Here's a breakdown of the pros and cons of each:
50mm Lens:
Pros:
* Versatility: The 50mm is a very versatile lens, suitable for a wide range of subjects and shooting situations. It can be used for portraits, street photography, landscapes, and even some macro shots.
* Smaller and Lighter: Typically more compact and lightweight than an 85mm lens, making it easier to carry around and use for extended periods.
* Affordable: Generally more affordable than an 85mm lens, especially the "nifty fifty" versions with wider apertures like f/1.8.
* Wider Field of View: Captures more of the surrounding environment, allowing you to include context and tell a story within your portraits.
* More Room to Work in Tight Spaces: Easier to use indoors or in cramped locations where you might not have enough room to step back with an 85mm.
* Engaging Perspective: Offers a perspective closer to how the human eye sees the world.
Cons:
* Less Subject Isolation: The wider field of view means less background blur (bokeh) compared to an 85mm, so it might not isolate your subject as effectively.
* Requires Closer Proximity: You need to be closer to your subject to fill the frame, which can sometimes feel less comfortable for the subject.
* Can Distort Facial Features at Close Range: If you get too close, a 50mm can slightly distort facial features, especially the nose.
* Less Dramatic Background Compression: Doesn't compress the background as much as an 85mm, which can make the background appear farther away.
85mm Lens:
Pros:
* Beautiful Bokeh: Creates stunning background blur (bokeh) that isolates your subject and makes them stand out beautifully.
* Flattering Perspective: Compresses facial features slightly, which many find to be more flattering for portraits.
* Ideal Working Distance: Allows you to be a comfortable distance from your subject, creating a more relaxed shooting environment.
* Dramatic Background Compression: Compresses the background, making it appear closer and more impactful.
* Excellent Subject Isolation: The narrow field of view and shallow depth of field make it easy to isolate your subject from distracting backgrounds.
* Good for Headshots and Close-ups: The focal length is perfect for capturing detailed headshots and close-up portraits.
Cons:
* Less Versatile: More specialized for portraits and less suitable for other types of photography.
* Larger and Heavier: Typically larger and heavier than a 50mm lens, making it less convenient to carry around.
* More Expensive: Generally more expensive than a 50mm lens.
* Requires More Space: Needs more space to work with, which can be challenging in small studios or indoor locations.
* Less Context: Captures less of the surrounding environment, which might not be ideal if you want to include context in your portraits.
* Can Feel Distant: Some photographers find the distance between themselves and the subject less engaging compared to a 50mm.
Here's a table summarizing the key differences:
| Feature | 50mm | 85mm |
|----------------------|------------------------------------------|-------------------------------------------|
| Versatility | High | Low |
| Size/Weight | Smaller/Lighter | Larger/Heavier |
| Price | More Affordable | More Expensive |
| Field of View | Wider | Narrower |
| Working Distance | Closer | More Distant |
| Bokeh | Less Pronounced | More Pronounced |
| Facial Compression | Less | More |
| Subject Isolation | Less | More |
| Space Requirements | Less | More |
When to Choose a 50mm:
* You want a versatile lens that can be used for portraits and other types of photography.
* You're on a budget.
* You need a lens that's small and lightweight.
* You want to capture more of the environment in your portraits.
* You often shoot in tight spaces.
* You prefer a more natural, engaging perspective.
When to Choose an 85mm:
* You primarily shoot portraits and want the best possible background blur.
* You want a flattering perspective and facial compression.
* You prefer a comfortable working distance from your subject.
* You have plenty of space to work with.
* You want to isolate your subject and minimize distractions.
* You specialize in headshots and close-up portraits.
Ultimately, the best lens for you depends on your individual needs and preferences. Many portrait photographers own both a 50mm and an 85mm and use them in different situations. If you can, try renting or borrowing both lenses to see which one you prefer before making a purchase.
Recommendation:
* Beginner on a Budget: Start with a 50mm f/1.8. It's affordable, versatile, and a great way to learn the fundamentals of portrait photography.
* Serious About Portraits: Consider an 85mm f/1.8 or f/1.4. The image quality and bokeh are worth the investment if portraiture is your primary focus.
* Best of Both Worlds (If Budget Allows): Invest in both lenses for maximum flexibility.
Good luck choosing the perfect lens for your portrait photography!
