TOPIC: Sigma 28-70 2.8D EX

Sigma 28-70 2.8D EX 4 years 1 month ago #2354

Hi there,

I have recently dropped and broken my 18-105 kit lens on my Nikon D90. I am looking to upgrade to a 2.8.

I have a 50 1.4 and sigma 70-200 2.8.

I have come across a used Sigma 28-70 2.8D EX for £99 ($160). Does anyone have experience or thoughts on using this lens on a crop sensor?

I'm thinking of getting this lens and maybe a wide angle zoom also to make up for what's lacking in my kit!

Any thoughts would be much appreciated!

Hi there Ryan,

At firts, welcome to the forums! :)

I do not have expirience with that particular lens, but it sounds nice. For that price, you will not get a 1st class professional lens, but you can take the shots like you want them and correct them in your post processing.

I would say do it, go for your REDACTED :)

Greetings,
Roy

Does the D90 have a focus motor built in? D lenses need one in the body as they don't have af in the lens. Seems too cheap.

Yes Greg, the D90 has a focus motor. ;)

I'd go for the Sigma or Tamron 17-50mm f/2.8 if I was you and if you can afford it. 28mm is very long for the widest setting and on the D90, it is 42mm which is getting into short tele-photo category. I think even with a wide-angle, you will find this to be an inconvenience, having to switch lenses often. 17-50mm is equivalent to 25-75mm in full frame terms. Hope this helped. :)
