Pentax K100D
Check out Ben's first digiscoping results with the Pentax K100D!

Digiscoping with point-and-shoot digital cameras (what I do) may become a thing of the past. As the evolution of point-and-shoot digital cameras seems to render them increasingly less digiscoping friendly, I have fewer cameras to suggest to people who email me requesting a recommendation. In fact, I can't actually recommend a single "in production" point-and-shoot digital camera for digiscoping. It's pathetic that digital camera manufacturers have not embraced the digiscoping technique, and they probably never will because it's not where the money is.

Lately I've been reading the Yahoo digiscopingbirds group with great interest by those coupling DSLRs directly to the eyepiece of their spotting scope. Some digiscopers, including Clay Taylor of Swarovski, have been getting pretty respectable results employing this method. My co-worker Ben Lizdas recently attended the Space Coast Birding Festival and was so impressed with seeing Clay's setup and results firsthand, he purchased a Pentax K100D DSLR to use with his Leica spotting scope.

Ben's new Pentax camera arrived today and I had only a few minutes to tinker around with it before he leaves for another birding festival tomorrow morning. When Ben returns, I should have more time to run the setup through more rigorous testing, however I was also impressed with how easy it was to setup and use on a Swarovski spotting scope.
Most of you know I use either a Nikon Coolpix 995, 4500 or 8400, all of which are discontinued. These are the only digital cameras I've used extensively for digiscoping birds. This makes it difficult for me to recommend anything else. Rather than make a blanket recommendation, I'm merely going to state that this new setup works pretty well.
I took the Swarovski/Pentax setup outside and took three quick pictures of an amazing chance encounter of a Tundra Wood Knot (from about 35 feet away). I used a complete manual focus (camera on manual focus, focusing exclusively with the spotting scope's focuser). It's still bitterly cold here and I didn't allow any time for the scope to acclimate to the outside temperature, so the focus looks a little soft. This picture was resized, unsharpmasked (120:1.1:1), slight level increase and made the colors just a tad warmer:

The Pentax K100D DSLR is combined with a Pentax 40mm f/2.8 lens. This lens has a 49mm accessory/filter thread. A 49mm-52mm stepup ring is required to connect to Swarovski DCA (digital camera adapter) configured with the 52mm adapter ring. This should work similarly with either Kowa's DA1 or DA10 digiscoping adapter and a 52mm adapter ring. If you're not going to go with a Swarovski or Kowa spotting scope, then whatever digiscoping adapter you get needs to come out to a 52mm thread (using the step ring).

I'll preface my so-called recommendation like this: If all my present digiscoping gear suddenly vanished (all three cameras), I would probably replace it with this setup. But for now I intend to keep on using my Nikon Coolpix 995 until it dies. Perhaps I'll switch over to my Nikon Coolpix 8400, but I still haven't figured out how to get its white-balance to render accurate color.

So what might be the cost of this setup?
Sam,
Naturally, prices are subject to change without notice:
Swaro HD 80mm: $2,099.00
Swaro Zoom: $489.00
Swaro DCA: $219.00
3130/3021 Tripod: $228.00
Pentax K100D: ~$600.00 (body only)
Pentax 40mm f/2.8: ~$230.00
49mm-52mm ring: $15.00
Total: $3,880.00
Spending the next several years capturing nature's splendor with the finest digiscoping equipment around? PRICELESS
Five years ago my entire setup (Swaro, 995, tripod, etc.) was around $2,800.00.

I realize you had a very limited amount of time to play with this set up, but I'm wondering how you liked looking through the veiwfinder, vs having a live LCD display to look at. (I'm assuming that is how you digiscope, plase correct me if I'm wrong.) I have always thought that the live LCD on a P&S for digiscoping was a big advantage over looking through a viewfinder, but I could be wrong.
Mike
This is a great setup! Way back when I got my KOWA - TSN scope, I had the option of getting a nikon mount for my SLR!! I never expected 12 years later that I would have some regret for not getting it! I wonder if I could find that mount on Ebay somewhere??
Mike, thank you for reviewing this set up. Is the unsharpmasked (120:1.1:1) done in Photoshop. What is the 120:1.1:1 measurement?
Best regards,
Len (a fan from NH)
I'm used to a view-finder from film SLRs. I like it.
Adobe Photoshop unsharpmask:
Amount: 120
Radius: 1.1
Threshold: 1
These are the values I use prior to resizing an image.

Looks like a neat setup! This year Olympus is expected to release a pint-sized E-410 DSLR with "Live View" that allows use of the LCD screen as if it were a point and shoot; aspects of this (a 10x digital zoom, for instance) could prove handy for fine tuning manual focus on perched birds.
So there was no vignetting with the 40mm Pentax lens?
I would still be most delighted if some effort went into designing a "digital" photo adapter that coupled to DSLR's via a T-mount and yielded ~800mm/f6 equivalent on a 1.5x crop sensor, rather than the very difficult to use ~1500mm/f12 equiv. that is available for most scopes. I probably wouldn't replace my digiscoping setup with it as it is a pain to change eyepieces, but there are plenty of days where I never take my camera off the scope. Plus if folks want to they can slip teleconverters in the mix for more reach...
Thanks for the test images!
Should have showed what the viewfinder looked like.
Anonymous,
This wasn't a camera review, but an article about the effectiveness of a particular DSLR for digiscoping. I supplied a link to dpreview’s review of the Pentax K100D. If you click on it, you'll find the photograph you're looking for.

Hi Mike,
Any further news in regards to the effectiveness of this set-up.I own a Pentax K100D and a PF80EDa scope and I've tried coupling the DSLR with no lens directly to the scope eyepiece (XW20) with limited success and I've just ordered a 50mm f:1.7 lens for the K100D to try your set-up... You seem to think this is the way to go.
Robert
It's effective with a Leica scope. Check the recent post regarding Ben's first digiscoping results with the Pentax K100D.
Mike
The Pentax 40mm f/2.8 is a pretty big lens. Did you have any trouble with vignetting?
Peter
There is no vignetting.
Mike M.
Mike,
I am a novice at digiscoping and found your posting on the K100D with 40mm lens very informative. I bought the camera and lens for use on a Swarovski ATS-80 HD scope. Would be willing to share some camera setting tips, to help me get started?
Thank you,
I am surprised you were able to pull this off with no vignetting.
Are you or anybody familiar with such a setup for a Canon 30D?
"The Pentax 40mm f/2.8 is a pretty big lens. Did you have any trouble with vignetting?"
Huh? It's one of the smallest lenses i know of, how did you come to this conclusion?
This looks like a very neat setup, possibly even better with the K200D when it's released as this reduces the amount of non weathersealed equipment in the configuration.
I have a Pentax K100D and recently bought an Opticron Scope and the 41114 Photoadaptor and the 41115 Eyepiece for attaching to my Pentax
camera. I have treid all manner of settings for my set up and cannot get a decent, sharpely focussed picture. I notice that in your set up you use a 40mm lens - do you suggest I change the Opticron set up and look for such a lens ?
Mike H
Mike H.:
I haven't had the opportunity to use an Opticron spotting scope. Not knowing the quality of how it would compare next to a Leica or Swarovski leaves me at a disadvantage in providing you a reliable answer.
Cheers,
Mike M.
