p.1 #1 · p.1 #1 · First Impressions: TAMRON 24-70 VC (A007E) on 3rd Party Body

Received my Tamron 24-70 VC lens (Model A007E, Canon mount) on 4/26/2012 - the world first full-size, high speed standard zoom with built-in VC and moisture-resistant construction. I am posting my first impressions with some snapshots - none of them are serious work.

-- Size and handling
Although with 82mm filter size, the lens does not look too big and matches my 5D Mark III. Zoom ring is very tight. Thus, the zoom lock is not necessary. Zoom direction is different from that in Canon lenses. I do not like the shape of the hood.

-- Focusing
works well on my 5D III. I did do some microadjustment after initial tests. I do not have a method to measure the focusing speed but it seems reasonable.

[email protected], Microadjustment + 8:

-- Sharpness/IQ
Overall, very impressive. Perhaps a little bit soft at 70mm f2.8 but still usable.

70mm @F2.8, 4.0, 5.6 (left to right, cropped):

70mm @F2.8, 4.0, 5.6, 8.0 (top to bottom, near center, 100% view, applied same amount of unmarked sharpenning):

-- VC or Image Stabilizer
I was often questioned by wisdoms since I purchased the EF 24-105 F/4 L IS a few years ago: Do you really need IS in this zoom range?! Yes, I do and I am aware that there is ISO settings, equipment like tripod, and IS won't work for moving objects, etc. However, I still find the IS/VC is very useful in many circumstances, where I have to use 1/15 sec or even lower speed. This A007E has at least 3 stops IS and I could use up to 1/6 sec with confidence.

Frankly, the VC is the most interesting feature to me. I would purchase EF 24-70 II, just for piece of mind

if Tamron 24-70 did not have the VC.

70mm @1/2 sec (cropped, handheld combined with continuing shooting technique):

-- Vignetting
I do not like the darker corner "feature", which is obvious when shooting at a garage door or wall a few feet away. I do not use a CPL and the "feature" remains unchanged with or without the hood.

Light, object distance and of course, decreasing aperture can improve the lens vignetting dramatically.

Wide end performs very well and the vignetting is much less even at f2.8.

Bokeh ([email protected], cropped. It could be better @2.8 but I do see some onion in 100%, not in all out-of-focus lights, a few only.):

For whatever it's worth, here is a same shoot using EF 70-300 L IS (Both of them are cropped but not identically. The exposure is also different.)

Seriously, many people are very interested in this lens. You could really be an asset to the FM community if you would not rush to post. Please take your time. I hope to see more.

I am very interested in this lens as well. Would really appreciate a review when you have had a chance to use and evaluate it.

Thanks

Don't really understand the title and pictures don't seem to be showing up? Hope the Tamron turns out to be a great lens. Let us know if you see the onion ring pattern in out of focus areas.

That's some serious vignetting at 70mm of the garage door

. The other shot taken at the same setting seems to be OK and everything else seems to be fine, at least as can be seen on JPG websized images. Thanks for posting!

The vignetting looks atrocious, still, though, interested to see more from this lens.

That one (fig tree) was cropped.

Fortunately, you can see the dark corner through 5D III's view finder, reminding one of being more careful

Thank you. What is wrong with the hood? How do you define "reasonable speed"?
Let us see some 24mm shots too, please.

Yup, that's the one and it was cropped, huh? Then the vignetting is definitely serious then

. Yes, it can be adjusted in LR but to what extent without any other ill effect will remain to be seen.

I am not sure what software you are using for those images. LR does a great job in taking care of vignetting issues. Could you do that for us then, please? Meaning try to remove the vignetting using LR or whatever software you have, post the full size image and an enlarged size of the area that you corrected for vignetting? I fully realize that the sensor behavior will play a role in the enlargement but at least it will give us some insight on the optical performance of that lens. Thanks again.
