The 35mm focal length is one of the most commonly used by photographers, and it is a crowded space for manufacturers. Lens Rentals recently completed optical tests on Tamron's SP 35mm f/1.4 Di USD lens, and perhaps surprisingly, it has beaten out all of the competition.
35mm lenses are highly versatile and popular for many genres of photography, and there are numerous choices out there. In the past few years, Tamron has really jumped to the forefront of manufacturing, creating numerous high-quality lenses with quite competitive prices, though generally, the most expensive lenses tend to still hold the honors for top optical quality. However, perhaps surprisingly, the tide may be beginning to turn. Lens Rentals' Roger Cicala recently did MTF testing on the Tamron SP 35mm f/1.4 Di USD lens, and he calls it "for the moment, optically the best 35mm lens you can get, and at a price that should make you want to get it." While there are still other issues for photographers in practice, such as autofocus performance and bokeh quality, it's certainly a ringing endorsement for the lens and for Tamron. Head on over to the Lens Rental blog to read Cicala's full thoughts and test results.
