Is this the best superzoom lens you can buy?

Canon mentioned from the beginning that its new EOS RF mount would permit new developments in lens design and new prospects for lenses. We’ve been fairly impressed by all of the RF lenses we’ve seen to date, however that is the one which appears to bear out these claims.

What’s spectacular in regards to the RF 24-240mm f/4-6.three IS USM is the consistency of its efficiency throughout the entire zoom vary, and even at extensive lens apertures. You’ll be able to see the complete story in our Canon RF 24-240mm f/4-6.three IS USM evaluation.

The sharpness does fall off just a little in direction of the perimeters of the body, particularly on the longest zoom setting, however this can be a small level – this lens delivers each a sharpness (within the middle of the body) and a distinction at its most focal size that we’ve not seen earlier than even in the very best superzoom lenses.

Who wants a superzoom?

The concept of a superzoom may be very tempting. It’s a single lens that may do the job of a package lens and a telephoto lens mixed. No extra litter in your digital camera bag, no extra lens swapping, no extra pictures misplaced when you fiddle about with lens adjustments.

However superzooms have a draw back. With the intention to obtain a 10x zoom vary (or bigger), the designers have to simply accept some critical optical compromises – particularly if a lens like that is to be inexpensive. This implies the optical high quality suffers, with extra distortion and color fringing on the wide-angle finish of the zoom vary and – way more critical – a lack of sharpness, distinction and total optical high quality at longer zoom settings. 

What units the Canon RF 24-240mm f/4-6.three IS USM aside is that its photographs at 240mm are very practically as clear, sharp and contrasty as it’s at 24mm. It is a superzoom lens you possibly can really use in any respect of its focal lengths!

However is it dishonest?

The efficiency of the Canon RF 24-240mm f/4-6.three IS USM isn’t achieved purely via optical design. It depends closely on digital corrections. These may be utilized robotically in-camera or through lens profiles later in software program should you’re taking pictures uncooked recordsdata.

So with correction, this lens is optically wonderful with no vital color fringing, distortion or nook shading at any focal size – that’s fairly wonderful for any lens, not only a superzoom. However with out correction, the distortion at 24mm is so dangerous the corners of the picture are clipped. Clearly, this can be a lens by no means designed for use with out digital correction.

Purists gained’t be pleased. What we are saying, although, is that it’s the outcomes that rely, and if the Canon RF 24-240mm f/4-6.three IS USM can obtain a stage of picture high quality that may’t be achieved via optical means alone, then we’ll take that!

Superzoom lenses are sometimes put ahead as the right lenses for journey. We predict this one really is – and it is definitely an ideal (and nice worth) package lens for the EOS RP.
