300 F2.8 & 2X teleconverter or 600

If you cant afford the 600 how does the 300 with TC compare i know it will be slower but how much worse will image quality be???

Thanks

it won't be awful, but you will really need good light. A big bright viewfinder from a 1 series or 5d would really help too.

AF rather than IQ tends to be the biggest challenge

the 300 2.8 with the 2x gives good results, actually quite great results. but shots from the 600 F4 are stunning.

I guess it depends on what camera body you use and the type of work you do. The 300 2.8 is a stellar lens that works well with the TC's.

If you are using any camera body other than the 1 Series, you will not be able to use autofocus with the 2 X Teleconverter.

If Wildlife and Bird work is one your agenda, I'd go with the 600 mm. I have the 600 f4 and really want the 300 2.8 as my second Super Telephoto.

completely false. the 300 2.8 will autofocus with the 2x on any DSLR because it is only 5.6 with the 2x on. on the 1series it can still autofocus with both TCs stacked

yeah but i just might be able to afford the 300 f2.8 but the 600 f4 will never be mine... cory why would AF be the biggest problem my 400 f5.6 focuses just fine at 5.6 wouldnt the 2.8 and a 2X TC be essentially f5.6?? and if im right the IS will still work with the TC??

Brandon

Yes, the IS will still work even with TC's. But, you know the rule is to not buy a lens when you are planning on only using it with TC's. Do you need a 300/2.8 for other things?

unless you NEED a 300 2.8 for something in that case i would suggest you go for the 500 F4. much better for birds and nature than the 300 2.8, and much more bugetarily feasible than the 600 F4

the TC's and AF aren't best friends. the 1.4x if it is enough reach solves a lot more problems than the 2x creates.

Well i guesse i would only be using it with the TC unless i can get really close to the bird the 500 would be better...then with a 1.4 TC i would have a 700 f5.6 lense with IS but the 500 would probably be fine in most situations(better start saving and lifting weights )... does the 1.4 give better image quality then the 2X??

Thanks

I just looked at the prices and i think it would be better to go with the 300 f2.8 the 500 is 2500 more when all is done with taxes... so i guesse i will have to think about this one...

Brandon

What is the longest lens you have now?

the 1.4x is considerably better than the 2, Q wise. there is little to no difference on the 300 with teh 1.4, but it will definetly be noticeable, though not unuseable with the 2x

I don't have the 600, but I have the 300/2.8 & 400/2.8. Both are stunning lenses, and I would expect stunning results also from the 500/4 and 600/4. I know that the 300/2.8 works very well with the 2X teleconverter, as does the 400. But, there is a bit of a loss in IQ with the 2X. I would say that the 300 + 2X is very good, while the 600 is excellent.

my longest is the 400 f5.6 but is only good in sunny days or with monopod...but it is still as slow as my 75-300...now im thinking i dont need longer and the 300 would be good for low light and it has IS and can be a 420 mm with the 1.4 TC F4...now im thinking to go with the 300 it is less money and more versatile in my opinion... what do you guys think??

Thanks
