Testing the limits of the Panasonic LUMIX G9

I like to push all my gear to the limits if possible: weather, different shutter speeds, different lenses and different styles of photography. I want to start off by first stating that this camera fit in my hand like every other Lumix micro 4/3 camera I have shot with. The dials were all in familiar locations and the menus, well they were the same as my other Lumix models, except for some new upgrades.

The G9 did not disappoint on this trip. It actually out performed any Lumix camera I have used in the past. It performed well in low light situations where subjects blended into the environment and created some of the best dynamic range I have experienced in the Lumix line up to date.

Le Sony FE 200-600mm f/5,6-6,3 G OSS | Test Chasseur d’Images

Le Sony FE 200-600mm f/5,6-6,3 G OSS | Test Chasseur d’Images
Ce télézoom extrême, plus long que le FE 100-400 mm, permet à Sony de prendre encore de l’avance sur les concurrents (Canon et Nikon), en augmentant son offre d’objectifs en monture directe. Pour les EOS R et les Nikon Z, il faut passer par une bague de conversion.
Sony a fait le choix d’un objectif dont la longueur ne varie pas avec la focale. Les quelque 25 mm gagnés grâce à la monture courte pour hybride le permettent. La prise en main est bonne et l’agrément d’utilisation au rendez-vous — avec les boîtiers Alpha 7, un peu moins avec un Alpha à capteur APS-C. Pour améliorer encore ce point, on peut visser sous l’appareil une poignée accessoire. Elle facilite le cadrage en vertical.
L’objectif est vraiment bien construit. Les boutons fonctions et les réglages fins de la stabilisation et de la distance de mise au point sont autant d’atouts…

How to Check & Correct Your Autofocus: Tips for Fine-Tuning AF to Get Sharper Images

It’s time to sharpen up your pix. Modern DSLRs generally rely on what’s called phase difference autofocusing: basically, a rangefinder scheme updated with new technology. But as I described in the May 2018 issue of Shutterbug, this technology uses a second optical path within the camera, independent of the lens-to-sensor path used to make the photo.

Well, when there are two of anything, they’ll never be identical—excepting protons, electrons, and other elementary particles! Given manufacturing tolerances and the routine punishment you visit on your camera, it’s possible that these two paths are slightly different. Sure, your autofocus oughta focus. But it could be off.

Manufacturers are aware of this problem and often give you a way to “tune” or “microadjust” the autofocus. The adjustment is generally buried among endless camera menus, but a quick web search will tell you if your equipment has this capability.
