Tom,
I have a Canon 70D and am on the verge of buying the EF 100-400mm f/4.5-5.6L IS II USM and Canon EF 17-40mm f/4L USM lenses. I go to quite a few airshows annual so want the 100-400 zoom for aircraft shots. The one thing that is a pain is the weight and size of the damn thing.
I have never considered the Sony A6000 as an alternative but for size alone it does appeal and with what I'm going to spend on the Canon lenses i could pick up the Sony. Which lens would you recommend for the Sony as an equivalent for the 100-440 zoom?
Well I was in your situation and nearly pulled the trigger on the 100-400mm MKII because its the best zoom lens in its category, bar the 200-400mm. Its weather sealed, amazing build quality and Image quality. At £1600 its a niche product, and for me on a full frame camera 400mm isn't enough. The alternative is the Tamron 150-600mm its around £750 and to 400mm is very good, gets a little softer at 500mm but very usable and again at 600mm but the fact its there you can't go wrong and for the price… Your 70D has a 1.6x APSC crop sensor, so when you put a full frame lens on the camera like the 400mm you would get 640mm, the tammy will give you 960mm but from what I have read it plays better on full frame than crop.
For me since going full frame crop just doesn't do it for me anymore theres something about the look of the images and the quality of the images on full frame. But FF is a lot more difficult to use than crop, crop is a lot more forgiving.

I took my 70-300mm L across south america and north america, taking it to the amazon etc and it was just far too short on full frame and I ended up missing some pretty amazing things because I just didn't have enough reach, even with 100-400mm an extra 100mm won't make much difference so for wildlife in Africa I pulled the trigger on the 150-600mm Tammy yesterday as park cameras had a bank holiday sale with it for £750. It matches the 100-400mm to 400 and has an extra 200mm when needed. Only problem is its no where as well built and isn't weather sealed, which is a real pain as I my gear gets used very hard and I don't think its up to the task especially the dust and sand. In comparison my 70-300mm went through complete torrential rain of the amazon might as well have been submerged, the heat and dust of the atacama desert and the arctic storm temps of -30-40 in Chicago and Detroit in north america. It came home without even a slight bit of dust, incredibly well built and the 100-400mm is basically the same with an extra 100mm. At the price of the tammy if it only lasts the trip I won't loose too much sleep and should still be under warranty. The images are more important to me. I think its a really good option at the moment. You may not need 600mm for the air shows but its there… and air shows don't really put you in the same sort of extreme conditions except the UK rain.
But I agree with you it is heavy and the 150-600mm is heavier. Unfortunately in the mirrorless world there is nothing that covers it. The options would be the 18-200mm or the 55-200mm which won't offer anywhere near the quality of a 100-400mm, the 70-200mm F4 G lens will give similar quality, on the 1.5x crop A6000 would give you 300mm. With your 70D and 400mm you get 640mm so your getting just shy of half the range. It is also a similar size and weight to the canon 70-200mm F4 so this is where the advantage of mirrorless goes away. If you shoot fast subjects and need a telephoto lens then the DSLR camp is still where you need to be. The mirrorless cameras are too small to mount these big lenses on the lens mounts aren't as strong either so if you are putting a 1.5kg lens on a 400g body it will be hugely front heavy and getting a good grip on the body will be very hard and uncomfortable especially for a full day shooting an air show.
But like I said above if you want an overall camera which can shoot nearly everything mirrorless is a good place to head. But for these niche subjects like weddings, events, motorsport, wildlife or others like the airshow DSLRs are still king atm.
Also a little warning when buying grey market. I bought my Tammy from a UK distributor because they aren't renowned for being the best in terms of tolerances like I was saying above. With Canon lenses they are usually very very good in terms of autofocus adjust, the tammys tolerances are no where near as good, Ive seen lenses being up to + and -20 out which is a wild swing of AF performance which is unacceptable imo. So I want the option to be able to send it back and get another copy if needs be. Canon lenses are usually within -3 to +3 so that to me is acceptable. So I wanted to make sure I could send it back if I had issues, it might only be £750 which is cheap compared to the other gear I use but if its not right £750 is £750.
Buying from digital rev is great but if you do have a problem you will have to pay for it to be returned. The lens I bought with the shard of metal in the barrel I said I wanted a straight swap, it was going to cost me £250 to send it back to Hong Kong insured for the £1600 and they wouldn't pay for the return, it also needed to be examined so even then I wasn't guaranteed a replacement. In the end digital revs UK customer service sorted it to be sent through CPS (canon professional services) to be serviced and repaired and they paid for everything. I assume it had a bump in transport. It came back immaculate as with most items that are professionally serviced they have a much higher tolerance as each one is tested strictly to manufacturers tolerances. Came back amazing and the only lens I have that is 0 on the AF adjustment. But just a pre warning. Thats the only problem Ive ever had and spent thousands with them and saved thousands too.
