About TLS800 by Swarovski

Question 1
Just wonder if it is possible to have metering functions still in place (e.g. the centre-weight auto or centre-weight manual) using a TLS800 along with Swarovski ATS 80 on a Nikon D200 body.
Interestingly, Swarovski did not provide a definite answer for that.
I was given to understand that this TLS800 is in the screw mount form, so a Nikon mount is needed for locking onto the D200.

Question 2
Another question is: what aperture should be used for making corresponding shutter speed adjustment for exposure?

I have been using the TLS800 recently with a Canon 400D, I set the camera to Aperture priority mode. The TLS800 needs a "T mount" adaptor (around HK$150 ) in able to mount it on the camera.

The TLS800 is a f10 lens but just set the camera in A mode and it selects the fastest shutter speed, you will find that you may need to increase the ISO in cloudy conditions

These are a couple of shots I took yesterday on Lamma Island with the TLS800

Just fantastic shots. Thanks for them as well as the information.
Bother you with these two more:
1. According to your experience with other digiscoping friends, does that metering functions still preserved on a Nikon D200 like what it does on you Canon's?
2. Is it that the focal length will turn out to be 1600mm on an APS-format DSLR?

Dear tbob,
I copied this from Swarovski for its TLS800:

[highlight=red]Functional temperature: -20?C/+55?C (-4?to + 131?F)
Storage temperature: -30?C/+70?C (-22?to +158?F)
Submersion tightness: 4 m (13 ft): when mounted on scope (filled with nitrogen)  

  TLS 800
Focal length (in) 31.5
Length, approx. (mm) 141
Length, approx. (in) 5.55
Weight approx. (g) 240
Weight approx. (oz) 8.45
Focal length (mm) 800
F-number CT85 9
F-number for all ?65 12
F-number for all ?80 10
Camera fit T 2 [/highlight]

What do these stand for
F-number CT85 9
F-number for all ?65 12
F-number for all ?80 10
Camera fit T 2 [/highlight] ?

Regards,
Peter

Peter,

These figures are the f stop when the TLS800 is used with different models of Swarovski telescopes. The CTS is a collapsable telescope, the 65 is a 65mm telescope and the 80 is the 80mm telescope.

The T2 mentioned is the adaptor I mentioned above, Swarovski do not sell it but it should be available from an large photo shop. You would need a "Nikon mount to T2 adaptor".

Regarding the exposure metering I can see no reason why the various metering functions would not work, but I don't have a D200 to check.

Regarding the focal length on my Canon the focal length is 800mm x 1.6 (the crop factor), so it is equivalent to 1280mm.

I have experimented using a Canon 1.4x extender on but it is necessary to put tape over the pins on the extender otherwise the camera will not recognise the lens. But it works

Peter,

This is a shot taken at Kowloon Park using the Swarovski 80HD scope, Swarovski TLS800 and Canon 400D

Thanks for the information and the beautiful shot. Swarovski is really good glass. The color transfer is awesome.
The attached is a an Egret I took this afternoon at about 4pm. It is very far away and much smaller due to the framing effect I intended to attain, but evidently, the plumage details are much less than the one I saw you post here in this forum. Glass is glass and mirror is mirror. Obviously, if one does not intend to rely on the big gun to shoot objects that are relatively more static, the fieldscope is an investment that is money for value.

Peter,

Remember just because you have a very long lens it doesn't mean that you can pick out the details on distant birds. Hong Kong's polluted air and heat haze are against you getting good results. Try where ever possible to get closer to the bird (of course without disturbing it ) and watch and learn their habits so that you can anticipate what they are going to do next.

Happy digiscoping

Bob

PS: I hope you don't mind but I tried getting a little more detail out of your shot

Certainly not.

Swarovski TLS800 adaptor

I use the adaptor on my Fuji S5 with a Nikon mount (same as the D200).
For the Nikon D200 you can like Fuji S5 choose a Non-CPU lens in your menu.
However I cant see it is making any difference.
If you select the menu you can see the data in your viewfinder and it should give you the choice to select spot or center-weighted metering.

I think Bob is on the payment list at Swarovski with those photos he can make.
You can find my photos (not much) at my Flickr website and also read my comments in the album.

Steen, I wish I was, actually I have only been digiscoping since April 2006 and I just bought my 1st DSLR, a Canon 400D, a couple of months ago. Its a new hobby for me

Swarovski TLS800

Some people are born with the talent.  :D

I know you practice a lot.

I enjoy your photos with or without TLS.

This is good news. Actually, I have been using non-CPU lenses on my D200. The kinds of metering opened to in D200 are good enough for revitalizing the good old days' manual Nikkors. Obviously, the T2 plus the TLS800 are worthy of possessing, despite the fact that they are a bit too expensive (HK$3700), along with the ATS 80 to make it part of the repertoire of the DSLR system.
