Metal-bodied, manual focus third-party lenses have exploded in the last year or two. This review checks out the new 50mm f/1.2 lens from TTArtisan made for Sony APS-C cameras.
If you love a shallow depth of field and image quality isn’t a prime concern, there’s a wealth of options available — and at very affordable prices. This 50mm f/1.2 from TTArtisan (the full frame equivalent of 75mm) is just $98 and at that price, you’d be forgiven for assuming that sharpness would be severely compromised. As this review from Arthur R shows, that’s not the case.
With the arrival of so many new affordable lenses, quality has improved dramatically, though more expensive lenses will offer significant improvements when it comes to corner sharpness and controlling chromatic aberration. Chromatic aberration occurs as a result of light traveling at different speeds through the elements of the lens which can create color fringing in areas of high contrast. More expensive lenses use low dispersion glass to avoid the phenomenon as much as possible, and then multiple elements to try and correct it where it does occur. There’s an excellent article on the B&H Photo website if you want to learn more about different types of optical anomalies and how lens designers overcome them.
