there are the following ideas:
1.Identify the main requirements: First determine what your most important needs are in aerial and sports photography. Are you looking for higher image quality and detail or easier operation and control? Do you need to improve autofocus or expand the shooting range?
2.Evaluate existing equipment: Review the specs and features of the camera body and lens you are currently using to determine their limitations and advantages. Understand their performance in terms of maximum aperture, focus speed, image stability, and more.
3.Lens Priority: Aerial and sports photography often require the use of wide-angle, telephoto lenses, or lenses with special features, such as image stabilization. If your lens options are limited to meet your photography needs, upgrading the lens can bring more significant improvements, improving picture clarity, field of view, and stability.
4.Body Performance Considerations: If your camera body requires more powerful features, such as faster burst shooting, higher resolution, faster autofocus, etc., or you need more control options to handle complex photography scenes, upgrading the body may be a more appropriate choice.
5.Budget constraints and balance: Consider your budget constraints. Generally speaking, lenses can cost more than the body, so it may be more economical to choose an upgraded lens when your budget is limited. However, if your body features are very limited and cannot meet your needs, then an upgraded body may be indispensable.
