judging by the quality you get (and probably expect) of your beautiful bird pics, I think you want to try and find a voigtlander 125, or a F / FA 100 (not sure whether f / fa is next best)

As far as I can tell, the only way to get a V. 125mm is to mug someone in the park.

Also add the Sigma 180mm to the mix.

I rarely go below 20 feet. Just have not had a need to for my kind of photography. I suppose I could add more extension but I would worry about collimation issues with all that plumbing hanging off the back end of the scope.

I have taken a few at less than 20 feet but not many...
I have wondered about the same thing, and also the vibration that is possible from the plumbing.

I guess the question is, can you put a bracket to go from the mount on the spotting scope to your camera tripod mount.

I have consiered the same thing for my C90.

can you post a photo of what the rig looks like presently?

by the way, very nice head shots. I'm not sure people understand what you have here, but this equates to a shot of half a dollar bill in total image size, taken at 20 feet.

I didn't include the Zeiss Makro-Planar T* 2/100 ZK because it doesn't achieve 1:1 without extension tubes and for such an expensive lens at 100mm this is unacceptable. my list only included 1:1 lenses. that and so far Zeiss K mount lenses have been notorious for having problems and needing servicing.

Vivitar 105 f/2.5 (and the Lester Dine or Kiron branded versions of the same lens)
is probably 98% as good as the VL 125, and cost less than half as much - but
they're just as rare.

I don't think anyone has mentioned the Sigma EX 70mm f/2.8 macro - probably
the sharpest lens in Sigma's lineup. I highly recommend it - longer than 50, but
still easier for handheld macro than the 100mm+ lenses.


Here are shots from the Sigma:








From the Vivitar Series-1 105mm f/2.5:



(ISO 800)


(ISO 1600)



From the DA 35ltd f/2.8 macro:








From the FA 50mm f/2.8 macro:








From the SMC-M 50 f/4 1:2 macro:



(Cropped)




As you can see, they're all optically pretty great. I'd say pick your desired
focal length based on what you'll be doing and whether or not you want
to use it as a general walkabout or portrait lens also, and then choose
from the above!

added to the list. sigma seems to be stacking up rather well against pentax I would say.

Nice comparison series. I wouldn't call the Viv 105mm rare. If a person is willing to spend the money they are around and can be had. The VL 125mm on the other hand it will take some effort to find and it will be 2 to 3x as much.

Voigtlander APO-Lanthar 125mm 1:2.5...

Sounds good but I can't find one in K mount. Any ideas where?
Find an owner and beat him to death. I think that's about the only way to get one now.

OK.
Here's the long and the short of it.

For me it's important to actually be out in the field taking pictures. I'm not willing to miss good shots while I go on a search for the holy grail of the perfect lens.

At this point I'm inclined to go with the Sigma 70mm. It's optical quality is as good as any and it has the advantage of being at a focal length where it could double as a "normal" hand held lens in certain situations. Given that I only have the kit lens below 500mm this is a real advantage.

Thanks to all for the advice.

Wildman

My attempt at a pseudo macro shot using the kit lens...

Macros

Wildman,

I don’t think you can go too far wrong with whatever macro lens you may eventually select Wildman. From what I have seen they tend to be good performers no matter who makes them. In my case I’ve stuck with the Pentax brand for all my lenses and I’ve not been disappointed. I have the M 50 f4 and A 100 f 2.8 macros. Here’s a shot from each lens.

A 100 f 2.8 macro




and one from the M 50 f4 macro



Cheers,

Tom G

Vivitar 105mm f2.5 is the best lens to go for.

oh, how could I have forgot the 200.

(hides head in shame
Easy to forget about, I think, as it is beyond my wildest dreams. The A-version is exquisitely expensive and the FA I never haven't even seen...

A little update...

The local newpaper that my wife writes for has a less than year old Sigma 180 macro that they want to sell for $400.

What do you think of the lens and the price?

I have the Sigma 70mm macro on order and am thinking of getting both of them. I think it would be a nice mix.


BTW...
not exactly a macro but I thought there would be some interest in what a Purple Finch looks like through a 1000mm long lens set up for prime focus at 60 feet. For those not familiar with this method that means there is nothing between the front objective (a 120mm two element achromat in this case) and the focal plane of the camera but air. Sometimes less is more.

I find it interesting that the new DA35 Ltd. didn't get more attention here.

Are https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/32664-theory-d...-ever-tag.html and
https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/32622-fa-35-da-35-a.html the only threads about it?

In German forum thread at DigitalFotoNetz.de :: Thema anzeigen - smc DA 35/2.8 Macro Limited this lens gathered an amazing flood of 1100+ posts which are 99% enthusiastic about the lens. 35mm is short for a Macro. But it allows you to "dive into" with your photography.


As for your scope images (which are really great!):
Which scope and which adapter besides the Pentax T-mount adapter did you use? And do you a focus motor on your scope? And if it is a Schmidt-Cassegrain, wouldn't it need a flat-field corrector lens?
And did I say your bird images are great?

I can't speak for the price, and as much as I detest Sigma on general principals, I have heard very good things about that particular lens.
