How to choose a good ultra-wide-angle lens

I’ve recently decided to rekindle my passion for photography. While I’ve been using a compact digital camera (Panasonic DMC-ZR1) for casual shots, it’s time to return to more serious gear. Ideally, I’d love to shoot with medium format cameras like 4×5 or 6×6, but their steep prices keep them out of reach for now. Instead, I’ll start with a 35mm system as my re-entry point.

Fortunately, I already own a Nikon FM2, a film SLR handed down from my family. To maintain compatibility with my existing lenses, I naturally opted for a Nikon DSLR. After some research, the D90 emerged as the best fit for my current needs. Since my studio has upcoming projects requiring wide-angle shots, I decided to skip the kit lens and pair the body with an ultra-wide-angle zoom instead.

Below is a comparison of third-party ultra-wide-angle zoom lenses available on the market (I excluded Nikon’s own offerings due to their premium pricing).

After spending an entire day scouring reviews and sample images, I found myself torn between the Tamron 10-24mm and the older Sigma 10-20mm F4-5.6. Both are excellent lenses, but each has distinct characteristics that reflect their manufacturers’ design philosophies.

Why I’m Leaning Toward the Tamron 10-24mm

1. Longer Focal Range – The extra 4mm on the wide end is useful for versatility.
2. Full-Frame Compatibility – Future-proof if I upgrade to FX (or use it on my FM2).
3. Better Center Sharpness – While edge performance is softer, the center is noticeably sharper than the Sigma.
4. Superior Flare Resistance – Handles backlit scenes more effectively.
5. Price Difference – At NT$3,600 cheaper (as of Feb 8, 2011), the savings could go toward a good CPL filter.

That said, the Sigma 10-20mm F3.5 and 12-24mm are also strong contenders—if not for their higher price tags. Meanwhile, the Tokina 11-16mm F2.8 boasts outstanding resolution, though its narrower zoom range might be limiting. I haven’t ruled it out entirely; it could still be a dark horse in this race.

Final Thoughts

Understanding my own priorities—sharpness, versatility, and future compatibility—helped narrow down the choices. While no lens is perfect, the Tamron 10-24mm seems to strike the best balance for my needs. Still, I’ll sleep on it before making the final call.
