Tamron 24-70mm f/2.8 G2 Lens Review

Introduction

Tamron 24-70mm f2.8 G2 lens is the latest lens to be released by the company, officially referred as ‘SP 24-70mm F/2.8 Di VC USD G2 (Model A032).’ It follows in the footsteps of other great lenses developed by Tamron which include 45mm, 35mm, and 15-30mm lenses. Although the lenses of the older generations had numerous issues, Tamron has been able to upgrade and redesign these lenses to meet the highest standards in the industry.

Among these achievements new full-frame zoom include Dual Micro-Processing Units (MPU) which provides ‘faster and more precise autofocus’ and improved the Vibration Correction system referred as simply VC also cancel out vibrations up to five stops. When compared to other lenses with vibration reduction for 24-70mm focal length Tamron has developed a lens that surpasses every lens in the market for reducing vibration reduction.

Developing such a sophisticated lens also required an engineering feat that would require the assembly of 17 elements, of which two are extra-refractive, three are low-dispersion, and three glass-molded aspherical and one is a ‘hybrid’ aspherical element. All in all the lens has 12 groups and can focus up to 38.10 cm /1.25’.

Upon closer examination, the well designed Tamron SP 24-70mm F/2.8 Di VC USD G2 has nine circular blades creating a very creamy circular bokeh. The lens elements are treated with Tamron’s nano-scale ‘eBAND Coating’ to reduce ghosting and flare. On the front element, a fluorine coating has been applied to reduce oil and fingerprints markings.

Perhaps what makes Tamron SP 24-70mm F/2.8 Di VC USD G2 a unique lens when compared to Canon or Nikon is the ability for fine tuning AF and vibration control via Tamron’s TAP-in console dock which also allows firmware updates for the lens. In this regard, each Tamron SP 24-70mm F/2.8 Di VC USD G2 can be customised for professional use.

Image Quality

When it comes to image quality, micro contrast and sharpness are key factors to consider but also the accuracy of color renditions become equally important as 24-70mm focal range is commonly used by event and wedding photographers where skin tones must reflect natural appearance.

Our tests with Tamron SP 24-70mm F/2.8 Di VC USD G2 lens showed that the sharpness was better than Canon EF 24-70mm f/2.8L II USM when compared side by side in identical shooting scenarios. When we tested Tamron against Nikon AF-S Nikkor 24 – 70mm f/2.8 E ED VR, we found the sharpness to be better at the 24mm and 70mm focal length with Nikon, but at mid range of the focal length especially at 35mm to 50mm, Tamron was a little sharper.

We also compared the MTF charts for each of these lenses to determine whether Tamron SP 24-70mm F/2.8 Di VC USD G2 delivered results at the far end of the spectrum. The results were surprisingly good for a lens that is priced almost half the price of a Canon lens which not only matched but outperformed Canon in throughout the focal range.

Color Accuracy

Tamron SP 24-70mm F/2.8 Di VC USD G2 has a saturated and contrasty image quality. When compared side by side to Canon, we found images from Canon to be warmer in tones with slightly orange and magenta tint on the skin tones. This, of course, is in line with the character of all Canon lenses.

Tamron, on the other hand, delivered much more balanced skin tones with particularly correct colors in reds and violets. What we observed is that Tamron has more accurate color rendition that Canon’s 24-70mm lens. Of course, there are professionals who have used Canon lenses for decades who swear by them and find the warmer tones to their artistic taste. But we are comparing each lenses color renditioning into actual colors in real life as such we find Tamron to be of the most accurate.

The second lens we compared Tamron SP 24-70mm F/2.8 Di VC USD G2 to was Nikon AF-S Nikkor 24 – 70mm f/2.8 E ED VR which gave us very similar results. Nikon’s colors are accurate with a great amount of detail in tonal ranges which were also matched in images captured with Tamron lens. Overall, distinguishing these two lenses in image quality would be almost impossible unless detailed analysis with pixel peeping was performed.

Bokeh

Bokeh is a very important factor which is often misunderstood by novice photographers as the common myth that similar aperture on different lenses would yield identical results if similar scenarios were photographed. The truth is Canon, Nikon even Sigma lenses have great engineering design to behind each lens to create the most pleasing bokeh when the aperture is wide open. Yet, the results differ greatly because of the the fall off factor between the in focus and out focus areas.

When we tested Tamron SP 24-70mm F/2.8 Di VC USD G2 for bokeh, we found that there was a strong fall off from the in focus to out focus area which gave a three-dimensional quality to the images. This effect commonly referred as the three D pop is, one of the qualities we looked for in the images captured with Tamron SP 24-70mm F/2.8 Di VC USD G2.

The other factor we wanted to examine was the rendition of the bokeh in the out focus parts of the image. What we found in our tests was that images had a smooth, creamy bokeh. We believe that this is due to the aperture design having 9 circular blades. We attempted to capture images to see if nonagon (9 sided) or similar shape could be obtained. The results were of equal round bokeh when lights or similarly bright lit object were photographed.

Vignetting

Tamron SP 24-70mm F/2.8 Di VC USD G2 performs exceptionally well in handling vignetting. We tested Tamron at the widest aperture f/2.8 which had a minimal amount of vignetting then at f/4 and f/5.6; what the results were vignetting was gone by f/5.6 even at f/4 it was negligible.

Lens Distortion & Chromatic Aberration

When many elements are involved in lens design, they often aid the lens to correct some of the lens distortion. Tamron SP 24-70mm F/2.8 Di VC USD G2 has very minimal distortion at the shortest focal lengths when compared to its competitors, at the mid focal lengths the distortion is essential reduced to the lowest point. We believe that Tamron’s 17 element design helps to create a lens that has very little distortion.

Tamron SP 24-70mm F/2.8 Di VC USD G2 has a very little chromatic aberration, what we observed is when the lens is used at the widest aperture (f/2.8) shooting against bright object some chromatic aberration can be observed. This is to be expected from any lens that has a focal length of 24-70mm. What is important to note here is the fact that Tamron manages to control chromatic aberration as well as Nikon and better than Canon lenses in its focal range.

Stabilization

If there was one quality that stood out for Tamron SP 24-70mm F/2.8 Di VC USD G2, it is the up to 5 stops of stabilization that allows photographers to capture images without blur and shake. Our tests in low light situations showed that we could continue to photograph at shutter speeds of 1/15 without having issues with accurate focus. This goes a long way in helping photographers achieve amazing results in low light circumstances.
