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.

  2. Sweet lens! I bet your were estatic when you bought the lens! Can’t wait to see your photo’s with it.
    btw, you should definitely switch off auto play in that video you have in your other post (people in general don’t like it when some music starts playing, just a though 🙂

      Starsquid, hey, thanks for visiting my blog again! ya, took me long time to think over it and finally not regret over the decision i made. For the price, you can get any better than this lens. Planning to shoot some photo this weekend, will post soon 🙂 Oh about the video, i tried, but wordpress doesnt not recognise the code that i posted, i have to take the video out and post as a link. Ya, first time using Live video and didnt realize it has a autoplay function – very annoying 🙂 I prefer youtube, but because the content has a music track, they will remove it if i posted in Youtube.
