    Comparison review of G9-ii with OM1 (presumably the second version): Niels

    comparison G9-ii and Om1

    Just for fun, I started making some calculations. Let us for a second assume you did have a 530 mm lens which on your camera would give you 800 mm equivalent reach, similar to what you would have with a m43 and a 100-400, and let us assume this is also a zoom so we do not have differences in...

    comparison G9-ii and Om1

    It seemed to me that there was advantages and disadvantages to both. If cropping, starting from 25 mpix would be an advantage; in low light I am not yet sure which one would be better. The reason I brought it up was to say this: if you can have focus between shots at 60f/s, then there is not...

    comparison G9-ii and Om1

    Regarding focus speed: G9-ii is able to give you 60 frames/sec with continuous focus during the burst. Pretty sure you cannot get close to that with your sony. There is even a new 100-400 which can take a TC; but remember, even without a TC you are up at 800 mm eq at the long end...

    Not really, but I can give a review of what I have picked up from several years of discussions and likely colored by my own bias. Most of the discussions center about either noise or depth of field. For noise, the two main things that seems to influence this are sensor generation and pixel size...

    comparison G9-ii and Om1

    Are the other systems losing weight on shorter lenses too? Many people have argued that they need the full frame systems in order to get the paper-thin depth of field, but you only get that if you have the lenses with small F-numbers. Those lenses by necessity are heavy when you need to cover a...

    comparison G9-ii and Om1

    This is probably the first meaningful comparison I have seen. The video talks about some technical details that exist between the cameras, but for me the most important thing to hear was "No Winner - they are just so b..... good both of them". AF was seemingly very similar for stills and...
