Third-party lenses have been beneficial for many individuals who require a second lens. This can mean you get a lens that offers more flare or extra bokeh, or it can provide a good build quality. Third-party lenses are also more cost-effective, but that comes at a cost of weather sealing. However, if the latter doesn’t matter to you, then there are a few options in this list that can be of help to you today.
