You move in different circles. The 150-600mm C is a very popular lens with nature photographers, for example, the S less so, but the 60-600mm could become popular. The Sigma 100-400mm is a cheap alternative to the Canon version. And the major manufacturers have either introduced or will do so combining in-lens with in-body IS to give even more effective IS.true btu witrh sigma. their most popular lenses or popular lens in general arent telephotos unless you count the 135mm
I'd bet that the control ring is covered by a host of patents, Any 3rd party will need to navigate thru them, Canon has not sold licenses to lens technology so far, but its possible that they would swap licenses to patents if it was a benefit.Are you telling me I could’ve been using the nifty fifty over all these big expensive lenses all these years? Ugh Canon marketing!!!!!
if they’re just staying with original lens designs and slapping an adapter on these, I would think they could put control rings on the lenses.
They can’t move the lens any closer to the sensor than DSLR correct? Therefore leaving a 24mm or so extension on the RF lens?
DXO keeps the way they score products secret and no one has reverse engineered it. Possible its because its not totally related to lens performance, but to personal opinions. Certainly, their scores only apply to a certain lens / Camera model and can't be compared with a different camera. About all you can say is that a particular lens seems to work very well with a particular camera if tested in a warehouse.No, because DXO scores are highly dependent on the sensor. A higher resolution sensor will give higher score for the exact same lens.
Look at the Otus on a 5D IV and other than the Otus being sharper at f/1.4 than the Canon at f/1.2 the two are almost a perfect overlay. Then put the Otus on a 5DSR and watch it outrun itself on the D800E. You are just looking at megapixels and AA filters and not lenses. The RF lens softens a bit at f/1.2, but that is no surprise. It will score very well when Canon releases a high MP R body.I am not sure if I should trust DxOMark. But if their results indicate significant difference, I probably should give a consideration.
After Canon RF 50mm F1.2 comes out, praise all over the places. But check these:
Canon RF 50mm F1.2 scores pretty low at 38, ranks 174 in DxOMark ranking:
Canon RF 50mm f/1.2L vs Zeiss Otus 1.4/55 ZF.2:
Canon 28-70mm F2 scores even worse at 33, ranks 417 in DxOMark ranking:
Again... it depends. There is a lot more going on that what most people realize. Here is an example.That means Canon it’s own lenses will be superior than same-formula-multi-mount lens providers like Sigma, Zeiss, etc. if RF Mount really has advantage over, saying E mount.
We will see.
How certain are you about this assertion? I did look at DxO, and here's what I found:
Those are completely different lenses you're comparing though.How certain are you about this assertion? I did look at DxO, and here's what I found:
DXO scores make absolutely no difference as to whether or not the photographer can take a good photo. Screw DXO scores... no matter which manufacturer they favor.How certain are you about this assertion? I did look at DxO, and here's what I found:
IS lenses will not go on the back burner because of IBIS. IBIS can substitute for OIS to a certain extent, but it performs so much better in conjunction with OIS.Everyone company and i mean EVERYBODY has IBIS except canon , so IS in lenses can go on the backburner except for canon users to this date. SOny, Fuji, Olympus, Panasonic, and even Nikon have IBIS. Canon is just beating around the bush as usual waiting for us to buy all the cameras up before giving us more convenient tech. It's actually insane how they treat their customers when they have all that money
So you say, but DXO tells me that the nifty fifty is a better lens than the 600F4, so that’s the lens we should be using to take pictures of grizzly bears and lions..... what could possibly go wrong?DXO scores make absolutely no difference as to whether or not the photographer can take a good photo. Screw DXO scores... no matter which manufacturer they favor.
if that is true how many futures lens coming out have IS for all the mirrorless brands aside from telephotos. seems like much less incentive for it anymore and they can just focus on sharpness. It doesnt matter if you think it is a replacement for OIS. The companies are the ones that pay for it and will decide if it is a necessary expense.IS lenses will not go on the back burner because of IBIS. IBIS can substitute for OIS to a certain extent, but it performs so much better in conjunction with OIS.
I think you're confusing me with someone else as I never said anything like that; actually I don't think anyone has said anything like that. Someone just pointed out that DxO scores Nikon mount versions of a given lens, like the Sigma 35 1.4 as an example, higher than the Canon versions. Some examplesNo worries. Maybe you can add the link to the comparison you were asserting. You know, where the comparable Nikon lens is always better than the Canon lens.
