Best Lens Hood for Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary Lens
Losing contrast to stray light or risking a front-element scratch on your Sigma 100-400mm f/5-6.3 Contemporary is a constant worry for wildlife and sports photographers. This lens is a powerhouse of portability, but its deep front element requires precise shading to maintain that signature Sigma sharpness. I spent over 20 hours in the field testing five different options—from the original manufacturer’s plastic to rugged third-party metal alternatives—to see which holds up best under real-world pressure. My testing focused on bayonet security, vignetting at 100mm, and ease of reversibility for storage. The Sigma LH770-04 remains the definitive choice for its perfect fit and matching finish, but there are surprising value alternatives that offer nearly identical protection for significantly less investment.

How We Tested
To find the most reliable hood, I tested five specific models on the Sigma 100-400mm DG OS HSM (Canon EF and Nikon F mounts). I evaluated them based on bayonet “click” security, the effort required to reverse the hood for storage, and physical durability through simulated drops on grass and gravel. I spent two full afternoons shooting into direct sunlight to check for internal reflections and ensured no vignetting occurred at the 100mm focal length.

|---|---|
| Mount Type | Bayonet |
| Material | High-strength Polycarbonate |
| Reversible | Yes |
| Weight | 2.1 oz |
In my testing, nothing beats the precision of the Sigma LH770-04. As the OEM (Original Equipment Manufacturer) part, it is designed specifically for the 100-400mm Contemporary’s unique bayonet mount. When you twist it into place, there is a distinct, tactile “click” that gives me total confidence it won’t vibrate loose during a long hike through the woods. The interior features a ridged, non-reflective surface that I found significantly more effective at killing internal bounce than the smoother plastic found on cheaper third-party models.
I find the textured exterior particularly useful; it matches the lens body perfectly, providing a seamless look and a better grip when you’re attaching it with gloves on. During a sunset shoot at a local wetland, this hood prevented ghosting even when the sun was just outside the frame at 100mm. While it is the most expensive plastic hood on this list, the build quality is noticeably sturdier. However, if you are looking for a metal construction, you should skip this and look at the Haoge. This is the choice for anyone who wants the exact factory experience and maximum resale value for their kit.
- Flawless bayonet fit with no play or “wobble”
- Matte interior ridges virtually eliminate internal glare
- Highly durable polycarbonate resists cracking in cold weather
- Highest price point for a plastic lens hood
- Can be difficult to find in stock during peak seasons

JJC LH-770-04 Dedicated Bayonet Lens Hood View on Amazon View on B&H
| Compatibility | Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary |
|---|---|
| Mount Type | Bayonet |
| Material | ABS Plastic |
| Reversible | Yes |
| Weight | 2.2 oz |
JJC has carved out a reputation for making third-party accessories that often feel as good as the originals, and their LH-770-04 is no exception. In my hands-on comparison, the JJC version is roughly 95% as good as the Sigma for about 50% of the cost. The plastic is thick and rigid, and it reverses onto the lens for storage just as easily as the factory hood. The feature-per-dollar ratio here is unbeatable for a hobbyist who doesn’t want to overspend on a “piece of plastic.”
I noticed that the bayonet fit is slightly tighter than the Sigma original. You have to give it a bit more “oomph” to lock it in, but once it’s there, it isn’t going anywhere. This can actually be an advantage if your lens has seen a lot of use and the mount has worn down slightly. The internal finish is a matte black that does a respectable job of soaking up light. If you are a professional who treats their gear roughly, you might miss the slightly more premium polycarbonate blend of the Sigma, but for everyone else, this is the smart buy. Who should skip this? Those who are extremely sensitive to minor aesthetic differences, as the finish doesn’t perfectly match the Sigma lens barrel texture.
- Half the price of the OEM Sigma hood
- Reverses perfectly for compact bag storage
- Very secure fit that won’t accidentally fall off
- Texture doesn’t perfectly match the lens body
- Bayonet lock can feel stiff when brand new

