Welcome to /c/birding, a community for people who like birds, birdwatching and birding in general! Feel free to post your birding photos or just photos of birds you found in general, but please follow the rules as outlined below.

  1. This should go without saying, but please be nice to one another. No petty insults, no bigotry, no harassment, hate speech,nothing of that sort! Depending on the severity, you'll either only get your comment removed and a warning or your comment will be removed and you will be banned from /c/birding.

  2. This is a community for posting content of birds, nothing else. Please keep the posts related to birding or birds in general.

  3. When posting photos or videos that you did not take, please always credit the original photographer! Link to the original post on social media as well, if there is one.

  4. Absolutely no AI-generated content is allowed! I know it has become quite difficult to tell whether or not something is AI-generated or not, but please make sure that whatever you post is not AI-generated. If it is, your post will be removed. If you continously post AI-generated content, you'll be banned from /c/birding (but it's obviously okay if you post AI-generated stuff once or twice without knowing you did so).

  5. Please provide rough information location, if possible. This is a more loosely-enforced rule, especially because it is sometimes not possible to provide a location. But if you post a photo you took yourself, please provide a rough location and date of the sighting.

Nice shot! I've been very pleased with my copy of that lens on an A9ii. Is this cropped at all? I've been missing the crop factor of my old aps-c body from time to time, especially for things like birds.

This is cropped slightly for composition but not much. It’s one of the reasons I got this lens, so I wouldn’t have to crop so much.

Is the A9ii a higher resolution sensor?

Thanks for the follow up. The A9II is a 24 megapixel full frame camera. It's probably best described as a sports camera since it's fairly fast at 20 FPS and has a fast reading sensor that lets you shoot electronic shutter in the majority of situations.

A smaller APS-C sensor gives you a 1.5 crop, which turns the 150-500 into a 225-750 on a crop sensor body. I started out on a D40 (Nikon APS-C) 15 years ago and ever since moving to full frame I've missed the crop factor.

Since the A9 series isn't particularly high resolution you can't leave that much on the floor. Cropping to 750mm equivalent would result in a 12 MP image. I've been teasing the idea of picking up a used APS-C body to use in situations where I want more reach and have been on the lookout for some good examples. This is a perfect comparison, thanks!
