How about APS-C with Horse 150-600 "Bird Hunting"?

APS-C compatible horse 150-600? Shoot birds? How's it going?

APS-C frame is what we often call a half-frame machine. In fact, there are some machines that shoot birds in the half frame, and the ecology is quite good.

I have seen some photographers buy half a camera to shoot birds and other subjects when they have Quan Huafu. I think the best cameras to shoot birds are Nikon D500, Canon 7D and 90D. The focus and continuous shooting of these cameras are invincible, and the picture quality is quite good, no less than some full-frame cameras.

Sigma 150-600 lens is the best choice for many photographers to shoot ecological birds. It is the most rational choice to use this lens when you can't buy a long fixed focus.

Sigma's 150-600 is divided into two versions, one is the C version and the other is the S version. C version is a popular version, suitable for ordinary enthusiasts, and the price is slightly cheaper. S version is a sports version, which we can understand as a professional version. The lens is better than the C version and the price is higher.

You can choose the lens you can afford according to your preference for eco-photography.

It is actually the best choice to shoot birds in half a picture. Generally, the focal length will have a coefficient of 1.5 or 1.6, so that we can earn enough focal length and shoot birds more ideally.

Therefore, it is a good choice to adapt the C format to Ma 150-600.

APS-C uses this Sigma 150-600 lens, and there is no problem shooting birds at the focal length. If you are just a bird-hunting enthusiast and don't take commercial photography, the picture quality can meet your requirements. The only thing that feels a little weak is that the shutter speed and focus pursuit in continuous shooting are slightly insufficient. Then again, you get what you pay for. After all, it is not 1DX plus 600, is it? ?

Finally, resolutely resist the encouragement of luring birds.

The above suggestions are for your reference. ?