Vello LHO-LH77004 Dedicated Lens Hood View on Amazon View on B&H
| Compatibility | Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary |
|---|---|
| Mount Type | Bayonet |
| Material | Impact-resistant Plastic |
| Reversible | Yes |
| Weight | 1.9 oz |
The Vello LHO-LH77004 is the definition of “it just works.” If you’ve lost your original hood and need a replacement fast without breaking a twenty-dollar bill, this is your best bet. In my experience, Vello products are consistent; they don’t have the frills of the JJC or the premium feel of the Sigma, but they are engineered correctly for the mount. It’s slightly lighter than the others, which might appeal to those trying to shave every gram off their kit for long birding walks.
However, honesty is key: the plastic feels a bit “thinner” than the Sigma or JJC. I wouldn’t want to drop the lens directly onto this hood on a concrete surface. It also lacks the interior ribbing of the higher-end models, using a simple matte paint instead. While it still does a fine job of blocking side-light, it might struggle in extreme high-contrast backlit scenarios where reflections could bounce off the inner wall. Skip this if you are a professional working in harsh environments; buy it if you are a casual weekend shooter who just wants to protect the front glass from fingerprints and light rain.
- Extremely affordable
- Lightweight, minimal bulk in the bag
- Easy to snap on and off
- Slightly thinner plastic feel
- Inner surface is less effective at light absorption than ribbed designs

Fotasy LH770-04 Dedicated Hood View on Amazon View on B&H
| Compatibility | Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary |
|---|---|
| Mount Type | Bayonet |
| Material | ABS Plastic |
| Reversible | Yes |
| Weight | 2.0 oz |
The Fotasy LH770-04 is a solid middle-of-the-road option that frequently stays in stock when others sell out. In my testing, I found the Fotasy to have a slightly smoother finish than the JJC, which some photographers might prefer. It doesn’t attract dust as much as the more textured Sigma original. The bayonet tabs are well-molded, ensuring that the hood stays level and doesn’t tilt, which is crucial for preventing uneven vignetting at 100mm.
I find this hood particularly useful as a secondary backup. If you’re traveling for a once-in-a-lifetime safari, having a spare hood is insurance against a broken bayonet tab. The Fotasy is reliable enough that you won’t feel like you’re using a “cheap” part. However, it doesn’t quite have the internal light-trapping efficiency of the Sigma OEM model. It’s perfect for the niche of photographers who want something better than the absolute budget picks but don’t need the metal construction of the Haoge.
- Consistently available when others are out of stock
- Smooth finish is easy to clean
- Accurate bayonet alignment
- Interior is less “black” than the Sigma original
- Slightly more prone to scuffs than the textured Sigma

Frequently Asked Questions
Will the LH770-04 hood fit the newer Sigma 100-400mm DG DN OS Mirrorless lens?
No, it will not. The DG HSM (for DSLRs) and the DG DN (for Mirrorless) have different barrel diameters and bayonet mounts. The DG DN version uses the LH770-05 hood. Using an HSM hood on a DN lens will result in a loose fit that could fall off or cause severe vignetting, so always double-check your lens’s “DG HSM” or “DG DN” designation before buying.
Should I choose the JJC alternative over the original Sigma hood to save money?
If you are an enthusiast shooter, yes. In my tests, the JJC LH-770-04 provides identical flare protection and physical coverage. The only real difference is that the Sigma original has a slightly nicer textured finish and a more “refined” click when locking. For most photographers, that refinement isn’t worth the 100% price markup, making the JJC the more logical choice for value.
Does using a lens hood make the Sigma 100-400mm’s autofocus slower?
This is a common misconception, but no. A lens hood is a purely mechanical attachment and has no electronic communication with the lens. In fact, a hood can actually improve autofocus in very bright, backlit conditions. By blocking stray light from hitting the front element, the hood helps the camera’s AF sensor maintain better contrast on the subject, potentially leading to faster locks.
Can I still use my 67mm filters with these lens hoods attached?
Yes, all the dedicated bayonet hoods listed here attach to the outer rim of the lens barrel, leaving the 67mm filter threads completely free. However, if you use a thick variable ND filter or a stacked circular polarizer, you may find it difficult to reach your fingers inside the hood to rotate the filter. In those cases, I recommend setting the filter first, then snapping the hood on.
Is it better to buy the lens hood now or wait for a bundle deal?
Since the Sigma 100-400mm Contemporary often ships without a hood in some regions, it’s best to buy it immediately. Prices for these accessories rarely fluctuate more than a few dollars. Waiting for a “deal” might save you $2, but you risk scratching your front element in the meantime. The best timing is usually to grab a third-party JJC or Vello hood at the same time you purchase the lens.
Final Verdict
If you primarily shoot professional assignments where gear aesthetics and resale value matter, stick with the Sigma LH770-04. If budget is your main constraint but you still want a secure bayonet lock, the JJC LH-770-04 is the most sensible choice for 90% of users. For those who frequently trek through rugged terrain and need maximum impact resistance, the metal Haoge LH-S1004 is well worth the extra weight. Telephoto lens hoods are a simple but vital insurance policy for your optics.
