Native or EF mount for B and W landscape lens

I’m going to be the new owner of an SL2 in a few days. 
 

For my landscape work… would I notice a difference in IQ  between mounting a canon 100-400 EF lens compared with the native sigma 100-400? 
 

I want the best IQ (sharpness, micro contrast) for my black and white landscape photography.

Which version of the Canon 100-400?  Definite IQ improvement in version II.   Sounds to me like you already have the Canon lens, just try it, and see if it satisfies.  

The Sigma lens is smaller, a lot lighter, and needs no adaptor, all big advantages.  

Having used both on the SL2, if we are talking purely landscape/still images with no need for AFC I think the Canon version II had the edge, but if you are considering which to purchase, then the Sigma would be my choice.

Others may disagree as is always the case😁.

Based on this criteria alone, for tele zooms, the SL 90-280 is tops.

But if price is a constraint, it’s easy to determine between the two mentioned options…

I used to own version II. Don’t own any lens right now… 

Just looking for pure IQ

I had the first version - hated it and ditched it as soon as I could. IQ not up to standard and when used in dusty conditions it was filled with dust within a few a hours. I think the second version was improved.

if IQ is so important I would look at Leica . 

Even better is not to use zooms.

The 90-290 is way out of budget, hence why I didn’t mention it. 
 

and please, where can I find a 400 Leica SL prime?

 

I use primes. This is my telephoto.

 

thanks

If the SL 90-280 is out of budget, then I doubt an eventual Leica SL 400mm prime will be any less expensive.  Your best bet for a prime lens would be to go for an R mount 400 lens and an R to L adapter.  Others have posted that the Canon 400mm DO lens is excellent, but that is expensive too.

Good luck!

Leica is rumoured to come out with a 100-400. Most likely based on the Sigma lens, but may have some extra tweaks. Might be the next best thing compared to the 90-280.

Depends on how much you trust rumours and how long you are willing to wait.

Interesting!

I know you said 400mm, but if you can live with 300mm, consider the 70-300 Panasonic L mount. It is lighter and more compact then the Sigma 100-400, which makes it easier to take with you. At 300, it is sharper than the sigma 150-600 that I compared it with, and for what it’s worth, internet wisdom suggests that the 150-600 is sharper than the 100-400 at 400. Bonus is the 0.5x close focusing capability. Negative is that it doesn’t come with a tripod collar, so you might want to use a remote release or 2 sec shutter delay. There does seem to be some copy variations, so make sure you get a good one, but that goes for all these lenses.
