Is the Sigma 35mm ART lens worth buying?


The Sigma 35mm Art lens, like all lenses in the Sigma Art range, is an exceptionally good lens. This is a tough and durable lens that is exceptionally well made. The action of this lens is super smooth and not at all clunky. The image quality is superb and images are sharp, crisp and vivid. There’s no doubt that the Sigma 35mm Art lens is awesome but this does come at a cost, and a very high cost at that.

The image quality of the Sigma 35mm Art lens is awesome, but is this level of detail really needed? Put an image taken with the Sigma Art lens on a photo editing program and go pixel peeping and it will be flawless. Put an image taken with the Sigma Art lens under a microscope and it will be perfect. This is all great stuff, but in the real world no paying client is going to scrutinise a photo to this extent. Other photographers may critique an image by going pixel peeping, but you should ignore these OTT and overly critical photographers with nothing better to do than nit-pick over things you can barely see with the human eye. At the end of the day it is the paying customer who determines whether an image is good enough or not, and I can assure you that images captured with the Sigma 35mm Art lens are simply too detailed.

If you want the kudos of owning the best 35mm lens the Sigma 35mm Art lens is for you. If you want to impress your photography buddies or attempt to make them jealous the Sigma 35mm Art lens is for you. If you want to brag on the photography forums the Sigma 35mm Art lens is for you. The thing is, you are going to have to pay through the nose for this.

If you want a 35mm lens to capture photos that are more than good enough for commercial use and will keep the paying customers happy there are alternatives to the Sigma 35mm Art lens. These lenses may not be as bullet proof as the Sigma 35mm Art lens but they are tough and sturdy lenses that plenty tough enough. These lenses may not have the same minute levels of detail as the Sigma 35mm Art lens but the image quality is plenty good enough to impress paying customers. The alternative 35mm lenses will not only impress but also save you a whole heap of cash too.

Remember to consider the crop factor before buying a lens for your Canon Camera


If you shoot a Canon dslr camera with a crop sensor and want a lens with a 135mm focal length you do not want to go and buy a “135mm lens”. It may seem like I am spouting rubbish at the moment, but please bear with me on this and all will become crystal……..

A crop sensor camera doesn’t change the actual focal length of the lens you stick on the front of the camera but it does change the effective field of view. A crop sensor camera increases the effective focal length by 1.6 times, i.e. a 135mm lens effectively becomes a 216mm lens (being 135 x 1.6). This basically means the field of view of a 135mm lens on a crop sensor dslr camera is the same as the field of view of 216mm lens on a full frame camera.

An 85mm lens has an effective field of view as a 136mm lens on a crop sensor dslr camera, and whilst this is not the 135mm you’re after it is pretty damn close. Besides, you won’t get closer in the real world.

You may already be aware of the crop sensor effect, and if you are the above won’t be new to you. If you are not aware of the crop sensor effect you are not alone, from what I have discovered from reading around the various photography forums I actively participate in. It appears that many photographers don’t understand or appreciate the crop sensor effect and consequently end up buying an unsuitable lens. 

Before you part with your hard earned money and buy a lens make sure you consider the crop sensor effect and get a lens that is the “effective” focal length you need. 
If you want a lens with an effective focal  length of 35mm for your crop sensor dslr camera the only real option is a 24mm lens. Okay, this gives an effective focal length of 38.4mm, but you won’t get any closer.

​If you want a lens with an effective focal length of 85mm for your crop sensor dslr camera the only real option is a 50mm lens. Okay, this gives an effective focal length of 80mm, but you won’t get any closer.

​If you want a lens with an effective focal length of 35mm for your crop sensor dslr camera the only real option is an 85mm lens. Okay, this gives an effective focal length of 136mm, but you won’t get any closer.

Canon 50mm f1.8 or Yongnuo 50mm f1.8


If you shoot a Canon dslr camera and are looking for a 50mm f1.8 prime lenses there are two options, and these are the Canon 50mm f1.8 and the Yongnuo 50mm f1.8 lens. The Canon has been around for several years, and is a bit of a dinosaur whereas the Yongnuo has only been around for a few short years, and is relatively new.

I have read several negative reviews about the Yongnuo 50mm f1.8, and all of these comment on the poor build quality. Okay, the Yongnuo 50mm f1.8 lens isn’t the toughest lens out there, and it does feel like a child’s toy rather than a serious photography lens but so does the Canon 50mm f1.8 lens. Using the Canon 50mm f1.8 and the Yongnuo 50mm f1.8 and comparing them side by side clearly shows there is no difference in build quality between the two lenses whatsoever, and neither one is better than the other.

Many of the Yongnuo 50mm f1.8 reviews I have read comment on poor image quality. Okay, the image quality of the Yongnuo 50mm f1.8 may not be exceptional, but it is just as good as the Canon 50mm f1.8. I have done a side by side comparison of photos taken with the Yongnuo 50mm f1.8 and the Canon 50mm f1.8 and they are identical. Yep, there is no difference in image quality between the two lenses whatsoever.

The Yongnuo 50mm f1.8 lens and the Canon 50m f1.8 lens are identical in every way, other than the price - the Canon 50mm f1.8 is more than double the cost of the Yongnuo 50mm f1.8, so it is easy to see the Yongnuo 50mm f1.8 is awesome value for money.

If you are looking for a 50mm f1.8 lens for your Canon dslr camera I highly recommend the Yongnuo 50mm f1.8, and I assure you that it is identical to the Canon’s own 50mm f1.8 lens only you’ll have some money left in your pocket to spend on some other piece of photography equipment.
