- T mount
- field flattener
Limited use so far, very sharp on both my Cannon stock 90D and the Ra. Still waiting OPT for my shipment of the T Mount for EOS from WO, but glad I have gotten the lense. I was able to get a mount that is very secure and await an optically clear front lense cover for the 55mm threads to protect the front glass from another well known suppler for the B+W glass. Picked up the saddle as well and both the lense and saddle were included in the carry case. FYI, case still has another cut block that can be removed from the foam block in the case to add additional storage, gave them a 5 Star, be hard pressed to lower
Excellent experience. Telescope is exactly what salesman described. Don was very helpful with the necessary information to help me make my decision.Scope is well made and easy to use. MB
Excellent Tele /Photo Lens. used it to shoot the moon last night.
In general, my experience with OPT was stressful, not because OPT but because the backorder situation. They solved my issue rapidly after speaking with one of the managers. Thank you for making this happen in a fast way. Waited for more than 3 months and was able to get it. Once again, thank you OPT.
