Zoom lens

I am thinking of changing my lenses. I currently use a 18-270 Tamron and a 150-500 Sigma. Would a 70-200L 2.8f + a 2x converter, or a 70-300L + a 1.4x converter give me a better quality image than the present set up? My camera is an 80D I also have a 50mm 1.8f and a 10-20 Sigma to cover wider angles. Main use for the Sigma is for airshows and cars.
Thanks in advance for any advise.

With zoom lenses, as with life generally, we don't get owt for nowt!

Professional zoom lenses tend to have a narrow zoom range because it's difficult to design a lens that has wide aperture, wide range and high performance at a sensible price. Movie zooms from the likes of Angenieux tend to be horrendously expensive!

The 70-200 f2.8 lens is one of the "holy trinity" so generally excellent and the production volume keeps the price down. Expect good performance when used with the current version of converter from the same maker.

Personally I would be looking at the mark 2 100 -400 paired with a 1.4 extender, the image quality of the bare lens will be better than the 70 - 200 and 2x combo....

Thanks for your replies, one thing I noticed about the bigma was the weight so this will have some influence on the decision. Next week I plan to go to Chester and get some hands on with different set ups Smile

Be aware the Canon 1.4x TC will not fit the Canon 70-300mm L due to the front nose extension of the TC fouling.
Like Phil, the Canon 100-400mm Mk2 + 1.4x TC gets my vote.

Thanks for the info on the 70-300

What William says "it's difficult to design a lens that has wide aperture, wide range and high performance at a sensible price" is very true.

Have you thought about prime lenses, this type ?

If you check the metadata of photographs taken with your zooms you might notice something that others have, that the vast majority are taken at one end of the zoom range i.e. fully zoomed in or out.

If you are serious about better image quality then go prime. If you have Lightroom it's easy to sort by lens then see the actual focal length you used.

I can recommend LCE in CHESTER.

Whilst I agree in many ways with Chris here, it is widely acknowledged that the image quality of the 100 - 400 mark 2 is better than the 400 f/5.6. The prime is an older design now and is minus IS, the only downside to the zoom is that, like most zooms, not the full 400mm but more like 380mm... (my 100 - 400 is actually sharper than the 500mm f/4 IS that I used to own)

Very educational discusion for me. My Bigma only gets occasional use and I hoped that a 70-300 with a 1.4 would be best as my 18-270 spends most of the time on my camera so buying a 400 or 100-400 would mean that I would still have to stick with my Tamron. Anyway I will try to get some hands on this week and compare the Tamron with the 70-200 and the Bigma with the 2x converter on the 70-200

But surely that would still be the case if you went for the 70 - 200?

Yes but instead of lugging the big lens around I pop on the 2x converter and sell the 150-500 Smile

I see where you are coming from, my choice would still be the Mk2 100 - 400, a 2x extender does have a hit on image quality, you will be at the same max aperture at 400mm with both, plus they are both about the same price... I happily hand held the 100 - 400 on a 1 series body for the whole day at an airshow. The main advantage of the 70 - 200 is the f/2.8 aperture throughout the 70 - 200mm range. I have tried the combination of MkIII 70 - 200 + MkIII 2x extender and prefer the 100 - 400, both the versatility and the image quality.

Of course everyones mileage will differ along with their reasons for preferring a certain set up, so at the end of the day it really is down to your own personal preferences and needs...

The prime I mentioned was just the first one I came across, it's quite a bit cheaper than the 100-400 zooms and these reviews aren't bad are they? There are better primes if you want to spend 2 grand instead of 1 grand.

This is what I want , can someone loan me some cash towards it please?

The 600 please

A 200mm 2.8L with a 2x converter. You’ll get one of Canons best ever lenses and still retain quality with the 2x attached.
