Canon EF 75-300mm
Reddit take
AI summary of the Reddit excerpts below — not a quote
The Canon EF 75-300mm is overwhelmingly regarded by the Reddit community as one of the worst lenses Canon has ever produced. It is frequently described as 'garbage,' 'infamously bad,' and a 'waste of money' due to its outdated optical design and poor performance on modern digital sensors. While it serves as a very low-cost entry point for beginners, the consensus is that its flaws in sharpness and speed make it a frustrating tool for most photographers.
Pros
- Extremely affordable entry-level telephoto option
- Functional for absolute beginners learning focal lengths
- Capable of producing acceptable results for small 4x6 prints
Cons
- Poor image quality and lack of sharpness at all focal lengths
- Slow and noisy DC autofocus motor
- Significant chromatic aberration (purple fringing)
- Lack of Image Stabilization (IS), making handheld long-range shots difficult
- Outdated 1990s-era optical design
Caveats
- The lens was designed for consumer film stocks; high-resolution digital sensors make its optical weaknesses much more apparent.
- Often bundled in 'kit' deals, leading many beginners to own it without realizing its reputation.
Best for
- Absolute beginners on an extreme budget
- Users who only need low-resolution images or small physical prints
Avoid if
- You want sharp, high-quality images
- You can afford the EF-S 55-250mm, which is widely cited as a superior alternative
- You shoot moving subjects that require fast autofocus
- You frequently shoot handheld at the 300mm end without a tripod

Yeah for sure avoid the 75-300. It is a waste of money.
Definitely not the 75-300 that one is terrible.
75-300 is ass. Anything with a DC AF motor is slow.
I really can't advise the 75-300 at all.
I have the 75-300 and it's garbage :(
The 75-300 is notoriously poor in image quality.
I’m steering him away from the 75-300 due to it’s basically the old 1990 one.
All versions of the 75-300 are a must avoid unless you are desperate and can't afford the ef-s 55-250.
Your 18-55 kit lens and the 75-300 are a couple of the worst lenses you could have for image quality.
it came with the EFS 18-55mm and the EF 75-300mm which were fine as a beginner but I've definitely outgrown them.
