I have a question for those out there who have the Canon 7D Mark II and the Sigma 150-600 mm sport. Do any of you who have this set up experience a little slop between the lens and the camera. I notice when I pick up the camera and lens together there seems to be some movement of the connection. I may even have noticed that some focusing may be lighter or darker than others while not even changing a setting. This is not noticeable very often but I suspect the terminals not properly connecting between the lens and camera. Slop is noticeable say when I pick up the camera by the camera body or even gripping the camera foot when I have it adjusted so it's on top of the lens when shooting. When I grip both the camera and lens and twist I can feel a movement although small it concerns me. My other telephoto a Canon 100-400mm L II does not show this movement.

I have a Sony HX50v same limitation as the Canon SX models. To achieve a Bokeh like suppressed background, I use fast shutter, low ISO and flash. Since the flash is not adjustable, I use tissue or distance to adjust the intensity.

These conditions suppress the effect of the ambient sun light since the shutter is fast and the sensor does not see sun light very long and the low ISO means that the sensor is not sensitive. Using f-8 further dims any thing not close to the subject. Summary: subject is bright, background is dark.

With a little Post the background disappears. The suppression involves boosting black, lowering green luminosity and saturation. Not true Bokeh, but as you can see background but it is very visually suppressed. This is what my Manual setting goes to when the camera is set on M. This is my favorite for photographing flowers.
