    smooth lens and great features5.0/5

    smooth lens and great features This lens is now my new favorite. If you're used to a smaller/non-bulky lens, it can be a little intimidating to get used to using but once you do, you will not be disappointed. It's easy to switch out with other lenses. The focus is sharp and the zoom is great. It's smooth in adjusting and gives a lot of options on what kind of image you're going for. The only downside for me so far, is with the autofocus (if not using manual), it can take what feels like forever before it actually focuses. It focuses for a split second and then slowly.......... adjusts and refocuses once again. I feel like it takes a minute but id said in the range of up to 30 sec depending on the lighting and whatnot. I'm not an aficionado in photography, still learning, so pardon if this doesn't help a lot of people, but just from an extreme novice's point of view, I do love this lens and the variety of options it gives me for taking photos at the price I got it for. I think it is well, well worth the sacrifice. You shouldn't regret it.Read full review

    floppy Canon lens3.0/5

    floppy Canon lens Received item in a few days. It looks good and it works. My only complaint is the barrel of the lens is floppy, it rattles when you carry the camera. It also moves when you happen to bump it with you hand. I'm a little disappointed that the barrel of the lens is so loose. I'll have to replace it with a different lens later.

    An Upgrade5.0/5

    An Upgrade I am enjoying the crisp images and the saturated colors that this lens produce. This lens takes me to a different level. The downside of this lens, as with other heavy telephoto lens, is the lens ring drift. When the camera is held with the lens facing down, the lens ring does not hold the lens in place, but it extends. Not a deal breaker, but something to note, and even consider before buying. Ask the seller. This is a high quality lens that represents a good value.
