What I mean by "bridge" camera is one that covers the gap between a dslr and a cell phone camera. For what I do in astrophotography my Canon 60D, 5D, 20D and 20DA do just fine with the 60D getting most of the assignments due to it's articulating screen. My current point and shoot, a Canon SX260HS is getting a bit long in the tooth having been acquired back in 2013 and now frequently displaying an E32 error which shuts it down, requiring a restart. (This indicates a slight misalignment due to a hit, dirt, etc. in the cog which extends the lens. This seems to happen at the most inopportune times. My cell phone camera is very versatile but does not have the pixel count/resolution for great pictures.
The Canon SX260HS is my family vacation camera and if working properly would be a good one for an anticipated African safari type vacation about a year from now. Additionally if a current camera has some capability for relatively short Milky Way single shots that would be great too. The Canon SX260HS at 15 second duration shots automatically only allows ISO 100 shots. For everyday use, and especially outside a long zoom is preferred. The 260SX has a 20X optical zoom. I do not think I need something that long, but a 3x to 4x zoom is not enough, so in short is there any point and shoot that is relatively compact meet the following specifications -
1) a zoom ratio from wide to low/moderate telephoto up to about 8 to 10x zoom
2) a bulb setting, or at least a long exposure of at least 30 seconds
3) an articulating screen
4) fast lens when at widest setting, f/2.5 or better
Looking at several now but none seem to offer quite what I want. Willing to spend up to about $800.00
Thanks for any recommendations!
