    Not the sharpest lens in the shed, but very handy4.0/5

    Not the sharpest lens in the shed, but very handy Sometimes you don’t need a G-Master lens, but you need a lot more than a cellphone camera. The 24-240 may not be the sharpest lens that I own, but it certainly stands up to photos intended for email or any reasonable enlargement. Importantly, it is not too heavy, it is on my camera when I need it, and I don’t have to juggle lenses when I just want to be out on a nature walk with friends. They’ll be using their cellphone cameras, but my pix will be the wow! ones that everyone wants a copy of.

    Meh3.0/5

    Meh I bought this lens for the advantage of having a wide range of focal lengths in a one lens walk around setup for a variety of photography needs. While physically it fills that need, it doesn't live up to the quality of image I was hoping for. Images are soft, its slow to focus, and seems to hunt for focus quite a bit before settling in. Ive tried different focus settings on the camera (Sony A7R) and some work better than others, thought I still shoot a bunch of images to make sure that I get at least a couple that are usable, I would say most of the time 30-40% aren't very sharp. The image stabilization in the lens did help in smoothing out hand held video, however I would still use a tripod to get the steadiest shots. I think for the price this lens is a bit of a failure, I would place it more in the $300-400 range, and Ive got cheaper lenses than that, that have taken as good or better photos than this lens.Read full review

    The perfect walk-around lens for hobby photographer or entry-level professional4.0/5

    The perfect walk-around lens for hobby photographer or entry-level professional This lens is basically exactly what I expected: with such a wide zoom range, it offers a diverse range of uses, and is the perfect walk-around lens. However, you do sacrifice sharpness and low-light performance, and overall the images it captures are underwhelming. It's definitely not my go-to for professional photoshoots, but it certainly fills in the gaps when my 35mm is not wide enough and my 50mm doesn't quite reach. The specific lens that I purchased had some body damage, including a massive scuff on one side and scratches on the glass itself. However, all of this was in the descritpion and in no way affected the performance. Overall, I'm happy with this lens and until I can afford the prime lenses that cover this range, I'm glad to have this one in my toolbelt.
