Focal Length and Versatility
The XF 70-300mm offers incredible zoom range from medium telephoto to super-telephoto, perfect for wildlife, sports, and distant subjects. The 33mm f/1.4 provides a classic 50mm equivalent field of view, ideal for portraits, street photography, and general use. The zoom's flexibility covers multiple shooting scenarios, while the prime excels in its specific focal length.
Aperture and Image Quality
The 33mm f/1.4 delivers superior low-light performance and dramatic background blur with its fast f/1.4 aperture. The 70-300mm's variable f/4-5.6 aperture is more restrictive but still capable, especially with its optical image stabilization compensating for slower shutter speeds. Prime lens design typically offers sharper results at its focal length.
Build and Practical Use
Both lenses feature weather resistance and linear motors for fast, quiet autofocus. The 70-300mm is larger and heavier due to its zoom mechanism and longer focal length reach. The 33mm is more compact and portable for everyday carry. The zoom's OIS provides 5.5 stops of stabilization, while the prime relies on in-body stabilization.
