We take the new Canon 24-70 f/4 IS and put it up against the existing 24-105 f/4 IS to see if the new 24-70 is worth the upgrade.

The Canon 24-70 f/4 IS is here and sharper than ever. Also part of this new upgrade was a hefty price upgrade, not so much from the retail price of the 24-105mm f/4 IS, but because the 24-105 can be found at greatly reduced prices due to the packaging of this as the kit lens in so many Canon cameras. Either way, the Canon 24-70 f/4 IS is now here and here to stay so let's take a look at the performance this has to offer.

LearningCameras puts the new Canon 35mm f/2 IS against the new Sigma 35mm f/1.4 to see which is sharper, focuses faster, and offers better performance and value. We also test test these lenses out on the new Canon 6D camera as well as a Canon 5D mark III.  

A review of the new Canon 35mm f/2 IS lens. This pricy lens offers image stabilization combined with a wide prime lens. Take a look to see how this new Canon lens performs.

Can the new Sigma 35mm f/1.4 hold its own against the 40% more expensive Canon L lens? And can a cheaper, 3rd party lens actually beat the longstanding Canon champ in sharpness, build, and focus speeds? LearningCameras puts these two lenses side by side to see which one is the greater of the two using some of the best DSRL cameras in the business. 

A review of the new Sigma 35mm f/1.4. This lens offers some amazing abilities for a fraction of the price of the Canon & Nikon competition. But can Sigma compete with the long standing build quality, focus speeds, and sharpness from the big 2 manufactures?

There is an obvious lack of wide aperture lenses for Canon & Nikon’s 50mm equivalent focal length for cropped sensor cameras. While canon has some great L lenses in this category such as the 24mm f/1.4L and the 35mm 1.4L, these lenses are often over $1,500 placing them out of reach of most prosumer camera owners. Sigma has come to the rescue though offering quite a few lenses in this range, most notably though, the Sigma 30mm f/1.4.

With great specs, solid build, and reasonable pricing, can the Tamron hold its own against Canon & Nikon's pricier rivals.
