Why it's a good contender:
* Sharpness: Reports and reviews generally indicate good sharpness, especially in the center, even wide open at f/2. This is crucial for portrait lenses.
* Bokeh: The f/2 aperture combined with the 75mm focal length creates a pleasing shallow depth of field and smooth, creamy bokeh (background blur), which is highly desirable for portraits.
* Autofocus: The inclusion of autofocus is a huge plus at this price point. While not as lightning-fast as higher-end lenses, it's generally considered accurate and reliable for portrait work.
* Price: This is the biggest selling point. It's significantly cheaper than most native 85mm portrait lenses from major manufacturers.
* Build Quality: While budget-friendly, the build quality is often reported as being surprisingly good for the price. Many reviewers note a solid, metal construction.
* Compact Size: More compact than many other portrait lenses, making it easier to carry and use.
Potential Drawbacks (Things to Consider):
* Autofocus Speed: As mentioned above, the autofocus isn't the fastest. It might struggle in very low light or with fast-moving subjects. It's likely good enough for posed portraits, but might be frustrating for action shots or capturing fleeting moments.
* Chromatic Aberration (CA): Some reviewers have noted the presence of chromatic aberration (purple fringing) in high-contrast areas, particularly when shooting wide open. This can often be corrected in post-processing.
* Vignetting: Vignetting (darkening of the corners) can also occur, especially wide open. This can also be corrected in post-processing, or used creatively.
* Brand Reputation: TTArtisan is a relatively new player in the lens market. While their lenses have generally received positive feedback, their long-term reliability and customer support might not be as established as more well-known brands.
* Alternatives: Depending on your camera system, there might be other budget-friendly portrait lenses (e.g., adapted vintage lenses or other third-party options) that could be worth considering.
Who is it best for?
* Budget-conscious photographers: If you're looking for a dedicated portrait lens without breaking the bank, this is an excellent option.
* Hobbyist portrait shooters: If you primarily shoot portraits as a hobby and don't need the absolute best performance, the TTArtisan is a great value.
* Photographers who are willing to do some post-processing: Minor corrections for chromatic aberration or vignetting may be needed, but the image quality is generally good enough to make it worthwhile.
Who might want to look elsewhere?
* Professional photographers: If you need the absolute best image quality, fastest autofocus, and most reliable performance, a more expensive native lens is likely a better choice.
* Photographers who shoot in challenging lighting conditions: The slower autofocus may be a limitation in low-light situations or when photographing fast-moving subjects.
* Photographers who prioritize convenience: If you want a lens with minimal distortion or aberrations that require correction, you might want to invest in a higher-end option.
In conclusion:
The TTArtisan AF 75mm f/2 is a very compelling option for a budget portrait lens. Its strengths include sharpness, pleasing bokeh, autofocus, and a low price. However, you need to be aware of its potential weaknesses, such as slower autofocus and the possibility of chromatic aberration or vignetting.
To decide if it's *the* best for you, consider:
* Your budget: How much are you willing to spend?
* Your shooting style: What kind of portraits do you shoot (posed, candid, fast-moving)?
* Your camera system: Are there other affordable portrait lenses available for your camera?
* Your willingness to post-process: Are you comfortable making minor corrections in editing software?
Read reviews, watch video comparisons, and if possible, try the lens out yourself to see if it meets your needs. Good luck!
