Thinner (11.5mm) EOS lens adapter needed for new EFW 36

gatsbyiv

The 12.5mm backfocus of the 2600MM means that we need a thinner EOS adapter that is 11.5mm thick. You have provided this for the 2" EFW, but many of us are using 36mm filters, so we need an EOS adapter that is 11.5mm thick for the new EFW 36 as well! Otherwise, the 2600MM + EFW can't be used with EOS lenses.

Hello
Thanks for the feedback
we will consider this

Sam@ZWO

the current solution would be a M54 EFW panel which compatible with the 2" EFW

Thank you for considering this. 2" filters are far more expensive than 36 mm, so the solution that you have for the 2" EFW is also needed for the 36mm EFW. This is not used only for EOS lenses, but also for many focal reducers where it is easier to attach a T-mount to the reducer than to thread directly onto it (for example, Takahashi reducers).

In the meantime, I will buy the QHY M42 EOS adapter (10mm thick) and add spacers.
