The circular effect is achieved by zooming out to wide setting using B-300 1.7 teleconverter. Circular vignette is what I wanted here but usually a major disadvantage when using an adapter lens of smaller diameter than the 717's lens.

Bill, your presentation of a "circular" view of the Liberty statue reminds me of a coin...& I like how you placed her to one side in the composition. Neat shot...what are you looking thru? MFC
