Latest Review Posted	SMC Pentax-A 400mm F5.6 An affordable very sharp long lens. I bought it for shooting the eclipse and wasn't disappointed. I find making focus is easy with this lens. On my K-5 focus confirmation signal is very precise so I can even risk taking birds in flight! ... with about a rate of succes of 1 in 20. But for a slower moving subject I get really good results. The star field below was taken at f/5.6 and shows virtually no coma in the corners. It is a stack of several frames so it is slightly cropped. Without ED elements in the lens, you have to deal with a fair amount of purple fringing in PP and work on improving contrast The lens sure packs a lot of bang for the bucks. https://farm2.staticflickr.com/1557/25127978363_f65f8e3c63_b.jpg https://farm5.staticflickr.com/4458/24000569288_26f34d2fb8_c.jpg https://farm5.staticflickr.com/4513/37821520042_cac30e4cf3_c.jpg https://farm5.staticflickr.com/4499/37595810960_c7f39e9aec_b.jpg https://farm5.staticflickr.com/4447/37853994021_434affb1f5_b.jpg
