Hi, Just after some advice on choosing the next lens for my Canon 700D. Currently the max I can spend would be around the £250 mark (currently a student on 3rd year of photography degree). I mostly do landscape and wildlife photography, but occasionally do macro. Have been looking at a few telephoto lenses; CANON EF-S 55-250 mm f/4-5.6 STM IS Telephoto Zoom Lens SIGMA 18-250 mm f/3.5-6.3 DC HSM OS Telephoto Zoom Lens with Macro SIGMA 18-200 mm f/3.5-6.3 DC Macro OS HSM C Telephoto Zoom Lens Any advice is appreciated on what you recommend. Thanks.
