Review/Impressions of Tamron 24-70mm G2 (2nd edition)

did you get a chance to see Dustin's review though? I think it's pretty honest, though I do wish he could of had a Canon II.

I sent him mine to compare - he should have an update in a few weeks.

that is the last place I ever look for reviews. he is to canon biased in my eyes.

One thing I've done is tested all the lenses I've owned compared to his charts then when I had multiple lenses I've compared to his charts and I've concluded that most of the time the 3rd party stuff behaves a bit better than what his IQ tests can show. However canon vs canon he is very accurate so I kind of use all of that together to make my own judgement based on my own experience owning lenses. I can tell when there just is absolutely no difference that you will be able to tell from his test charts when they are close. Even when they seem massive in the real world it's just not some kind of amazing difference.

How do you know if you have the 2nd version? Sorry for the dumb question,

DPR posted sample page...

isn't this a poor example of the starburst? The 16-35 2.8 III is much cleaner.

Thanks for this link - I own the Canon 24-70 F2.8 II, I have forwarded my copy to Dustin for his additional review / comparison, but this lens interests me because of the VC for my 5DSR.

I decided to go through most of the pictures, download a few, and really pixel peep, because when I first looked at them, it isn't exactly clear, in many pictures, what exactly the photographer was choosing as his critical focus point - and if I have learned anything from my 5DSR, it is very critical because the added pixel density makes it much more apparent what is in critical focus and what is not. Needless to say, most if not all the pictures he posted I don't think do a good job in representing the ability of the 5DSR for sure as he seems to have been very inexact with his focal point selection - that said, I did find this picture, that after I processed it a bit, shows that this is a fine lens, maybe not Zeiss micro-contrast category (but it is a zoom) but for pros doing event work it seems to be fine (I'm not commenting about the AF as I have no idea).

The other thing to note, is that not all images he posted were taken with the 5DSR - and the one I edited below was in fact taken with the 5D4 - as a 5DSR owner, I can easily see the difference in detail, and the AA filter effect, when I look at the missing detail in the child's eye - but overall, my preliminary guess is that the Tamron 24-70 F2.8 G2, is a more than capable Event lens, assuming the AF is solid.

This is a picture from the link that I spent 1 minute in LR doing some very basic adjustments from the raw download.

The spec on this picture are 1/250, F2.8, ISO 125. Unfortunately, from a DoF perspective, F2.8, at this distance to target, creates a rather thin DoF to analyze overall sharpness of a face, but the eyes are very good (not 5DSR good) and I like the colours after some processing (i.e. ISO 125 on the 5D4 produces excellent Canon colours)

Don't judge the sharpness on the image posted here, look at the flickr link for a better idea (but even then, my LR edit is sharper yet again). Based on this picture, I wouldn't hesitate on stating that this lens is sharp enough for Wedding work (again, no comment on the AF)

^^^ Thanks for test shot and your impressions. There's a lot of heresay going on this thread and it's refreshing to get some real data.

They are very different looking, the G1 has a gold ring and the G2, like the other new Tamrons that came out, have a modern sleek black look.

Chris Niccolls from The Camera Store just uploaded a comparison with the Sigma Art.

This is why I may pick up the Tamron:



if the timestamp doesnt work, fast forward to 6:27, I need a silent lens for video, and tamron is indeed very silent.... but who knows, by the time christmas shopping season hits, I may pick up another 24-70 depending on price. I'm not too concerned about IQ, as I plan on using for video, and incidental photography. I've already got smaller/lighter/sharpe​r lenses for landscape photography.

I watched the entire thing. Sigma focuses a tad faster than Tamron. Tamron is a tad sharper into the corners than the Sigma. This video is not a review. It is a sales pitch. "They're both good. Just buy one." I'd expect as much from a camera store review.

If you don't need LII IQ, and quiet video is your goal, why not 24-105 STM? About $900 cheaper than the Sigma, $800 cheaper than the Tamron.

I'm looking for a video lens for low light situations, zoom in particular. I already have a slowish lens for good light with sony's 24-240 f3.5-6.3, and it's quite good for that.

either way, I'm not going to pay the early adopters fee for the Tamron, I'll wait a bit to see the price settle. Right now, I simply use my fast primes for video, and it generally works well. I may test how well the 24-240 does in low light, but my confidence is not very high. I may test at the fair this weekend, as I'll be fooling around as my kids do some volunteer work. I'm still finding myself with video, not very good at it yet, but thought a 24-70 f2.8 would simplify things.

While that looks pretty good it was taken at 63mm and my experience with the VC model is it's pretty decent at 63 but took a hit at 70. I can also notice the eyelashes have a bit of ghosting and not very strong contrast. The sharpness on the eyes/lashes and surrounding hair/lips and such tells me this looks identical to the G1 or VC or whatever you call the first lens. I owned two copies... also owned the mk2 for a bit and now own much sharper glass in all. Those eyes could be better...

...but who the heck needs better... we are talking major pixel peeping.

Why do you keep going back to the G1? It's not relevant to the discussion, unless you make a direct A/B comparison to the G1. How do you know if there's issue at 70mm if you haven't touched the G2?

Now if you could get hold of a G2 and compare it directly to your MK2, now you're talking. I don't think anyone expects to G2 to surpass the mk2 IQ wise, but if the G2 is close, and if it's AF and VC are stellar, then it becomes a very good value proposition.

I ordered the lens today. I want it for next weekend's NYC Comic Con. Looking forward to giving it a go and will post pics that weekend.

Cool! Besides the IQ, could you also give your impressions on the AF speed and accuracy, particularly in low-light. Thanks.
