Samyang lost me with the weight on this one. If it had been lighter than the Tamron I would consider it but it's not. They were able to make really nice primes that are excellent optically and smaller than their rivals (50 1.4 II, 135 1.8) but haven't been able to do the same with their 2 zooms. Shame.

Might not be lighter, but it is quite a bit cheaper. For me, both lenses are way to heavy to lug around.

I will pass. Still waiting for 24-135mm f1.4-f1.2-f1.8.

I hope we get some high quality comparisons soon, where things like rendering or CA/fringing in reallife (I find it hard to believe SY is better corrected in that regard) is shown. One thing that would be easy to test, but of course is omitted in the videos above, is vignetting. Wide open Tamron has a lot of swirl in its bokeh, so I wonder if it's the same case for the new Samyang.

Samyang to me has almost always rendered (subjective I know) better looking images than Tamron. Tamron's version of this lens looks like they might have figured things out but certainly is not worth the price. I have ordered the Samyang so we will see how good it is. I expect it to be just as good if not better,

I actually really like Samyang, I think their lenses are best value by far and some even compete IQ-wise with the GMs.I've been using the Tamron for a long time now and I think it renders really nicely for a zoom and CA is also very well corrected. If SY can be even better with similar AF (Tamron is basically latest GM level, except for tracking, latest SY motors seem a step below in my experience with SY85 II) and 500+$ cheaper, all power to them

Beside comparisons the whole concept of both lenses still has some downsides imo.
- No ILIS. Beyond 85mm ILIS becomes important imo.
- The flexibility of the zoom range makes it a lens being 90% of the time on your camera, at least for me. The weight OTOH kind of defeats that benefit, as you would still want to change lenses to get rid of the weight. When going beyond around 800g I don't want to have a lens on my camera all the time.
- For background separation there is a kind of dip at 85mm. At 35mm f/2.0...Show more →

Some of what you say is factually true but I don't agree with your last point. To suggest that this lens is flawed has "only a stop difference" at 35mm or because it has a dip in subject separation at 85mm where it maxes out at f/2.8 seems unfair, given that it has a faster aperture than *every* competitor on the market (I.e. other standard zooms) at the 35-70mm range. Your interpretation also misses the premise of the Tamron (and Samyang for that matter): which is that it is a "bag of primes" that goes from a standard/wide angle FL to a moderate tele in ONE lens without any lens changes. This is hugely valuable in some circumstances - for me, it is absolutely perfect for shooting my two energetic kids in the park and I suspect it would also be equally good for dog owners. By the time I've switched lenses to a 50/1.4 or 85/1.4 or indeed 70-180 or 70-200 my subjects would have already moved away. I can only surmise that you shoot other kinds of subjects which wait for you to change lenses. Horses for courses..

I don't disagree with you that I'd rather it be lighter, but you can't have it both ways and say that it is both not fast enough and not light enough. For me the 35-150 completely eliminated the need for a telezoom for my kind of subjects (I.e. no wildlife) It is about the same weight as a 70-200/2.8 but way way way more versatile for the aforementioned reasons. The Tamron 70-180 is about 30% lighter but similarly lacks in versatility vs 35-150.

Back to the Samyang, the biggest problem for me is that the Tamron is tried and tested, and market prices (new and secondhand) in my view have dropped enough to make the Samyang a hard sell even if one assumes it is as good as the Tamron. "Copycat" lenses like the Sigma 24/1.4 DG DN potentially suffer a similar fate, that is the reality of first mover advantage.

This whole review feels like a Samyang ad. Samyang only sent this new lens to Tom and nobody else, even though there are much better lens reviewers, like Gerald Undone. This review would be a lot more credible if he didn’t try to crap on Tamron to make the case for Samyang. His images are also published on Samyang’s site so that tells you something. I own the Tamron and never seen any of the issues he mentioned in his review, especially the soft IQ issue.

My only experience with Samyang is with their cheap sub $300 compact primes and...Show more →

His comments about corner softness of the Tamron caused me to wonder about my 35-150mm. In the times I have used this lens, it has always yielded really sharp results. I setup my test chart, lights, tripod, A1, etc and compared to my GM 24-70mm f2.8 II and GM 70-200mm f2.8 II in the comparable FL's at f2.8. This is what I found:

The overall sharpness of the Tamron lens was really, really close to the Sony lenses at 100% on a 5K, 27" monitor.

Both Sony lenses have a fairly flat field. The Tamron exhibits some field-curvature, so that corners are softer when focus is in the image center.

When focus is near the corners, the Tamron is very sharp.

Since I have mostly used the Tamron lens for portraits, and my focus is always on the eyes, anywhere in the frame, this explains why my results have always been outstanding. If I shot brick walls at f2.8, things might be different. Of course, for general landscape photography, field-curvature is rarely a problem.

It is possible that the Samyang lens exhibits a flatter field.

Finally, as nice as this Tamron lens is, I rarely ever use it, mostly preferring primes. I'm thinking about selling it, which I generally do for rarely-used lenses.

