ZWO CANON M42 ADAPTER

$109.00 AUD
SKU: ZWO-EOS-T2-II

ZWO

  • M42 x 0.75 Male
  • Optical thickness: 31 mm


 

This ZWO adapter includes two parts (EOS to T2 adapter and 5mm T2 extender). It is suitable for all ASI cameras with a T2 (M42) female thread.

The EOS to T2 adapter without the 5mm extender is suitable for cameras which have a backfocus of 17.5mm such as ASI 174, ASI 294, ASI 183, ASI 1600, and ASI 533 (with the 11mm M42 adapter that came with the camera attached), as well as the ASI 2600.

With the 5mm extender the optical thickness of the adapter is increased to 22.5mm, making it suitable for cameras that have a backfocus of 12.5mm such as ASI 120, ASI 224, ASI 290, ASI 178 and ASI 385.

Note: as the free aperture of this adapter is smaller than the diagonal of a full-frame sensor, it is not recommended to use it in combination with full-frame cameras such as the ASI 6200 or 2400. 

This adapter is suitable for Canon EOS EF lenses only. Canon EF-S or mirrorless lenses are not compatible with this adapter.

To fine-tune the lens-sensor distance, the adapter include 4 round plastic shims with a thickness of 0.1mm, 0.2mm (x2) and 0.5mm.

Not for Pentax......But....

For the life of me, I couldn't find something like this in a Pentax K mount - plenty of adapters for adapting the PK camera to a T thread, but not a PK lens to astro cam. But, I did find an Urth Pentax K mount lens to Canon EF body adapter - which then fits this adapter so I can use my Pentax Lenses. There's a bit of fine tuning to be done - a Sigma 50mm Macro worked quite well without the 5mm spacer but with a Samyang 14mm, I had to add some thin spacers as the 14mm has a working distance of only a couple mm tolerance. Everything fits snugly and feels good quality. Add the fact that it has a thread for a 2" filter within the housing and you've got a very useful adapter.

Perfect

Shipped quickly as usual. Product very sturdy. Fitted a Samyang 10mm and achieved focus in the middle of the focuser range of motion. Very happy.
