    Ultra Wide Angle Eyepieces on PF-65EDII

    I'll be interested to hear how they turn out. I first decided on the WO based on a glowing review I read. However, I changed my mind because of the eye relief issue. I settled on the Baader Hyperion as the widest eyepiece with sufficient eye relief. Eye relief specs are notoriously...

    Ultra Wide Angle Eyepieces on PF-65EDII

    Yes, I'm using it with my glasses. The view is pretty impressive without them. If I really jam the eyepiece against my glasses and turn my head just right, I can almost see the field stop. It's not comfortable though. I saw an ad in one of my photography magazines from Hoodman. They have...

    Ultra Wide Angle Eyepieces on PF-65EDII

    I just ordered a Pentax PF-65EDII from BuyDig.com. They've got them for $400 with a 20-60X zoom eyepiece. http://www.buydig.com/shop/product.aspx?sku=PKPF65EDII I assume the eyepiece is the XF which doesn't have enough eye relief for me. So, my plan is to resell the zoom and buy some fixed...
