Sigma v Tamron
Aug 23, 2013 03:56:29 #
At the moment I have a Sigma 18-200 lens(no stabilising feature) and will update it with Sigmas 18-250 (with stabiliser) or Tamron 18-270 lens. I have also been reviewing mirror lock up because some of my photos are out of focus. I would like to know if image stabilising feature has any effect on vibration caused by the mirror swinging up when a photograph is taken.I appreciate that using long end of lens in poor light will have limits and is partly why I am going for image stabilisation.Any help will be appreciated

I have 2 Tamron 18-270 lens', one my D-90 and one on D-7000. I rarely take them off because they are so versatile, I have been using them for several years and absolutely LOVE them. I have a Sigma 10-20 and 50-500 and when I switch to one of them is the only time the 18-270 comes off.

I have an 18-300 on my Nikon D200 and a 28-300 on my Nikon D3. I never use mirror lock on either, I rely on their stabilizers.
Mirror lock is handy when you're doing a very sensitive image at an incredibly slow speed in an environment where you can't support the camera rigidly. It does give the camera a chance to stop shaking. But if you have a sturdy tripod that usually prevents major shake anyway.
Far more important for me is the shutter speed. I find that if I'm shooting around 1/500th or faster there's no problem with shake and no need to lock the mirror. Generally the stabilizer is all I ever need to keep the images sharp even hand held.

If you are having what you think are focus problems you should review ALL your sharpness ( including shutter speed) techniques - including being on a monopod at 250-270 mm. Focus errors may also be caused by a faulty lens and/or camera relationship- but it is far more likely operator technique. And, yes OS/IS may indeed be of some help to you.

I agree. You do not say what type of photos you are taking or your camera which might help getting answers.
The use of a tripod or monopod could help as well as shutter speed. Increasing your ISO or f-stop might help also. Remember to NOT use OS/IS when using a tripod though.
As for the lens, I would lean towards Sigma over Tamron. They have made some large improvements in the last couple of years. I don't own either of these lenses so someone that does may be of more help here though.

Thanks all, I guess I will have to be more careful and hope the new lens with IM will help
