|comment:||In the past few years i tried every superzoom i could get my hands on, first on Nikon APS-C, later on Sony APS-C, now on fullframe. I didn't like most of them and found only two above average: The Nikkor 18-200 VR2 on a D7000 and a Sigma 18-200 DC OS HSM2 on a A77. Neither was perfect, but they were capable allrounders. |
I didn't dare to hope for another good one on my A7r but luckily Tamron came to my rescue. The 28-300 is reasonably sharp in the middle of the frame, across the whole range and even wide open - and thats very (!) unusual for a superzoom like this. Stopping down to f8 improves the IQ further.
In the 70-300 range it isn't quite as sharp as the astonishing Sigma 70-300 I compared it to, but it comes close. I don't like the noisy AF, but the LA-EA4 adapter does a good job focusing. I will keep this lens as my new allrounder.
