When buying a new lens, a common dilemma is whether to go for a native or a third-party lens. The third-party lenses are usually much cheaper, but how good are they? In this video, Jay P Morgan and Kenneth Merrill compare two standard E-mount zoom lenses for full frame Sony cameras: an $879 Tamron 28-75mm f/2.8 Di III RXD and a $2,198 Sony FE 24-70mm f/2.8 GM. How do they compare in terms of sharpness, image quality, and autofocus for both photo and video? Check out the video below for more details.
When it comes to the 24-70mm-ish range, there aren’t that many options for Sony. There’s the $2,200 Sony 24-70mm f/2.8 G-Master, of course. Or you could get the $1,300 Sigma 24-70mm f/2.8 Art lens for Canon and use the $180 MC-11 adapter. But wouldn’t life be better if you could do it for $800 with a native E-Mount lens? Something like the Tamron 28-75mm f/2.8 RXD?
To find out if it’s worth paying almost three times as much money for the Sony, photographer Dustin Abbott compares the two in these videos on the Sony A7RIII. The first of the two videos deals with the more technical side of each lens’s resolution. And some of the results are quite surprising.
Tamron couldn’t stop shouting about its new 28-75mm f/2.8 Di III RXD full frame lens for Sony leading up to its launch. I must’ve received a dozen press releases from them since the beginning of the year announcing its release. Now that its out, though, it seems that it has one big flaw. The autofocus randomly dies, requiring a power cycle of the camera in order to get it working again.
The issue was reported by That1CameraGuy during his initial review of the lens. But now, Tamron has acknowledged the existence of the problem. They don’t know what’s causing it, but they say that they’re trying to figure that out and that a fix will be coming via a firmware update which can be applied through the camera.
WPPI has been a good one this year for gear announcements. We’ve got the very impressive looking new Sony A7III camera and a whole slew of new E-Mount Art series lenses from Sigma. A couple of new entry level bodies from Canon as well as the new EOS M50 mirrorless. We’ve also seen a new AD200 competitor appear from Cactus who say it’s only just the beginning. Oh yeah, and then there’s that funny robotic speedlight from Canon.
There were a few items we didn’t cover, though. So, let’s have a look at everything that was announced. All the stuff we told you about and all the stuff we didn’t in one place.
If you’d like to pair your full-frame Sony mirrorless camera with a 28-75mm f/2 lens from Tamron, you’ll soon have a chance to do it. Tamron has announced that they are developing a fast standard zoom lens: the 28-75mm F/2.8 Di III RXD (Model A036), intended for full frame Sony E-mount cameras. They promise high-quality image, weather sealing and quiet autofocus in a lightweight lens. So let’s see the rest of the specs.
