Tamron Di II A14E 18-200mm
The Tamron 18-200mm lens is praised for its versatility and value, offering a convenient all-in-one zoom range that eliminates the need to switch lenses. While image quality is generally good, some users report issues like softness at the long end, vignetting at 18mm, and lens creep, though these can often be mitigated by sending the lens to Tamron for adjustment or using simple fixes. Focus speed is adequate for most needs but can be slow in low light or live view, and the manual focus is noisy, which is a drawback for video. Overall, it is considered a great budget-friendly option for hobbyists and entry-level photographers.
Pros
- Versatile all-in-one zoom range
- Good value for money
- Decent image quality for the price
- Lightweight and portable
- Includes tulip lens hood
Cons
- Softness at 200mm end
- Vignetting at 18mm
- Lens creep when pointed up/down
- Slow autofocus in low light
- Noisy manual focus for video
