Whoa, lens arrived today. Just some first impressions:
ready to shoot (w/o caps, tripod-collar but with lens-shade) is 1215g. The lens-shade alone has 77g
- The lens is really easy to hold
once you've dismounted the tripod-collar. You can feel that it is lighter than many lenses of that size
- Only thing I'm uncomfortable with is the AF/MF switch
by pulling/pushing the focus-ring. If you hold the lens there during mounting or while aiming you might inadvertently toggle the switch. But it is easily reverted back. Just watch out that the switch is set correctly if you're in the middle of a heated session
is "pincer-type" just like Nikon's. Bravo Tamron!
is even worse than the Sigma type: it mounts only in one position and I cannot use it on my Nikkor lenses
Why that is, I cannot imagine!
- Doesn't extend
when zooming, doesn't rotate
when focussing (but that was to be expected)
- Both rings run smooth
but don't give you the feel of high build-quality.
- Overall the build-quality
seems below Sigma EX lenses. At least judged from those three EX-lenses I know. But nothing wobbles (so far).
- The zoom has no creep
- The focus-motor
is clearly not HSM/SWM/USM. It's louder and slower and sometimes it stutters when the focus is already close to optimal.
- I would have loved to have the zoom-ring in front and the focus ring towards the camera-body as I mostly use the zoom-ring and hold my tele-lenses at the foremost part (either the front-ring or even the sun-shade). So zooming requires some juggling with your left hand.
- And no: there is no aperture ring. Some of the information on Tamron's website suggested that the Nikon version might have a ring
- At 70mm with lens-shade on the built-in flash produces a shadow
in the lower fifth of the image
- The first impressions from the image quality
(IQ) look promising (phew!)
