One of the best ways to understand the concept of focal length is to capture images of the same subject using different lenses.

The TREMOR3™ reticle is designed to maximize the speed and accuracy of marksmen. Its unique use of patented features gives users the capability to quickly estimate the range to targets while also giving the user wind speed and drop correction information for fast and accurate Second Shot Corrections. Visit the Horus website for more information.

The example of the ferries wheel illustrates the way that many people think about lenses. You use wide angle lenses to capture a wide view of the world and you use telephoto lenses to capture images of things far away. But you need to shift that thinking to to truly understand lenses and focal length.

It is also important to understand that the size of your sensor affects your focal length. “Full Frame”, “FF” or “FX” sensors are the same size as 35mm film (24mm by 36mm). Cameras with these larger sensors tend to be more expensive that crop sensor cameras with smaller sensors.

A traditional reticle, calibrated in mils, giving shooters the added ability to take long range shots with a high degree of precision.

Subtended in 2 MOA increments with integrated ½ MOA measuring bars, the RMG MOA allows shooters to apply elevation and windage holds without having to dial the turrets. A floating centre dot ensures a refined point of aim for zeroing and shooting groups, while the heavy bars with chevron ends at 3, 6, 9 and 12 o’clock help draw the shooter’s eye to the centre of the reticle at lower magnifications.

It’s the ideal choice for hunters and shooters looking for pinpoint precision as well as the ability to make high speed, snap shots on moving targets and game.

I have heard photographers say that they don’t need a wide angle lens because they don’t really like landscape photography. And if they need get more into the scene then they can just back up.

Designed with precision shooting in mind, the PHR 3 delivers many of the benefits of the PHR ll reticle, in a simplified format.

Whether holding elevation and windage for high speed, precision shots or dialling your turrets for long range targets, the RMG 2 is the perfect blend of precision and speed, now with extended windage and elevation.Subtended in 0.5 mil increments with integrated 0.1 mil measuring bars, the RMG 2 allows shooters to apply elevation and windage holds without having to dial the turrets. A floating centre dot ensures a refined point of aim for zeroing and shooting groups, while the heavy bars with chevron ends at 3, 6, 9 and 12 o’clock help draw the shooter’s eye to the centre of the reticle at lower magnifications.The illumination feature has been carefully designed to allow maximum usability of the reticle in all environmental conditions, whilst permitting effective shot placement at shorter ranges on lower magnification settings.

It is really important for photographers to understand how their different focal lenses see the world because they will be able to choose the lens that fits their vision for the image they have in their mind.

Here are some more examples of how focal length affects your image. Be sure to pay attention to the size of the objects in the background.

A floating centre cross allows for a refined point of aim whilst losing none of the ‘pointability’ of a traditional hunting reticle.

While they might be able to back up, the image they capture will be different. You can’t just replicate the look of a wide angle lens by backing up with a longer lens. Just like you can’t replicate the way a long telephoto sees the world by getting closer. It doesn’t work that way.

RAR Illuminated reticle allows for rapid target acquisition and speed shooting, yet enables precision shots when required. The heavy outer bars taper to sharp and precise points, leading the shooters eye naturally to the centre of the reticle. Incorporation of a segmented ¾ illuminated circle and centre dot make speed shooting a breeze. Integrated 2 MOA hash marks and numbered 4 MOA elevation intervals give shooters the ability to account for wind and bullet drop.

Whether holding elevation and windage for high speed, precision shots or dialling your turrets for long range targets, the RMG (Refined Mil Grid) is the perfect blend of precision and speed.

There are two things to notice in this series of images using different focal lengths. 1. The size of the tree and the rubbish bin the background 2. How the shape of the bench changes and becomes more compressed the longer the focal length is used.

The OSR enables the largest possible field of view due to its offset design whilst retaining all the benefits of a FFP reticle. When precision and speed matter, the OSR is the perfect companion.

When comparing the two images, the shape of the truck and the compression of the parts of the image are very different. I moved back away from the truck for the 105mm focal length image.

So wide angle lenses like the 14-24mm F2.8 have a wide field of view and telephoto lenses like the 70-200mm F2.8 have a narrower field of view.

The R3 features a floating centre dot and subtensions of 1 MOA marked by dots with a hash mark every 4 MOA. Heavy bars at 3, 6, 9 and 12 o’clock make target acquisition a breeze.

Unobtrusive elevation holds are available at 1.1, 2.5, 5, 10, 15, 20 and 25 MOA, allowing the shooter to maximise the potential of their rifle and ammunition combination.

Precision – Simplicity – Speed. The LR Hunter has been developed for shooters and hunters who are looking for a ‘do it all’ reticle. The combination of First Focal Plane (FFP) and adjustable illumination enables the LR Hunter to mimic traditional reticles on low magnification. Whilst at higher powers, a level of precision is on offer to help you connect with the farthest targets. The LR Hunter is a true hybrid.

Unobtrusive elevation holds are available at 2.5, 5, 10, 15, 20 and 25 MOA, allowing the shooter to maximise the potential of their rifle and ammunition combination.

A 100mm lens on a full frame camera will act like a 150mm lens on a 1.5X cropped sensor camera or like a 160mm lens on a 1.6X cropped sensor camera. So this will affect the field of view of your lens.

The R3 reticle allows the shooter to enjoy all aspects of a second focal plane (SFP) scope without losing the ability to ‘hold over’ with extreme precision for long range shots.

Subtended in 0.5 mil increments with integrated 0.1 mil measuring bars, the RMG allows shooters to apply elevation and windage holds without having to dial the turrets. A floating centre dot ensures a refined point of aim for zeroing and shooting groups, while the heavy bars with chevron ends at 3, 6, 9 and 12 o’clock help draw the shooter’s eye to the centre of the reticle at lower magnifications.

Start with your widest angle lens and make sure your subject is in a position where there is something in the background (so not right up against a wall). Get close to the subject so you can almost fill the frame with the foreground subject and capture an image. Then select a longer focal length and back away from your subject so you can fill the frame with the foreground subject and still see the same thing in the background. Compare the images. You can actually do this for multiple focal lengths and not just your widest and longest focal lengths.

Understanding focal lengths is incredibly important in photography. You need to understand how different focal lengths see the world because that will enable you to choose the best focal length for your image.

The PHR II shares all the features of the PHR reticle with the addition of a floating centre dot for an ultra-refined point of aim as well as a finer 6 o’clock post, enabling even more precise elevation ‘hold overs’.

Focal length is a number represented in mm that tells you the angle of view that your lens will capture. The lower the focal length number, the wider the angle of view. For example, a 14mm lens has an angle of view of 114 degrees while a 200mm lens has a focal length of 12 degrees.

Unobtrusive elevation holds are available at 1.1, 2.5, 5, 10, 15, 20 and 25 MOA, allowing the shooter to maximize the potential of their rifle and ammunition combination.
