Although it seems this lens carries a bit of a premium price, the performance it delivers probably makes it worth it, for those who require it. Sharpness is very good from maximum aperture, and can even be considered as outstanding as the lens is stopped down. Other optical anomalies, such as CAs, falloff and distortion are also kept well in check, plus the lightweight and compact dimensions of the lens should make this an ideal addition to any serious NEX camera owners kit bag.
It is yet another cracking lens from Samyang, offering fantastic performance at a very reasonable price. There really is little to fault with this design and will be a tempting proposition for many mirrorless users. This lens offers premium features, such as weather sealing, silent autofocus and Vibration Compensation, which will make it an interesting alternative to other similar lenses. It is certainly capable of delivering excellent quality images, with high sharpness in the centre of the frame.
Whether those extra features are worth the extra expense to you will depend largely on how you use the lens. For example, travellers may find the Vibration Compensation and weather sealing invaluable to them.
For the price, it offers outstanding quality, handles well and the build quality is excellent. When shooting into the light, the simple optical design ensures this lens maintain good contrast and is resistant to flare in all but the most extreme of conditions. Falloff can be quite pronounced as too can be barrel distortion but this is easily fixed in image editing software and you might like the fact that the corners of the frame are 2.
Out of focus areas are rendered smoothly thanks to the rounded aperture blades and the compact size and lightweight makes this lens an ideal travel companion.
Overall, it's optically superb, offers outstanding quality and is available for a really great price. It is a very fine lens in its own right, with excellent sharpness that borders on outstanding, low CA, no flare and a very pleasing bokeh. Add to that the low light potential and we have a very attractive proposition indeed. It's built well, handles well and produces stunningly sharp images from maximum aperture. Given the performance this lens delivers, the price is a small ask.
Even those not specifically looking for a macro optic will be pleased with how this lens performs. With this lenses ability to deliver extremely sharp images, it should win many fans amongst users of this camera system. The build and handling are about right for the price. Add in this optic's ability to take images you could almost cut yourself on, and you have a winner here. The wider aperture also means more difficulty in focusing, but only because the point of focus is so fine. In reality, if used carefully with magnifying aids then it is highly accurate.
However, the price is reasonable and the standard is very high, so there are clear benefits for those for whom the difference is significant. In any event, the performance is exemplary. Performance throughout the aperture range is very good to outstanding and even if focusing speed is a little slow, it's still well worth considering. The lens is built well and its lightweight design make it a great lens for holidays or a city shoot. Chromatic aberrations are kept to low enough levels that they shouldn't pose any issues and the slight amount of barrel distortion is quite common for wide-aperture lenses like this one.
Bokeh is pleasing and the lens captures portraits beautifully. Sharpness at the centre is simply excellent at all apertures and CA Chromatic Aberration is highly corrected at the centre, approaching zero. The coatings are effective and even without a provided lens hood, the front element is recessed enough to avoid any signs of flare.
Despite only having 7 diaphragm blades, the bokeh is still very pleasing. It is not as ultra-smooth perhaps as lenses specifically designed with bokeh in mind, but it is very satisfactory. With excellent sharpness throughout, low CA, low distortion and excellent manufacturing quality, it's a 50mm lens you can't really ignore. Sharpness can simply be described as excellent and CA is very well controlled.
There is Size-wise, it's a little on the bulky side but this is a small price to pay for an optic that can deliver such beautiful results. The standard 50mm lens, long neglected, has more recently seen a resurgence in popularity.
It is easy to see why - relatively low cost, fast, bright maximum apertures, fast focusing, the lens that can be taken anywhere no matter how low the lighting and the one that delivers the goods.
To many zoom orientated photographers the fast 50mm can be something of a revelation. Much of the performance of this lens is exemplary, especially considering the modest cost. The only real drawback is the susceptibility to flare, which is very evident in shots taken into the light. If this can be accepted then the lens is, without doubt, an excellent proposition. Sharpness levels in the centre are extremely high from maximum aperture, it's well built and focuses fast.
Images captured by the lens are bright, contrasty and have plenty of punch, plus there is an almost total resistance to flare, even with the sun just on the edge of the image area.
The colour balance of all Pentax lenses is excellent and this one is no exception with it producing colours that can be described as slightly warm but very much natural. Distortion is respectable and CA is controlled well. The conclusion is that this lens can compete with the latest high-quality full-frame lenses as an equal. It's also robust, well-made and all-in-all, is an unobtrusive addition to any camera kit.
As for performance, this optic proved itself capable of producing fantastic sharpness, especially in the centre of the image.
