I got the DH1758 and was able to try it out at the park. It takes some getting used to. It's unwieldy, particularly without a viewfinder. What I found is that I got the best results in DMF where I adjusted focus before releasing the shutter. Other than that, I think it will do just fine. The lighting was tough at the park because of clouds. I Shot shutter priority with Auto-ISO. The first shot was a whopping 1071mm using 2x Clear Image + extender (210mm * 1.5 (crop) * 1.7 * 2 = 1071mm).
