Review on Sigma 18 300Mm F3 5 6 3 Contemporary Macro by Sean Young

Build quality is normal. The zoom can be tight when the lenses are new. Zoom lock is also useful to prevent zoom creep when you hit your chest with the camera. your own. However, autofocusing in low light can lead to premature shots. Zoom range aside, acceptable distortion is one of the reasons these lenses are good for everyone. With such a wide zoom range, distortion is well controlled over most of the focal length and is only noticeable at the beginning of 18-20mm. The sharpness of the lenses is ok. According to DXO, 7-8 megapixels is the maximum resolution they can offer and I think the same. This is more than enough for photography enthusiasts and for keeping photos as keepsakes. However, by sharpening +2 +3 in ViewNX or in the camera settings, you can match the sharpness of more expensive lenses when shooting only in JPEG. The OS doesn't seem revolutionary, although there aren't many blurry photos yet. CA does not bother. much, although my camera is permanently set to aperture priority with F8. It seems to be the cheapest option on the market compared to Nikkor 18-300mm, Tamron 16-300mm. After studying all the competitor lens reviews, I didn't notice any features that made me buy more expensive Tamron/Nikkor compared to Sigma, so Sigma was a win for me. The built-in flash should not be used at short focal lengths as this will create a shadow underneath, and I personally don't find these zoom lenses at all suitable for flash photography due to their high flare/ghosting tendency. Keep that in mind. The lens cap is awful, it's made out of rough plastic and actually scratches the filter ring from the inside. So if you know a good alternative, please let me know. Overall I would recommend them to anyone who has bought a DSLR and multiple lenses but films with a cellphone when traveling as changing lenses is a hassle and time consuming and the camera bag gets bigger. and heavier etc. You can safely sell whatever you have and always have those lenses on your camera.
