Home/Photography, Review/Best Canon Ef 50mm F 1.8 STM Lens Review 2017

The Canon EF 50mm f1.8 STM digital camera lens has been created for photographers ready to upgrade the performance of their stock digital cameras. The following review will cover a camera lens buyer’s guide, important product features, and actual user experiences with the Canon EF 50mm f1.8 STM. Before we look at the Canon lens features let’s outline some tips for buying the right lens for your photography needs.

 Canon EF 50mm f 1.8 STM Lens Features and Capabilities

The Canon EF50mm f 1.8 STM lens is the perfect upgrade to any stock Canon digital camera lens. It offers a 50mm fixed focal length, 1.8 aperture, smooth operating autofocus and a metal base for greater durability. It easily handles portrait work, sports, and action shots, and it’s a natural for nighttime photos too. It also features a tight 1.15 ft closest focusing distance and a 49mm filter.

The basic design difference between the EF 50mm f1.8 STM and your stock Canon lens is that the EF 50mm is a fixed focal length lens and your stock lens is an adjustable focal length lens that allows you to zoom in and out to frame your subject from a fixed position. The advantages of this difference really outweigh the disadvantages once you get used to life without the zoom feature.

If you’re not sure you can live without a zoom lens just experiment with your stock lens by setting it at 50mm and leaving it there while taking some photos. Most people soon adjust to the fixed focal length and enjoy the greater quality and creative features of the EF 50mm f/1.8 STM lens. The benefit of the 1.8 aperture is the narrower depth of field it provides.

This allows you to blur the background so your image focal point really pops. It also allows you to work in much lower light situations than your stock lens’ 3.5-5.6 apertures. You’ll need to be careful not to lose focus at the 1.8 to 2.8 aperture setting because of a narrower depth of field though.

Try setting the focus to single point and using the eyes of your subject as the focus area to get the best results.Comparing the build quality of the Canon EF 50mm f 1.8 STM to your stock lens will leave you wondering why you didn’t upgrade sooner. The stock lenses have plastic mounts so the upgrade to the metal base is noticeable immediately.

Not only will this upgrade improve durability it will also make the camera feel more stable while shooting. The autofocus system is a major upgrade as well. Featuring a geared stepping motor it performs quietly whether you have it set to continuous movie or still photo autofocus modes.

Actual User Feedback

The best reviews of a product like the Canon EF 50mm f 1.8 STM lens come from actual users. Here are few helpful comments from people who own this lens.

“I was shopping for an entry level Canon lens that could help me take photos with that background blur or “bokeh” effect. I couldn’t have made a better a better decision when I purchased this camera lens. Even though I’m a relative newbie to photography once I got this lens my photos really are more professional looking. The lens also has improved my creativity by inspiring me to experiment with varying lighting setups. Best of all the improved image quality allows me to produce photos that require little if any touch ups.”

“This is a very good lens for the price. Unless you already have high-end 50mm lens it’s will take better photos than what you have now. The lens produces sharp photos and is fast enough for portraits and almost any other type of photography. The manual focus by wire feature takes some practice but the STM is smooth. The one I have isn’t silent enough not to be picked up by my internal microphone so I use an external microphone when shooting in movie mode.”

In closing, the Canon EF 50mm f 1.8 STM digital camera lens is a very good lens for the money. It provides all the features and build quality any photographer could want. This prime lens provides professional quality features that allow any photographer to produce beautiful photographs. Just remember it’s not a zoom lens and don’t let that bother you either. Once you see the improved colors, sharpness, and flexibility of this lens provides you’ll leave your old stock zoom lens in the bag.

Digital Camera Lens Buyer’s Guide

This short guide is designed to help the reader understand the basics of digital camera lenses. Hopefully, this knowledge will help as you search for a lens to take your photography to the next level.

Most photographers believe the lens is the critical component of any camera. The quality of the camera lens affects sharpness, color quality, and most importantly the photographer’s creativity. At some point, every photographer asks “Which lens do I need to buy next?” To answer that question the photographer must know what types of photos they want to make and understand what lens will help them the most. The 4 key characteristics of the camera lens to consider are: focal length, Maximum aperture, Format, and Lens Mount.

  • Focal length – Is the lens’s angle of view and is listed in mm. The larger the number equates to more zoom while a smaller number provides the ability for wider angle shots.
  • Maximum Aperture – measures the amount of light the lens can gather. The smaller the apeture number the greater the light gathering ability of the lens.
  • Format – determines that the lens is matched to the image sensor of the camera.
  • Lens mount – camera manufacturers design proprietary mounts so it’s very important to know your camera’s lens mount design when purchasing a new lens.
