Tamron 18-300mm F3.5-6.3 Di III-A2 VC VXD: Sony E-mount & Fujifilm X-mount
Posted by: pRICE cUBE

What's interesting to me about this announcement is that there is no version for Canon or Nikon's mirrorless lines. They both have fps-c MILC cameras that have been on the market for a few years.


[www.dpreview.com]



Tamron has just announced the 18-300mm F3.5-6.3 Di III-A2 VC VXD for APS-C. This superzoom lens will be available for both Sony E mount and (for the first time) Fujifilm X mount, raising the tantalizing possibility of even more third-party X-mount lenses in the future.

Covering a zoom range equivalent to 27-450mm in full-frame terms, the optically stabilized 18-300mm uses a VXD (Voice-coil eXtreme-torque Drive) linear focus motor, and "special lens elements arranged precisely to maintain high resolution performance from edge-to-edge". With a minimum focus distance of 6 inches, the 18-300mm can deliver an impressive maximum magnification ratio of 1:2.

The Tamron 18-300mm F3.5-6.3 Di III-A2 VC VXD is expected to be available later this year, but pricing information has yet to be released.

The Tamron 70-300mm f/4.5-6.3 Di III RXD is $499. Wonder how much more this new E mount will be.

Yea, but developing for Canon's APS-C M Mount seems like a dead end. If I was a manufacturer, I wouldn't bother. They might be planning an APS-C RF Mount if Canon ever releases one...

Come to think of it, I don't see any Tamron lenses with RF Mount. They all appear to be EF mount and need to use an adapter. Don't see any Sigmas either. One starts to wonder when/if they are going to start cranking those out...

Yeah, that’s what I said but I was too lazy to write Canon Rf mount and Nikon Z mount. I only referred to them as mirrorless lines.

Is the optical quality at all decent, compared with a prime? Not that you can buy good telephoto primes anymore....

The Tamron EF mount lenses of late have been getting very good optical reviews. This includes the 17-28, 28-75, 28-200 and 70-300. The first 2 are f/2.8 lenses.

Where can I find good write-up on the 28-200? I need a good travel lens for my 5D M3

Depends on your definition of “decent”. These work well for most general pics. If you have architectural lines or things like brick walls, you can sometimes see distortion (slightly curved line where things should be straight). All Superzooms of wide focal range exhibit degrees of this. I recent @#$%& some pics that had column in the background, I had to correct the distortion by about 6% I photoshop.

[www.bobatkins.com]

The left side image above show barrel distortion, some lenses show pincushion distortion which pinches inward. For many subjects, this doesn't matter. I am not sure what programs correct for this other than photoshop. Lightroom probably does and other newer photo editing programs. I know that correction for this lens distortion is on my ancient Photoshop CS 5.5.

I believe you're thinking of the RXD line, which are mirrorless lenses (for Sony E-Mount)?

There are Tamron EF-mount (Canon) versions of 28-75/2.8, 28-200, 70-300 but they are all really old. There is a more recent EF-Mount 17-35/2.8-4.

New mounts may have new licensing restrictions. So far, just to ragtag outfits like Viltrox are making a few.

I don't believe that has stopped 3rd party manufacturers before. Maybe they just haven't figured out the reverse engineering yet. Tamron making lenses for there Sony E Mount is a definite plus as Sony lenses are pretty pricy.

That's my understanding as well, that Canon and Nikon mounts are reverse engineered. I wouldn't have that RF and Z mount protocols would be all that different, but maybe they are?

I believe Sony actually provides 3rd party manufacturers with protocol information for E-mount.

I am not sure about Sony’s arrangement. If true, Sony is betting that 3rd party lenses can increase their platform popularity. Canon and Nikon are trying to protect their lens sales. I predict Sony will increase their MILC popularity at the expense of their competition.

Yes, the full frame Sony E mount lenses. They aren't quite as good as some of the more expensive Sony G or GM lenses but are very good for the money and in most cases the better choice based upon cost.

They are also smaller and lighter! I really like the 28-200mm as a versatile lens, even on the 61MP A7R IV, it does a good job, and it is smaller and significantly lighter than Sony's 24-240mm.
