Canon Fixed Focal Length EF 24 mm f/1 – A top quality piece of glass.

Please don’t take the amazon star rating too serious – every lens has its pros and cons that i wouldn’t want to squeeze into a single one-dimensional figure. A quick note about me: i have been into slr cameras and lenses for more than 20 years – as a hobby in the beginning and professionally later. Maybe because of my technical background i started testing my own lenses quite a while ago. I have a (no longer so) little test lab of my own where i do 6 different image quality tests (after taking a lens out for a while). 8 is usm is a compact and well-built prime lens with a nice wide-angle focal length, a good maximum aperture and a modern image stabilizer that compensates up to 4 f-stops. While the image stabilizer sounds great one has to consider that it’s not as necessary in wide-angle lenses as it is in telephoto lenses – but i still appreciate it. The lens is best used indoors or for architecture and landscape photography. When using the lens with an aps-c camera the resulting effective focal length of 38mm is somewhere in between a wide-angle and a standard / normal lens and thus can be used for a whole variety of things. The lens offers good image quality – sharpness is great straight from f/2. 8 and there is only a small amount of barrel distortion visible. My lab tests have shown that color fringes (‘chromatic aberrations’) both in focused parts (‘transverse ca’) of the image and in out-of-focus areas (‘axial ca’) are visible but compared with its immediate peers the lens’s performance is quite respectable. There is no curvature of the focal plane (‘field curvature’) but corner shadows (‘vignetting’) are very intense and they are visible even stopped-down. 8 is usm is much more affordable than the ef 24mm f/1.
Could be sharper for a prime lens, i have it on a 5d mark3. The gopro 3+ gives it a run for the money.
I spent alot of time researching into this lens, i note that most comments made in various forums about focus issues were around 2010-2012, taking into account the lens was launched in 2008, i guess canon have made some changes to the lens to rectify issues?. (not 100% sure about that) if your copy is not brand new, might be worth checking the date stamp. I purchased my copy brand new two months ago, thankfully no issues, focuses super quick,. 4 are creamy smooth, very sharp between f/2. 0i currently use this lens as a general/walk around lens on a crop sensor camera (600d), im sure it will work great on a full frame camera too. I also find that pictures taken with this lens hardly require any editing in photoshop/lightroom as the colours and contrast etc is almost perfect.Sometimes they just need minor adjustments. If you want to look at other peoples work produced with this lens, best place is: [.
One of the best of the non l canon primes. Great for the ‘almost’ wide shot on full frame and portraits.
This is quite frankly the most remarkable piece of glass i own. The lens its self is made of an alloy-so its reassuringly heavyi presume this would be billet aluminium,this reassured me of the build quality,especially after my last purchase which was the 100mm f2. 8l macro-which was disappointingly plastic(apparently some engineering grade plastic however i must point out that this lens is optically superb),no matter how you think about it,you feel cheated after buying one of canons ‘l’s. The build quality is fantastic,and this l is weather and dust sealed with no external moving parts,or extending barrels. I screwed a 77mm hoya hd uv filter straight on the front of mine. This lens is capable to taking breathtaking images-with almost a 3d effect. For such a big aperture lens,this is very very sharp. Some say in reviews the edges are softer at lower apertures,at 1,4 shooting resolution charts in a studio this may be the case,but in real life this is not so trueand if you like taking images that look like they are trying to crawl up out the paper,this wont bother you at all.Even reviews that have picked this up agree that by 2.

Works a charm with a7s + adaptor!

Quarter the weight and price of the L alternative

Canon Fixed Focal Length EF 24mm f/1.4L II USM Lens

I bought this lens to give me a small, lightweight, stowable wide-angle when going out with just the 70-200 on the camera, and to have a wide-angle prime in my kit. And to have an indoors, flash-free wide-angle option. It meets all 3 goals very well. I’ve done decent hand-held shots at 0.
It works perfect on my 5d2 body. The image quality is much better than 16-35 f2.
In common with its 35mm f2 image stabilised sibling, this lens is a perfect match and balance for the canon 5d mark iii, in terms of weight, shape and size. It also makes full use of the sensor’s capabilities, in producing very good all round sharpness across the frame at f5. 6 or thereabouts and with typically vibrant canon colour and good contrast at all apertures. Lens profiles abound for the post processing adjustments of images taken with this model, including visible vignetting on raw files. This particular adjustment is absolutely necessary unless you are deliberately seeking to darken your edges and a fair amount of the middle of the frame too. You don’t necessarily need to resort to canon’s branded ‘digital lens optimizer’ to squeeze the best performance out of the lens, but this is a useful option to have and many canon subscribers don’t even know it’s there for them. Chromatic aberrations are not a big factor and distortion isn’t much to worry about either. Distant horizons on seascapes appear pretty flat even without any form of post processing adjustments and if you choose to apply all the available tools from lightroom, dxo optics pro or digital photo professional etc. , the edges of the frame are not tarnished as a consequence. Focus on this lens is so quiet and fast that i often think nothing has actually happened when i half-press the shutter button.
I was forced to buy it because this is the only one lens i can use with dji zenmuse z15-5d.
In typical style of canon they produce a top class lens, which feels solid and gives good reliable performance. I was debating between this and the cheaper none l series and was really glad i made the choice. I am using this lens for astro photography primarily and am pleased with it’s response and speed.

