Getting back to the Pentax 100 ed spotting scope. I was able to do a side by side comparison between the Pentax 100 ed spotting scope and the Pentax 80 ed spotting scope and I wasn't able to, with my visual acuity, notice a big enough difference between the optics of the two scopes. I used the same Pentax 20-60 zoom eyepiece for each scope and fixed on the same object at various distances. The difference was so marginal that I felt the added weight and bulk and especially the added costs (approx $400) didn't warrant my buying the 100 ed scope. So I purchased the 80 mm ed. I know later on I won't look back and doubt my decision especially when I'm hauling a much lighter scope into the field. Also, I used several fixed size eyepieces with similar results. All eyepieces were Pentax products. Now, I need to do some research to find the proper setup so I can do some photography using the 80mm. I have an Olympus C 750 digital camera with a fixed zoom (the lense dosen't come off) that I would like to adapt to it. Does anyone have any suggestions?
