toward the lens in four 'corners'. I would highly suggest that as you receive your copies, you have a quick look to be sure yours is free from this defect.

We are now in the process of determining how to get this problem solved. Has anyone had any experience in having new lenses - imported from other countries - replaced by Pentax? Worst case scenario, we must ship it back to Canada from Singapore where I will take it back to the store, then ship it back at a cost of approx $100 to us in shipping. Any experience in this is appreciated.
Well, here is a photo of the lens:


I don't know how Pentax could let this pass through their QC, another case of bad QC in current Pentax product line

Wow... that is pretty bad. Is it worth it trying to round it out yourself?

Nope, the first thing I tried was to put a newly bought filter on when I took the lens out of box, but failed to screw it on no matter how hard I tried. That's when I found where the problem is ...

Here is another photo, you can see it's pretty bad to put a filter on:

Well, it suppose to be a brand new lens (still under 2 years warranty from Canada). I could try to round it but I don't think anyone would be happy w/ a Limited lens like that .

I do have a set of extension tubes--50mm worth. Would that be enough to take a 100mm lens to 1:1?

Tried it out and yep: you can go to 1:1...

@Frank: you mean you bought it that way? Seems like someone played with it and dropped it on the floor...

Yeah, it's like that when I took it out of box. But I don't think it's dropped or whatever 'cause the hood is perfect shape. Most likely it's some defect product out of the factory

But you have at least one year warranty, haven't you?

Thats our dilemma right now. See the original post with my story. Any tips? Either we ship it back and forth at our cost and risk for replacement, or ?

And no, it wasn't dropped. Its symmetrical wowwing (sp?) of the inner filter ring in 4 even places, not a bend on one spot on the barrel. It looks like some machine pressed it too hard in or something, hence my initial suggestion to have a look at your own copies to makes sure this wasn't a fault with a batch of these.
