[Music] Greetings everyone let's say you've just Splashed out a load of money on one of Canon's new aps-c mirrorless RF Mount Cameras like the r10 or the R7 but You're such a lord snooty level money Bags that you can't cope with whatever Zoomable little kit lens it came with Well perhaps Canon's popular zoomable L Lens could be the answer everyone loves An L lens the Canon RF 24 to 105 Millimeter F4 L lens has had a great Reputation on full frame cameras ever Since its EF Mount ancestors hit the Market in fact the latest RF Mount Version isn't that much sharper than the Original models how could it cope on an Aps-c camera especially one as demanding As the EOS R7 and how would it square up Against Canon's new RFS 18 to 150 Millimeter kit lens should you upgrade To that famous f4l lens or stick with What you've got we need to know and I've Taken a few few hours out of my busy Schedule to find out for you on the left You see the RF 24 205 millimeter f4l Lens and on the right the RFS 18 to 150 Millimeter kit lens there are lots of Similarities between the two lenses in Some ways both have excellent Electronics with great autofocus Motors And very steady image stabilization the First differences are totally obvious Despite having a far broader Zoom range
The RFS 18 to 150 millimeter lens is way Smaller that's because it's only Designed to cover a camera with a Smaller aps-c sized sensor whereas the 20 volt 105 millimeter lens is designed For full frame cameras and so needs to Be much bigger the 18 to 150 millimeter Is also way way lighter than the bigger L lens here's that Zoom range end Practice as you can see the 18 to 150 Millimeters tight at a far wider angle On the R7 camera than the 24 to 105 Millimeter does and also it zooms in Much much further so if you decide to Give the 24 to 105 millimeter lens a try On an aps-c camera you'll be sacrificing A lot of Zoom range and convenience here But another reason the 24 105 is bigger Is because it has a brighter aperture of F4 throughout its entire Zoom range Which you'll particularly notice when You're zoomed in here you can see the Difference at 105 millimeter the outer Focus backgrounds of the 24 to 105 Millimeter lens look much stronger than The 18 to 150 millimeter kit lens and The same focal length make it a better Lens for portrait and subject Photography as well as for shooting in Low light situations indoors or in the Dark and this is one of the key Advantages to moving over to using this L lens but admittedly it doesn't make a World of difference to your images some
App other advantages to the more Expensive L lens is that it's weather Sealed to help keep dust and moisture Out of it and it has slightly better Build quality as well as separate focus And control rings at the front it also Comes with its own lens Hood if that's Something of importance to you a Disadvantage of the yellow lens is that It's filtered thread size of 77 Millimeters is way bigger than the 55 Millimeter size of the smaller 18 to 150 Millimeter lens meaning your filters Will be way more expensive should you Choose to buy and use them overall in Terms of size and parameters not to Mention price if you decide to fix this Canon lens to your EOS R7 camera then Well you'll be making a major sacrifice To your portability and zoom range Although the maximum aperture you can Work with of f4 will at least be Brighter well perhaps there'll be a big Difference in image quality Canon's 24 To 105 millimeter f4l lenses have all Always been fully intended for their Bigger full frame cameras but they've Never been slouchers when I've tested Them on abs-c cameras either but then Again none of those aps-c cameras were 32.5 megapixels in high resolution the 24 to 105 millimeter L lenses on the Left the 18 to 150 millimeter lens on The right I'll be comparing these two
Lenses here at the same focal length if You want to see more image quality Results from the 18 to 150 millimeter Lens then check out my full review in The description down below or check out My full review of the lens too at 24 Millimeter both lenses from their Maxima Matches look fairly sharp in the middle Although interestingly the 18 to 150 Millimeter kit lens seems to have a Slight Edge in resolution in the image Corners the 18 to 150 millimeter lens Continues with that slight advantage That Advantage continues even though if You stop the lenses down to f8 and Testing well let's zoom in halfway to 60 Millimeter now in the middle of the Image the Canon lenses maximum aperture Of f4 means it starts without the 18 to 150 millimeter lens that'll come back in A minute in the middle it is again only Averagely sharp and over in the corners It's a little softer let's top down the Lens to F 5.6 and also at the same time Introduce the 18 to 150 millimeter lens The two lenses are performing about the Same here in the corners although back In the middle the 18 to 150 again Carries test a slight Advantage even Stop down to f8 the 18 to 150 millimeter Kit lens does seem just slightly Slightly sharper here finally let's Zoom All the way in well for the L lens Anyway to 105 millimeter at F4 again the
L lens is much brighter than the kit Lens so it gets her head start and Pleasingly its image quality is still Fairly good over in the corners though The image image is much softer let's Stop that L lens down to F 5.6 and now Introduce the 18 to 150 millimeter lens Whose maximum aperture is close at F 6.3 Both lenses are softer in the corners Although the L lens is now showing a Slight Advantage finally back in the Middle the lens is very very slightly Sharper again although the difference is Barely distinguishable stop down to f8 And the lens Advantage is still there But slight out than ever and over in the Corners neither lens looks especially Impressive so overall well the L land Was originally intended for full frame Cameras where it does perform Fantastically well on a 32.5 megapixel Crop sensor camera well that's just not One of its natural habitats and so it Doesn't really perform any better than The kit lens interestingly and you know What that's all you really need to know At this point in the video I could Probably take you through a few more Comparison but it's pretty conclusive Now that there's little point in Shelling out the dough for the 24 to 105 Millimeter f4l lens on a Canon EOS R7 Unless you're absolutely desperate for That maximum aperture of f4 above
Anything else compared to the 18 to 150 Millimeter kit lens the L lenses Zoom Range will be way smaller it'll be big Bulky and expensive and its image Quality realistically no better let me Be clear none of that is a criticism of The L lens no matter how it might sound Really it was simply designed for Full-frame cameras not aps-c and Certainly on a full frame camera it's a Shining optic Canon made it to offer Good resolution across a full-frame Sensor rather than optimal resolution Just in the middle whereas the RFS 18 to 150 millimeter kit lens was built from The ground up for aps-c cameras and That's all there is to it Canon's L Lenses are always amazing on full frame Cameras but on absc we well you have to Take them on a case-by-case basis Well there you go I hope you found that Interesting you know I have learned so Much about the performance differences Between full frame and apse cameras While testing lenses on this channel and Well it's still sometimes a mystery to Me you have to take these lenses on a Case-by-case basis all the time if you Found this video helpful then check out The rest on my YouTube channel Particularly if you like the Canon EOS R7 as I'll be featuring a lot of videos About it in the near future and how Canon's new RF mounts lenses perform on
