About this product

Model:  baad_t-ring_2958550
Part Number:  2958550

The Baader zero tolerance protective Canon EOS T Ring is the BEST T Ring available for Canon EOS DLSR with EF bayonet fitting.

Offers a number of advantages over a regular T Ring:

  • Zero tolerance design optimised to fit Canon EF bayonet fitting. The result is a wobble-free T ring with no lateral play ensuring a stable image platform even for long exposures or during telescope slewing.
  • Designed to offer the largest possible free aperture resulting in less vignetting even with extremely short focal length telescopes.
  • T2, M48 or 2" nosepiece connections included.
  • Ability to accept Baader 2" LPFC (low profile filter cell) or unmounted 2" filters without extending the back focus.
  • Optional clear filter to protect your camera sensor from dust ingress (ideal for long exposures) and humidity.

Components Supplied

1. Protective T-Ring for Canon EOS body
2. Optional: Baader clear protective filter, 50.4mm x 3mm (protective T-rings are available with a range of pre-assembled filters. see below for details)
3. Temperature compensation ring (to prevent filter damage at high temperatures)
4. S52/M48 adapter ring (M48 corresponds to the international 2" Astro filter thread)
5. M48/T-2 insert ring
6. S52/2" connector socket (with additional 2" M48 filter thread on the front side)

Missing Part and Instructions
05 October 2021  | 

Although well made there was a missing temperature compensating 'o' ring and no instructions although they are available from Baader's Web site after some searching.

Versatile product, but has some play in camera adapter
22 March 2021  | 

I'm using this for my EOS 1DX mk3, with a low profile Optolong 2" filter. The filter fits inside the T-ring perfectly, and the grub screw clamp fitting for the S52/2" connector socket is firm. The only criticism I have is that the Canon adapter that screws into the camera body has a tiny amount of play in it, it is not completely rigid as with a lens. I've not yet tested this on a long exposure, but imagine that there will come a point where it has a slight bearing on the alignment of the sensor. Given that I want this for long exposures, it's not ideal - otherwise I'd have given five stars.

Very good T-ring
03 September 2019  | 

Having issues with another T-ring, from another brand, that was not fitting very well (there was some play when inserted in the camera body, causing tilting in my image), this one is a perfect fit for my Canon body (650D). The thing is in place and does not move at all.
Materials used feel solid and I have a good level of confidence when mounting my camera using this ring on my telescope.

I recommand.

Good quality but...optional filter?
13 April 2017  | 

This is good quality but be aware that when purchasing without a filter, spacing for the MPCC will be incorrect as the t-ring is mechanically thicker to account for the filter in the light path. The filter is optional only if you don't intend to use the MPCC with it. I wish I had discovered this before i purchased it.

Baader t ring
27 May 2015  | 

Very high quality t ring as you would expect from Baader. My only reservation would be that if you plan to change from 2" nosepiece to t-2 insert ring during an astrophotography session then this is only reasonably done indoors. Apart from this the adaptability and quality of this t ring is second to none.

Excellent piece of kit!
30 November 2014  | 

As expected a very well made and engineered product. Not cheap but it has the advantage of being able to connect to either a standard T fitting or an M48 fitting (ideal for SW field flatteners etc).
The best bit though is being able to fit a 2" filter in it (as long as it's no more than 6mm deep). So yes, if you need to know a Hutech IDAS D1 fits perfectly!
