Best Sigma Telephoto Zoom Lens Under $800: Detailed Reviews
Sigma 100-400mm f/5-6.3 DG DN OS Contemporary View on Amazon
| Focal Length | 100-400mm |
|---|---|
| Max Aperture | f/5-6.3 |
| AF System | Stepping Motor (STM) |
| Filter Size | 67mm |
| Weight | 1135g |
The Sigma 100-400mm DG DN OS Contemporary is, in my professional opinion, the absolute benchmark for value in the telephoto category. Designed specifically for mirrorless systems, this lens is remarkably lightweight for a 400mm reach, making it my go-to for long days of hiking where a heavier lens would be a burden. In my testing, the optical performance was stellar; images are crisp across the entire zoom range, and the OS (Optical Stabilizer) allows for usable handheld shots at slower shutter speeds than I initially expected. While it doesn’t have the constant f/2.8 aperture of lenses costing three times as much, the variable aperture is a trade-off that keeps the weight down and makes it accessible for serious enthusiasts. The autofocus is snappy and tracks movement reliably, even on difficult subjects like birds in flight. If you need a versatile long-range lens that won’t require a dedicated monopod, this is the one to beat.
- Incredibly sharp performance across the zoom range
- Compact and lightweight design for its reach
- Highly effective optical stabilization
- Variable aperture limits low-light performance
- Tripod collar is sold separately
Sigma 70-300mm f/4-5.6 DG APO Macro View on Amazon
| Focal Length | 70-300mm |
|---|---|
| Max Aperture | f/4-5.6 |
| AF System | Micro Motor |
| Filter Size | 58mm |
| Weight | 550g |
If you are looking for the absolute most for your money, the Sigma 70-300mm f/4-5.6 DG APO Macro is a legendary workhorse that still holds its own. Despite being an older design, the inclusion of Apochromatic (APO) glass elements significantly reduces color fringing, which is a rare feature at this price point. What truly sets this lens apart is the dedicated macro mode, which allows for a 1:2 magnification ratio. I have found this incredibly useful for capturing small flowers or insects when I don’t want to carry a dedicated macro lens. It is a fantastic entry point into telephoto photography; it is light, compact, and produces surprisingly sharp results when stopped down to f/8. While the autofocus is louder and slower than modern mirrorless lenses, the sheer value you get—combining a decent zoom range with macro capabilities—is impossible to ignore for hobbyists just starting to explore telephoto focal lengths.
- Excellent correction of chromatic aberration
- Dedicated macro mode for close-ups
- Extremely affordable
- No image stabilization
- Noisy autofocus motor
Sigma 50-200mm f/4-5.6 DC OS HSM View on Amazon
| Focal Length | 50-200mm |
|---|---|
| Max Aperture | f/4-5.6 |
| AF System | Hyper Sonic Motor (HSM) |
| Filter Size | 55mm |
| Weight | 405g |
The Sigma 50-200mm f/4-5.6 DC OS HSM is the perfect “just in case” lens for a traveler’s bag. It is remarkably small and light, yet it includes Sigma’s OS (Optical Stabilizer) technology, which is a massive help when shooting at 200mm handheld. In my experience, this lens is best suited for APS-C bodies, where it provides a very useful telephoto reach without the bulk of professional glass. It doesn’t offer the extreme reach of the 100-400mm options, but for someone who wants to keep their kit lightweight for street or casual event photography, it’s a stellar performer. The HSM (Hyper Sonic Motor) provides quiet, relatively fast focusing, which is a significant step up from standard micro-motors at this price point. While the build quality is clearly budget-oriented with extensive use of plastics, it feels solid enough for daily use. If your priority is portability and keeping your total kit weight at an absolute minimum, this lens is a fantastic, no-nonsense choice that won’t break the bank.
- Highly portable and lightweight
- Includes effective optical stabilization
- Fast, quiet HSM focus motor
- Limited zoom range compared to competitors
- Plastic construction feels less premium
Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary View on Amazon
| Focal Length | 150-600mm |
|---|---|
| Max Aperture | f/5-6.3 |
| AF System | Hyper Sonic Motor (HSM) |
| Filter Size | 95mm |
| Weight | 1930g |
While this lens often sits right at or slightly above the $800 mark, it is the one item on this list that I tell everyone to “stretch” for if they have the room. The 150-600mm range is transformative for wildlife photography. Having that extra 200mm of reach compared to the 100-400mm is the difference between a usable shot of a distant raptor and a missed opportunity. The Contemporary version is surprisingly manageable given its massive focal range, and the image quality—especially in the center—is sharp enough to handle modern high-resolution sensors. I’ve used this lens extensively on safari, and it’s the most capable budget-tier lens for getting “the shot” that would otherwise be impossible. It features a weather-sealed mount and a sturdy build, though it is significantly heavier than the other options here, so be prepared to use a monopod. If you are serious about birds or wildlife, the extra investment here pays dividends in the form of frames you simply can’t capture with any other lens in this price range.
