Finally? Yes, it was a difficult decision, took me many many sleepless night trying to decide which is the suitable lens for my next investment. Finally, i had chosen to go with this lens and here are the reasons why:
- at 17-50, (27-80 full frame), i get closer to my subject and also allow me to include the interaction between the subject and the entities surround it. This is very crucial during a wedding actual day.
- although 18-200 is available to a DX camera, those affordable are not fast lens. In a low light situation, i prefer to shoot the scene using a fast lens with some fill-in flash and not using the flash to light up the scene.
- this lens are sharper & more accurate than Sigma 18-50mm f2.8 and has less known issues. Reviews claimed Tamron focusing speed are much better than Sigma 18-50mm.
- why not the latest version with VR/VC? well… I wont pay extra RM400~RM500 for the latest one. Addtional to that, reviews claimed the latest lens with VR/VC has some back-focus issue and also due to VR/VC features, the focus is slightly slower.
- with the aperture open at constant f2.8, i can shoot a scene at higher shutter speed thus allow me to capture and freeze the action. At lower f stop, such as 15s and below, the image will appear to be blur.
so what will happen to my Nikkor 35mm f1.8? This is still a great lens and i will still rely on it to take some great portraiture. The ability to stop down to f1.8 means having the option to have extra 3 or 4 stops from f2.8 could proof valuable in time. The 35mm produces a much better/ smoother bokeh when compare to Tamron 17-50.
Last but not least, many of my shots was produced using this 35mm lens.