Those after a technically perfect lens may be slightly disappointed with the performance towards the edges, but for portraiture at wide apertures, the high levels of centre sharpness should produce great results. When shooting wide open images are reasonably sharp across the frame and CA levels are low enough to not cause concern. Barrel distortion is often present on wide-aperture prime lenses like this and even though it is slightly present, again, it's not really much to worry about and can be corrected in image editing software.
The sharpness in the centre is this lens' strong point, so if you tend to shoot at wide apertures this could be the lens for you. Micro Four Thirds camera owners after the classic field of view offered by a standard lens will not be disappointed by the optical performance of this lens.
It is a very sharp, contrasty optic, worthy of the Leica branding applied. This is aided by its high contrast that gives a crisp appearance to images. This is concentrated on the centre without a doubt, the edges lagging behind, but the fine detail is very good indeed at the centre of the field. The edges are a little disappointing, as is the relatively poor flare control. Overall, a very good lens, not a perfect one, but an excellent, reliable choice for Canon users. Those shooting videos will appreciate the option for a step-less aperture and everyone will enjoy the fast maximum aperture and ability to isolate a subject from their surroundings with shallow depth of field.
And on top of that, it's by far the most expensive option in this comparison. Although it isn't Canon's fasted focusing USM lens, it is fast enough to be effectively employed for some sports uses. And unlike its longer focal length big brother featuring an identical aperture and all but one other lens in this comparison, the 50L is weather sealed with a front filter in place.
While the naming convention Sigma uses for its Global Vision Lenses still confounds us, there's no doubt that Sigma's reputation has been bolstered by its Art and Sports series lenses. High quality construction, sleek styling, excellent optics and reasonable price have become hallmarks of the Sigma brand. Vignetting, flare and CA are all well-controlled.
As is too-frequently typical with third-party lenses, you can expect the Sigma 50 Art to focus less consistently accurately than the typical Canon USM lens.
While results in One Shot mode may leave you scratching your head from time to time, AI Servo performance is noticeably better. I [Sean] have used the Sigma 50 Art for a number of indoor basketball games and, while not perfect, it performs admirably at the task. As Live View uses data coming from the actual sensor to achieve focusing, phase-detect calibration issues can be avoided. Like the Canon, this lens features weather sealing. Flare performance is good at wider apertures but results are less visually pleasing once stopped down to its narrowest aperture.
Chromatic aberrations are decently controlled. The Tamron features the highest maximum magnification 0. For example, if you started out shooting with a Canon T3i and decide to upgrade to a Canon EOS 6D shown above , you don't have to buy a new lens. Better still, many camera manufacturers continue to use the same lens mount as they develop new cameras, so if you're a Canon shooter and you buy a lens in , there's a very good chance that same lens will work on whatever cameras Canon comes out with in the years to come.
If you really want to expand your photographic capabilities, a 50mm lens will allow you to do so because they're great for taking photos when lighting is low. With all that light coming into the lens, that means you can take photos in low lighting without triggering the flash. Since the light from the flash is typically on the harsh and bright side, the fact that you often don't need a flash with a 50mm lens means you can get more natural looking shots. Just think of all the things you can photograph in low lighting with eight times as much light collecting power!
A related feature that's nice about 50mm lenses is that with such a large maximum aperture, you can use much faster shutter speeds. That means that you can shoot handheld in much dimmer lighting than you can with a kit lens by virtue of all that light coming into the 50mm lens. With lower ISO values, your images will have less digital noise, which helps you get even sharper images, even when the lighting isn't all that great.
If you use a 50mm lens on a full frame camera, the angle of view you get closely resembles what we see with our own eyes. It's also advantageous for beginner photographers because as you look through your camera's viewfinder, you'll see the scene in a familiar way, and that will help you compose a better shot. If you have a Nikon D like the one shown above, the crop factor of 1.
At that effective focal length, the lens is in the short telephoto range, so you can more easily fill the frame with your subject from a greater distance away. Prime lenses like the 50mm have yet another benefit that improves the quality of your photos - nice bokeh.
At 50mm, you can get gorgeously blurry backgrounds that are nicely shaped for a wonderful creative effect. Better still, you get that effect right there in-camera, so you don't have to spend a bunch of time trying to do it in Photoshop after the fact! Because it's a fixed focal length, you can't just turn a zoom ring to frame up a different view of a subject.
Instead, you have to use your feet, move around, and work a little harder to frame the shot as you like. What's more, as was mentioned above, it's a versatile lens, so you can try all sorts of photography pursuits without ever having to switch lenses.