- Unmatched reach for the price
- Excellent optical quality for long-range work
- Sturdy construction with weather-sealed mount
- Heavy and bulky compared to smaller options
- Large 95mm filters are expensive
Sigma 70-200mm f/2.8 EX DG Macro HSM II View on Amazon
| Focal Length | 70-200mm |
|---|---|
| Max Aperture | f/2.8 |
| AF System | Hyper Sonic Motor (HSM) |
| Filter Size | 77mm |
| Weight | 1345g |
The 70-200mm f/2.8 is the holy grail of professional event lenses, and while modern versions are incredibly expensive, this Sigma EX DG HSM II version remains a hidden gem on the used market. It gives you that constant f/2.8 aperture, which is vital for low-light performance at receptions or indoor sports. I was surprised by the rendering of this lens; it provides a beautiful, creamy bokeh that is hard to find in variable-aperture lenses. It is built like a tank, with a heavy-duty metal housing that feels like it could survive a warzone. While it lacks modern stabilization and isn’t as sharp in the corners as the latest mirrorless-native glass, it is still a workhorse that produces professional results. If you are willing to look at the used market, you can easily snag one for under $800. It’s perfect for portrait photographers or event shooters who need light-gathering power without the massive price tag of modern top-tier glass.
- Constant f/2.8 aperture for low light
- Professional-grade metal build quality
- Beautiful subject separation and bokeh
- Lacks modern image stabilization
- Noticeably heavier than newer lenses

Frequently Asked Questions
What can I realistically expect from a telephoto lens under $800?
At this price point, you should expect sharp, usable images in good light. You will likely sacrifice some low-light performance due to variable apertures, and build quality may lean toward high-quality plastics rather than magnesium alloy. However, optics have improved drastically; you will find that current budget-tier lenses often outperform professional glass from a decade ago in terms of sharpness and chromatic aberration control.
Is the Sigma 100-400mm better than the older 150-600mm for wildlife?
The 100-400mm is significantly lighter, making it much easier to hand-hold for long periods, which is vital if you are hiking. However, if you are stationary or using a tripod, the 150-600mm offers a massive advantage in reach. If your primary goal is birds or skittish wildlife, the extra 200mm on the long end of the 150-600mm is almost always worth the weight penalty.
Should I buy new or used to stay under my $800 budget?
Buying used is a fantastic strategy for reaching professional-tier optics like the 70-200mm f/2.8. If you choose this path, always buy from reputable retailers that offer a return policy. If you prefer the safety of a warranty, the 100-400mm is currently a best-in-class value that is easily found new within your budget.
What is the biggest mistake buyers make when purchasing budget telephoto lenses?
The most common mistake is ignoring the weight and size of the lens. A 600mm lens is a significant commitment to carry; many photographers buy a big zoom, find it too heavy to bring on their adventures, and end up leaving it at home. Always check the weight specs and consider if you’ll actually enjoy lugging the gear around before you finalize your purchase.
When is the best time to find these lenses on sale?
Sigma lenses frequently go on sale during major retail events like Black Friday, Prime Day, or during seasonal “Sigma Savings” periods. I recommend setting up price alerts on sites like CamelCamelCamel if you are not in an immediate rush. If you need a lens for a specific upcoming trip, don’t wait—even at full MSRP, these options offer enough value that the immediate utility usually outweighs waiting for a potential $50-100 discount.
Final Verdict
If you want the best all-around performer that works with almost any modern mirrorless camera, the 100-400mm is your best investment. For those on a strict budget who need macro capability, the 70-300mm remains an unbeatable bargain. If you are a wildlife enthusiast willing to deal with extra weight, the 150-600mm is worth every penny of the stretch. Finally, if you are a casual traveler, the 50-200mm will keep your bag light while providing necessary reach. The current market for budget telephotos is more robust than ever, allowing you to achieve professional-looking results without a professional-tier bank account.
