100-400 zoom lens for Canon 600d

[Phil V]

The camera my son is going to buy is a Canon EOS R7, here's another question, would it make more sense to buy a lens compatible with this camera rather than one for the 600d and then use an adaptor?

If I were buying tomorrow, I’d buy RF glass for my RF cameras, but my EF lenses work perfectly with the adaptor.

That said, I wouldn’t advise others to only buy RF lenses, as I said the EF lenses all work fantastically, and people should buy whatever suits their needs. I might not advise buying really old 3rd party lenses, as there could be a firmware update in the future that cripples them, the mitigation for that simply being to not do all the updates (I don’t do them all)

Personally, I’m now down to only 2 EF lenses, the Tamron 17-35 wide angle that I could never justify replacing because I don’t use wide angle lenses often, and the 135 f2 which is my favourite lens, but also for the little use it gets, there’s no way I can justify buying the RF 135.

In fact as I’ve said prior, I used the original 70-200 2.8L on my R6, the R6 has IBIS, so not only was my 70-200 as good as it’d ever been on my EF cameras, it was actually better than it’d ever been.

But you need to bear in mind that RF lenses can’t be used on your 600d, whereas an EF lens can be used on both cameras

Canon EF glass works seamlessly on RF bodies with the adapter and can be bought cheaper than the newer, RF equivalents.

That said, it's probably better to use RF lenses on an RF body but if you already own Canon EF glass, the adapter is a no brainer, it's well worth the money.

I think I mentioned it earlier in the thread, I use the EF 100-400Lmkii on an R7, it's phenomenal.

Thank you, as you can see I know sod all , I'm still trawling through all the adverts for a lens, I'm not sure about the push/pull on the MKI lens, I'm used to the screw adjustment on the 55-250 so I dont know if I could get used to the former. I'll look at the prices for the MKII, they seem to be around £2-300 more than the MKI.

Thanks for the information, I'm wondering now whether to go for the MKII 100-400 as I am used to the screw adjustment on the 55-250, I'll keep looking for a change,I usually charge in like a bull in a China shop buying something I want ,I'm the fool who rushes in but for once I'm taking people's advice, I want the right one so I'll choose carefully.

Now there's a good point, thanks once again.

It’s not a straightforward decision, the Canon mk1 is quite cheap now, but it’s seriously behind the mk2, but the mk2 is around a grand. Right between them in terms of quality and price is the Sigma version.

Slightly cheaper than the Sigma 100-400 though is the Sigma 150-600, which bang for your buck is probably the best buy long lens out there, and I think it’s been mentioned before in this thread. Maybe too slow for winter afternoons, but it’s a cracking lens for the money.

I was wondering about that, I was taking photos of my Granddaughter's rugby match under floodlights last Friday and the club had the resident photographer taking photos,I asked him what lens he was using and he said a 150-600,his photos were much better than mine with the 55-250 so I have sort of been looking at them as well but not as much as the 100-400 . I really can't see to spending a thousand pounds on a lens ,in fact spending the £700ish I'm intending to will get me bound and tortured if my wife finds out. Not that I would mind being bound and tortured. OOer missis It's going to be 4-6 weeks before I make the final decision and actually buy one,I cover the most part of the 100-400 with the 55-250 so I'll take your advice and look for the longer lens. My son wants something to take on a safari they are going on next summer so the longer lens would be ideal. Thank you for your advice,I'll take it on board.

Honestly, I’d buy from a dealer or someone I know, but I have bought and sold on eBay in the past.

Thanks,I was just using this as an example,Ebay is alright for some things but,as you say I would rather buy from a reputable dealer where I am offered a guarantee.
