Its been 3 years since I got my first DSLR. I now own an T2I with an Tamrom 17-50mm F2.8 non-vc (thanks to the forum) and a 55-250mm. I also own an 975mm refractor APO triplet telescope that I use for Moon and planetary shoot. I could use the telescope for bird photography but its 19pounds and I have to carry a mount with 30lbs counterweight. not very practical.

I once own an 300mm F4L and I really miss that lens (like an idiot I sold it). I decided I need to go back to bird photography and get an longer range lens. I really don't like the 100-400mm push/pull design so It leaves me with little choice : Sigma 150-500mm. I understand a lot more about photography since I've been doing Astronomy photography so I think I can handle that big lens stepped down to F8 - F10 to get the result I need.


Canon 5D Mark III, Canon 70D, Canon EF 24-105L, Tamron 150-600mm, Tamron 70-200 F2.8 DI VC USD, Sony A7r, Sony FE 55mm F1.8

Sigma also makes a 120-400 that doesn't require the stop down that much.

Don't forget the Canon 400mm 5.6L for bird photography. Very fast, very sharp!

sounds like a good idea...and it'll be lightweight compared to your telescope :)

i use my 150-500OS as a push pull...it's so much easier in my opinion...

If it's for bird photography get the Canon 400 f/5.6 - I'm speaking as an owner of the Sigma 150-500 and the Canon.

They both seem soft to me.

the owl seems really over-processed in my opinion....there are plenty of bird shots in the sample archives to look at...i like the versatility of a zoom, myself and the OS as opposed to the 400L

And yes, they do look soft. I have a sigma 150-500 and also get soft image. I was thought it's because of my xs. I'll get a 7d soon to try the lens on

10 as best.Have the 3002.8 and 400 do canon but use the sigma more often.Waiting for the 600 f4 2 if it ever makes it to the market.