I was wondering if any of you could shed any light on Samyang and their steppers? They claim they have "Linear STM" but I've seen some people on comments sections say they don't really have Linears in the sense that Tamron and Sony have but instead are just using marketing. Does anyone have any experience with Samyang on that front? I know the lens isn't out so I guess no one would really know about this particular lens. The youtube video seemed to indicate a very slight AF noise but it seemed very tolerable.

Btw I ask because I'm seriously debating buying this over the Tamron to save a bit on another piece of glass I want.(Sony 200-600mm)

I really did like his review and he was very straightforward in the comments that it was just what Tamron sent and he wasn't paid for it or anything. Was a very thorough review as well.

I doubt that any of this is him accidentally getting a bad copy of Tamron. Shortly after he released this video, he made a pretty cheesy YouTube Short mocking Tamron and praising Samyang. I think he saw a strong backlash from the community on his poor attempt to crap on Tamron and now he is backpedaling and trying to restore his reputation as a fair and neutral lens reviewer.

I am actually a subscriber of his channel and enjoy watching his reviews, but I don't think his videos are really that much useful in terms of evaluating technical qualities. He has three social media influencer type models that he uses in all his video and if you are into that sort of things, I guess you can say that his videos are "better" than Gerald Undone, Dustin Abbott and other nerdy Youtubers.

It’s not, Tom had a bad copy of the Tamron, redacted the portion and doing a follow up.

You have to keep in mind that Samyang is a Korean company, they have slightly different tactics for marketing. The 24-70 was hardly marketed as well, they may not want to pay the fees associated with big influence reviews. Most won’t do it free.

Their marketing is rudimentary based on insider knowledge.

Compared to many Chinese brands that have it down to a science. A lot of the latest lenses by samyang get minimal marketing.

Linear and stepper motors are mutually exclusive categories. Stepper motors move the elements in a circular motion around a central axis and were often used in clocks before they were used in cameras if that helps understand how they move. Linear motors as the name implies moves the elements back and forth in a straight line. So saying you have a linear stepper motor is an oxymoron--it is like saying you have a square circle. It is a claim that isn't possible.

That said the crazy idea often propagated on these forums that one time of motor (usually linear) is better than the other type of motor is equally silly. What matters is the details of how the motor works (e.g., how much power it has, how fast it works, how quiet it work, etc) not the type of motor. Sony has in recent years built some really great linear motors, but that doesn't mean stepper motors are necessarily worse motors. It is people who argue for such non-sense that leads to the ridiculous and obviously untrue marketing claims of linear stepper motors. What we need is better specification of the motors in our lenses regardless of what type they are.

It came in today. So far it's very nice but only weird thing is it has zoom creep. Guess it's not a deal breaker but kind of annoying that it does it. Wonder if there is a way to tighten it up.

I noticed that my Tamron 35-150 developed this creep - it easily extends to 150 mm when turned down. This might be recent though, after 2 years and 4 months of regular use.

Well that makes me feel a little bit better though since it's brand new it only has more creep to develop I suppose. I sent their support an email to ask if it's expected or not. The box it came in looks like it got hit pretty hard tbh.

I think there is a company out there that sells silicon bands to help with creep issues. I don't have this issue on my Tamron 35-150mm after 10 months of careful ownership. I am very interested in seeing images form this lens and see how it compares with the Tamron.

Whether or not the motors are actually at the point where the marketing hype meets reality is one question. However, from a mechanical standpoint there are three real advantages of linear (electromagnetic motors) over stepper motors.

Less moving parts means less points of failure which should mean higher average durability. No idea how things have progressed since this post, but in general we're already at or near the point where linear motors are mechanically simpler than stepper motors. At some point, failure of electromagnetic motors should approach the point of jamming/derailing of helicoids.

The simpler design allows for easier insertion of linear motors inside of other mechanisms. Again, this is covered by the blog post but even beyond that I wouldn't be surprised if linear motors was how things like the 16-35 pz ended up being so compact. I'm not an optical engineer so it's hard to say specifically what would be impossible using steppers, but in general the same expertise applied to simpler problems allows for better results.

While it's hard to say if acceleration/top speed will ever be an advantage due to that also relying on power delivery and power efficiency (and not just mechanical capability of the motor design), linear motors can absolutely be more precise than steppers due to the precision of stepper motors being mostly gear limited. This advantage will mostly manifest in applications like macro or wide aperture lenses where stepper motors traditionally took a speed hit for greater accuracy. Linear motors need no such sacrifices—compare focusing speeds of the 50 1.2 S, 50 1.2 RF, and 50 1.2 GM. Speedy macro lenses should also be possible here.

So yes, in many ways I'd say Linear motors are a technological leap.

There is no evidence whatsoever that linear motors are simpler than stepper motors. Stepper motors can be super simply and they were as built into clocks for decades. No evidence linear motors are a technological leap either. They have been built into speakers for decades.

There is zero evidence that linear motors are more precise either. Keep in mind stepper motors have kept time precisely for decades in clocks. They have been used for decades and after decades of use they still precisely keep time.

You are again parroting points about linear motors being better than stepper motors with zero evidence. Not a single link comparing the two technologies. There is a name for those sorts of claims: misinformation.