A High Quality, Fast-aperture Wide-angle Prime LensPopular with photojournalists shooting close to their subject, the EF 24mm f/1.4L II USM is ideal for photographers who demand the highest levels of performance. |
Fast Aperture Prime LensThis lens has a large maximum aperture of f/1.4, making hand-held shooting possible in low light. Such large apertures can be used to restrict depth of field, even at such short focal lengths. |
Ultrasonic FocusingA ring-type ultrasonic motor drives autofocus very quickly and in near silence. Better holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode. |
Undistorted ImagesFor enhanced visual performance, the lens incorporates two types of special elements: aspherical elements to correct spherical aberrations and Super UD (Ultra-low Dispersion) elements to eliminate secondary chromatic aberrations. The result is crisp, high contrast and undistorted image quality all the way across the frame. |

Great stabiliser and no vignetting when using it with my a7s and a metabones iii. Colours are nice and a good filmic bokeh when shooting closeups, which you’d expect from a canon lens.
I bought this lens primarily because of its light weight and focal length that is ideal for landscape photography. It is a mite on the expensive side, but the results have impressed me and i have been very pleased with the purchase. Compared with a zoom lens, it converts the camera into something that is much more portable and easy to walk around with such as on a walking trip, or on holiday.
8 is launched in 2012 is an excellent light lens with great optics. The colours are vibrant, the image stabilization allows crazy low shutter speeds, and images are sharp from f/2. Build quality is great, with silent fast focus and a solid metal mount for those who change lenses often. The only shortcomings compared to the much more expensive 24/1. 4l ii are the lack of weather sealing, fast aperture and red ring. Only if you need the shallow focus of f/1. 4, weather sealing, or to maintain fast shutter speeds for action in poor light should you consider spending more.
I can always find what i’m looking for on amazon at a better price :-).
I have held off writing a review on this lens for almost a year. I really wanted to see how it performed on a range of shoots in a variety of lighting conditions. With images taken on a canon 50d and eos 1d mk iv. My conclusion is this is truly a wonderful lens. Handling of flare is particularly good especially when stopped down, chromatics are again extremely good, possibly better than any other canon l series i have tried or own, shots of fine tree branches against a blue sky show very little of that all to familiar halo effect. Edge distortion is handled so well its hard to see any except when displaying very large images. The evenness of light and colour capture are excellent. When using the lens hood there was no visible vignetting or edge darkening. Build quality is up to l series standard and can take assignment knocks and bumps with ease. It also seems to be good at keeping out the rain.
I bought this lens mainly because i work in tight areas. 8 without any iq/pq problem. I’m not pixel junkie, i rather care about the image itself. This lens offers beautiful images – sharpness, contrast, bokeh, etc. It offers even considerable depth of field as wide if you have a proper object-background positioning – which i like. As any such wide lens, it has perspective distortions. But this is not bad (at all).
24mm f/1.4 prime lens for use with all EOS EF lens mount cameras

Please note: amazon has lumped together the reviews of the f1. I was torn between this lens and the more expensive 35mm f1. In the end i went for the 24mm partly because it gives me a properly wide and fast option to add to my other fast primes and partly because it’s a very versatile focal length on a crop sensor equivalent to (24mm x 1. 6) 38mm, which is pretty much ideal if you’re just going to carry one prime lens to cover all bases. I use this lens on both full frame and crop sensor canons. The image quality is exactly what you’d expect from a canon l series prime lens – can’t fault it, though i’m not really into pixel-peeping. The size and weight are also a pleasant change – being quite modest for l glass. If i’m shooting indoor events after dark and only want to take 2 lenses with me, this lens plus my 85mm f1. 2l for tight shots make a great combination.
