The ZWO-EOS-T2-Ⅱ adapter is made of two parts, an EOS-T2 adapter and a 5 mm length T2-extender. It is suitable for all ASI cameras.
This Version Ⅱ is nonadjustable and supports a Canon EF lens only.
When the EOS-T2 adapter is used without the T2-extender it is suitable for the 17.5 mm backfocus distance of the ASI cameras, such as the Cooled cameras and the ASI174, ASI294, ASI183, ASI1600, ASI533, and ASI2600 cameras. (Note: This excludes the ASI6200 cameras.)
When the EOS-T2 adapter is used with the T2-extender it is suitable for all 12.5 mm backfocus ASI cameras, notably the ASI120, ASI224, ASI290, ASI178, and ASI385 cameras.
You can use a 2-inch IR-CUT filter with the adapter.
