During the New Jersey Camera show I was able to get my hands on four lenses to test out: Tamron SP 35mm 1.8 Di VC USD Lens, Tamron SP 85mm 1.8 Di VC USD Lens, Sigma 85mm 1.4 DG HSM Art Lens, and the Sigma 50mm 1.4 DG HSM Art Lens.
The first one I tested out was the Sigma 85mm 1.4 DG HSM Art Lens which is the newest addition to the Sigma Art line. I've actually heard about the art lens and its pretty popular brand of lens among photographers. I saw some examples of them and was impressed by the image quality. I had the opportunity to try them out while attending New Jersey Camera Show.
I shot these with my Canon 70d at f/1.8, 1/200 sec, iso 500
I was obsessed with this lens and spend my time shooting around. The images came out nice, smooth and sharp and produced a nice bokeh. If you shoot portraits like myself this would be a great addition to your collection. However it is on the heavy side than most primes lens. But I didn't mind the weight.
The next lens I tested out was the Sigma 50mm 1.4 DG HSM Art Lens. This lens was introduced two years ago. It has the same bulky feel like the 85mm. I shoot these images below with the same settings. The image quality was impressive and clear.
After testing out the Sigma Art Lens. I ventured off to test out the Tamron Lens. I haven't heard too much about this brand. But I heard there in competition with the Sigma Art Brand and when you compare price to the two brands, the Tamron is cheaper.
I first tested out the Tamron SP 35mm f/1.8 which has Vibration Compensation for full frame. Vibration Compensation is another a term for optical stabilization which is delivers sharp focus on subjects when camera shakes from holding it due to its sophisticated glass.
I only shot two of my best images but have to say I was fascinated with the quality and the sharpness the lens produced. I like the consistency and the accuracy of focus of the subject in the images.
Next is the Tamron SP 85mm 1.8 Di VC USD Lens which is known to be the fastest fast-aperture lens with image stabilization. It performs well in low light situations, delivers sharpness and a creamy bokeh separating the subject from the background.
Compared to the Sigma 85mm 1.8 Art Lens it is smaller. It is approximately the same size and weight as my Canon 85mm f/1.8 (Go to Lens). The shooting with the lens went smooth, fast, and accurate. Even from some distance it deliver some awesome clarity and sharpness.
Shooting with Lens will help the quality of your images. As far as the best route to lens to get is a stalemate. Both lens produces sharp quality images so you wouldn't be out of luck of choose over another but it also depends on your budget.
