Digiscoping with Nikon D700?

Discussion in 'Nikon' started by Kulvinder Singh Matharu, Dec 5, 2008.

  1. I've been looking at using digiscoping for getting in close to
    subjects that are physically far away (particularly photographing
    birds).

    I have a Nikon D700 and I think that the following equipment may
    suite me:

    a. Nikon Fieldscope ED82 Angled Spotting Scope Body
    b. Nikon Fieldscope Digital SLR Attachment FSA-L1

    I have a good carbon-fibre Manfrotto tripod which I can use to
    support the above.

    Do you think that this is the way to go? Or should I be looking at
    other equipment?

    My budget is £1,000, maybe a bit more if there is a real benefit in
    spending that little bit extra.

    Thanks in advance!

    Not to be rude but the obvious first suggestion is to try what you have and
    see if it suits your needs. I doubt there is a reason to belabor the optical
    and mechanical differences between a field scope and a real telephoto lens.

    Thanks for this. I'll have a look at using telescopes.

    That is what I use and get very good results. It is much better than a
    telescope because the SLR attachment allows you to meter so auto
    exposure works very well. You do have to manually focus. Also EXIF data
    is preserved and accurate.

    You get a 1500mm lens, f/13 but it does very well in bright light. The
    sharpness is excellent.

    A telescope has limited uses because objects too far away will be
    distorted by the atmsphere. They usually will not allow close focus and
    the lenses will suffer from color distortion. The Nikon ED glass is
    excellent. The fieldscope does make a good telescope also and you can
    see Saturn's rings very clearly.

    Here is my setup (I use a D80):

    And here is a page of one day's photos taken with it:

    Here are other examples:

    I would not classify the Nikon Fieldscope with the SLR adapter as a
    digiscope. It is rather a 1500mm lens with everything but the autofocus.
    To me a digiscope uses the eyepiece of the spotting scope. This does not.

    Mirrored telescopes are very cumbersome, no? Can you swing them around
    easily and shoot accurately? Will the camera auto-expose? We're not
    talking about butting a P&S on the telescope's eyepiece. The OP is using
    a high end DSLR.

    The images I posted were all taken within 45 minutes of each other:

    http://www.netaxs.com/~mhmyers/fs-d80/index.html

    All I had to do was tweak the very large focus ring and push the button.
    No manually setting the exposure.

    Sure for astrophotography, a telescope is best but for nature and birds,
    like the OP mentioned, portability and auto-exposure is very important.

    Certainly enough here for me to think about both approaches.
    Portability is a key requirement...I've seen small telescopes and
    I've seen large fieldscopes.

    Was thinking of a purchase this month but I guess I need to do a bit
    more research!

    The Nikon DSLR connects to the Fieldscope with an adapter (FSA-L1) that
    *replaces* the eyepiece making the unit a true 1500mm (35mm equiv)
    telephoto lens. Do you understand this, or am I misunderstanding you?

    I still don't see how you get a DSLR to auto-expose with only a T-ring.
    You obviously cannot adjust aperture. You can only *manually* adjust
    shutter speed and ISO to get the correct exposure. This is *very*
    cumbersome while trying to follow birds or other wildlife

    The Nikon FSA-L1 will allow the camera's metering functions to adjust
    the shutter and auto-ISO so all one has to do is point and focus.

    If you are digiscoping with a P&S through a telescope eyepiece, the
    camera will autoexpose and even autofocus to a degree. But we are
    talking about using a DSLR body.

    You won't want to photograph birds with a mirror lens, the background
    out of focus will be a cloud of donuts. M-M's bird shots look nice with
    a soft background.

    I happened on an odd old 500mm f/4.5 lens, it is bulky and requires a
    monster tripod (came with it for $500 total, including some rust <g>)
    but it works pretty well. Here's the moon with stacked teleconverters on
    a D200: http://edgehill.net/Misc/moon/5-16-08 click for full crop
    M-M's moon looks better but not far off:

    Here's a crow across the street at 1000mm:

    Not bad!
    I can see that these are challenging shots!
