Best Lenses for Aviation Photography: 100-400mm vs 150-600mm

Hey fellow spotters! I'm looking to upgrade my lens for aviation photography and would love your advice. Currently, I'm using a Canon 90D with an 18-135mm kit lens, but it's just not cutting it for those long-range shots at JFK (JFK) and LAX (LAX). I'm considering either the Canon RF 100-400mm f/5.6-8 or the Sigma 150-600mm f/5-6.3 DG OS HSM.

I'm interested in hearing from anyone who has experience with these lenses. How do they perform in terms of sharpness, autofocus speed, and overall image quality? I'm particularly curious about how they handle in low-light conditions since I love shooting during golden hour.

Also, how manageable are they when it comes to size and weight, especially for a day-long spotting session? Any thoughts on how they compare for spotting at busy airports with different viewing angles?

Looking forward to your insights to help me make the right choice. Thanks in advance!

I've used both lenses, and each has its strengths. The Canon RF 100-400mm is compact and lightweight, making it great for long spotting sessions without fatigue. It offers decent sharpness and autofocus, but its performance can be limited in low light due to the f/5.6-8 aperture range. On the other hand, the Sigma 150-600mm provides greater reach, which is fantastic at airports like JFK and LAX with distant vantage points. It's heavier, so a monopod or tripod is advisable for extended use. In terms of image quality, the Sigma delivers good sharpness and slightly better low-light performance. Consider how often you'll need the extra reach and whether you're okay with the added weight. Do you prioritize portability or the ability to capture more distant subjects?

I've had the chance to use both lenses, and here's my take. The Canon RF 100-400mm is indeed more portable, which is a big plus if you're planning long days at JFK or LAX. However, if you're looking for reach, the Sigma 150-600mm offers a noticeable advantage. In terms of sharpness and autofocus, both perform well, but the Sigma might give you a bit more flexibility with the extra range. Low-light performance is decent with both, but neither excels due to their aperture limitations. Personally, I found the Sigma's weight manageable, but it does require a bit more stamina. Consider what focal length you find yourself needing most often. Also, check if you can try these lenses at a local store to see which feels best for you.

I've shot at both JFK and LAX with a Canon 90D, so I understand your dilemma. The Sigma 150-600mm offers a significant reach advantage, which is particularly beneficial at these busy airports where you often need to capture aircraft at a distance. While it's heavier, the extra focal length can be a game-changer for those shots across the field. In terms of low-light performance, both lenses are fairly similar, but the Sigma might give you a slight edge due to its wider aperture at similar focal lengths. Remember, a sturdy tripod or monopod can help manage the weight during long sessions. Are you planning on doing more static shots or tracking fast-moving aircraft? That could influence your decision as well.

I've used the Sigma 150-600mm extensively, and it excels in reach and low-light performance. At JFK and LAX, the extra zoom can be a game-changer for getting those crisp shots of aircraft on distant runways or taxiways. However, it's heavier, and if you're planning long spotting sessions, the weight can become a factor. A monopod might be a good investment to alleviate this. In terms of autofocus, both lenses perform well, but the Sigma tends to be a bit slower. If portability is a priority and you're not always going for maximum reach, the Canon might suit you better. Have you considered a teleconverter for added versatility with the Canon?

I've used the Sigma 150-600mm at both JFK and LAX, and I can attest to its impressive reach and low-light performance, especially during golden hour. The autofocus is reliable and quick, which is crucial when capturing fast-moving aircraft. However, the lens can be quite hefty, so a good tripod or monopod is advisable for extended sessions. On the other hand, the Canon RF 100-400mm, while lacking in reach, is more portable and easier to manage without support for long periods. If you're often shooting from a distance at these large airports, the Sigma's extra reach might be more beneficial. Have you considered how much mobility you need during your spotting sessions? That might influence your decision.
