Used analogs include the Canon 18-135 STM and the 24-105 f4 L. The same FR is being used here. I tested it against an alternate staffer CANON 24-105 f4 L in sunny weather, but with clouds, then in drizzling rain, and then inside an apartment with and without a flash at aperture 5.6, which turned out to be the most optimal setting for both lenses. The following are the deductions I made: For my own purposes, I find that hue 24-105 is a touch cozier, more vivacious, and more fascinating. This one appeared to have a bit more contrast, seemingly as a result of the less evident warmth. The center of the photograph has the same level of sharpness throughout. The two lenses in the camera were brought into proper alignment. I chose to bring it along as a second staffer in addition to the 24-105 f4 L because I wanted a wide angle lens that was also renowned for its sharpness, picture quality, and aperture. It was only possible as a result of the wide angle and aperture ratio of one stop that it turned out this way. All of this is in contrast to the 24-105 f4 L, whose focal lengths are more suited to my shooting style. The difference is readily apparent when compared to the EF-S 18-135 STM that I previously owned or the whale 18-55 that I currently have. Because of this, it is a fantastic crop staff member for you if these particular FRs fit your playstyle. Yet, it is abundantly clear that the price is excessively expensive, allegedly as a result of the absence of a suitable alternative; it is, after all, the best EF-S lens. It won't work to sell something that's virtually brand new, even if it's in wonderful condition, if you don't cut the price by a third. Just being pricey led to a reduction in the ranking. HURRAH. Sold for a loss that was just 15% of the original buying price. I have resolved never to shop again. It does not provide excellent quality, but the price is comparable to gold plating.
