. . . As for the OP's post, its funny how Sigma updating the 120-300 so soon has been extrapolated to mean Sigma replace all their lenses on a regular basis.

of course Sigma is not making lots of lenses for the same purpose over time

These are the 70-200 AF lenses from the last 12 or 14 years out of my head

  • 70-200 F2.8 EX APO
  • 70-200 F2.8 EX DG
  • 70-200 F2.8 EX DG Macro HSM
  • 70-200 F2.8 EX DG Macro II HSM
  • 70-200 F2.8 EX DG OS HSM

To my best knowledge the first four a obsolete now

Compared with that the 120-300 is a conservative approach with only 3 versions in the last years

For me this looks like a pattern - bing out a new version every now and then to get customers attracted again.

In the same time frame Canon introduced

  • 70-200 f/2.8 L IS USM
  • 70-200 f/2.8 L IS USM II
  • 70-200 f/2.8 L USM
  • 70-200 f/4.0 L IS USM
  • 70-200 f/4.0 L USM

Thats over a 12 year period and in many cases the differences are extremely minor. Like the first two all that changed was the coating used on the glass, so hardly like the first one became obsolete overnight. Certainly with a 100-300 f4 I owned then that was the only real difference between the DG and non-DG version, and both sold for similar money second hand.

And that is another distinction, there is a massive difference between 'discontinued' and 'obsolete'. Would you consider the Canon 300 f2.8 L IS obsolete now there is a Mk II?

As for 'getting customers attracted', perhaps its just Sigma wanting to keep improving products in a very competitive marketplace.

yes I would regard the 300 f/2.8 (I) as obsolete - simply because Canon has officially announced that they stopped the official support of the lens and thus spare parts will not be produced any more.

This will lead to a shortage of spare parts sooner or later - if you happen to have one you better upgrade to the current one.

I am not familiar with the spare part situation at Sigma but I'd guess that for the earlier versions it is now hard to get a front lens or the AF motor . . .

The lenses till work and if they have been optically good why should anyone not use them.

But with modern lenses (all of them including Canon, Nikon and Sony) I am not so sure how long they will last with all the IS, VR and OS technology inside

But that#s a pure guessing - nobody has long term experiences of 10++ years - Zeiss and Leica lenses (being purely mechanical) seem to last almost forever - I am sure modern designs might be a bit more prone to fading
