Pros: Image quality, focus distance, aperture, stabilized.

Cons: Bad MF ring, absolutely bulky

Opinion: Finally a worthy all-rounder. Image quality that does not disappoint. Constant openness. Simply attached to the machine (fuji) and never detached again. Plasticky, rings like this, that of the MF looks like a broken toy, no buttons to disable the stabilizer or AF / MF, but the approach of this lens is anything but analog and you know. It arrived just when I decided to use (almost) only zoom and I will place it next to the 18-55 despite the overlapping of focal lengths. At 70mm F8 and medium distances it is absolutely identical and indistinguishable from the Fuji 55-230mm. At equivalent focal lengths it is higher than the 18-135 Fuji. Remarkable star effect on street lamps, it disturbs me a lot, but I don't know if it's a characteristic of the lens or the shooting conditions. I will make some comparisons. Update to 15/11/25: on the XT-100 it gives me problems focusing at a distance or infinity in not difficult conditions, sometimes it makes mistakes and blurs practically everything. I had put it up for sale for the size, but I changed my mind and it's attached to the machine again. Satisfying.

Pros: versatility from 18mm to 70mm at f2.8.Image quality and detail.

Cons: Maybe just the weight and bulk

Opinion: I have owned it for more than a year now as a replacement for the Sony E 18 135 equally good but which unfortunately not being constant f 2.8 had limits with low light. The quality of the color detail does not make me regret the Sony lens at all... indeed I find it decidedly superior! I am a landscape painter and consequently the focal range is perfectly suited to my purpose. It does not suffer from flare ... the only cons as mentioned before that compared to the lens owned this is definitely heavier but you can't have everything... obviously

Pros: Versatility, focal range, good quality, powerful AF

Cons: VC stabilizer that works well but to date conflicts on Fujifilm with cameras that have internal stabilization

Opinion: I bought this lens as an all-rounder in case one of my lenses should break or go to service, at 17mm and at 70mm at f/2.8 I don't say it's unusable but the photos are decent, at f/4 it improves the whole situation a bit on any focal length. I wrote to Tamron to report a problem with the VC, in practice on Fujifilm cameras equipped with internal stabilization the VC of the lens conflicts, in practice the photos are blurred paradoxically, disabling the stabilization of the camera (that of the lens you can't) the situation improves and the VC of the lens behaves very well I would say. I hope Tamron resolves by signing this conflict.

Pros: Focal range, brightness, minimum MF distance, stabilization.

Cons: Not very compact, vacuum cleaner.

Opinion: Certainly the most versatile lens I own at the limit of macro. Very good image rendering except for some compromises. Stabilization, etc. certainly a lens to buy. But be prepared to have dust behind the front lenses. Actually, I didn't know if it was a problem of my specimen but I read online that it is not an unknown problem. So consider that. Of course, if you keep it in a dry environment there are not so many contraindications but with a view to resaleability meh...

Pros: focal range, very bright, tropicalization, good colors, ...

Cons: at extreme focal lengths it is not accurate, distortion and vignetting at 17mm and softness and sharpness at 70mm

Opinion: A lens that I am very happy about, it is an all-rounder that fills my focal length needs, even with very good results. It is bright enough to be able to shoot even in less than perfect conditions, it has tropicalization, an excellent color rendering. for the most punctilious it is better not to shoot at the minimum focal length and at the maximum, but nothing shocking. Used for over a year with satisfactory results, I am really happy about it. A very useful and high-level all-rounder. Highly recommended.
