[QUOTE="918v, post: 1218630, member: 84964"] I owned a 3-15 F1 and a 5-25 F1. The 3-15 glass had good resolution and contrast, but the image through the ocular looked narrow. There was a pronounced black ring at the extreme edges. It was like looking down a pipe for lack of a better term. But it was easy to set up and very forgiving in terms of focus and parallax. Then, stupidly, I sold it in pursuit of better glass after looking through a S&B 5-25. Not wanting to spend $4k on a SnB, I spent $3k on a 5-25 F1. At first I was very impressed. The image quality was superb. It was very sharp and contrasty. The knobs were a lot crisper. But I soon started to see some issues. For one, the parallax was extremely sensitive. And it changed from day to day. On Monday it could be zero at 75 yards and on Tuesday it could be at 105 yards. Second, I could not set the ocular to get a crisp reticle, sharp image, and no parallax at the same time. I either had no parallax and a soft image or a sharp image with a little parallax. I sent it in but was told the scope was fine. This was my first scope with these issues. No problem with my other scopes. So I sold it. Since then I bought a Kahles 6-24 and a SnB 5-25 and neither scope has these issues. One of my family members bought the 4-16 F1 and experienced multiple turret problems that facilitated a prompt sale. My scope was from the first run and current scopes might have these issues worked out. [/QUOTE]
