So a "26-108mm f/4.3"

Or rather a "26-105mm f4.2" Wink

Wonder how it compares to a Canon or Sony 24-105 f4 in term of size.
Bigger or smaller?
If bigger or the same, then going FF makes more sense.

Interesting at least for me... I still consider APS-C as my preferred format and still use it despite owning modern full frame body

At the same equiv specs, the dimensions/weight are pretty much comparable, too - plus/minus a bit.

Btw, it has RXD in the name, not RX D. RXD is Tamron's new motor style, like Canon's STM and Nikon's stepping motors (AF-P for DSLR lenses, no naming in the Z lenses (STM in their "specs"), as seen in the Tamron 28-75mm f2.8 Di III RXD.

Also, Tamron made quite a mess of their naming convention with "Di III". In the past, Di meant full frame SLR lens with better coatings for digital cameras, to prevent purple fringing. The later Di II naming signified that the lens had a smaller APS-C image circle. Then again a bit later Di III meant lens for mirrorless micro 4/3rds cameras. Then came the big mess, where Di III just meant "for mirrorless camera", whether the lens was for FF mirrorless Sony or for MFT. Now they added an "A" (Di III-A) to make clear it is for APS-C.

Tamron and their lens names have always been ... "special" ... lol.

It's 1.53x actually (I used 1.55)

So it's actually 26-107.2mm f/4.29 if we are even more nitpicky.

;-)

We are used to have interesting bodies with few lenses
Here it's the opposite an awesome lens but very few camera bodies. How many Sony E users we have ? make it available for Fuji or Nikon Z at least


RE: Tamron 17-70mm f/2.8 Di III-A VC RXD sighted - Klaus - 11-25-2020

Among the APS-C mirrorless users, Sony has probably a marketshare in excess of 50%.
You have to be really desperate for Z APS-C or EOS M.

Or Samsung.
I own a Samsung mirrorless camera and it's a pity they threw the towel in. It makes for a decent walkaround combo with the kit lens, and even if the system had not folded, I would have avoided buying more lenses as I have the Canon stuff for that. Got that camera dirt cheap from a co-worker and don't really regret it. It even got me a few "serious" shots I used in the workflow.

Now if only I could find the charger for my wife's old Sony NEX 3 that is beating around the house... Smile
