The large sensor of full-frame cameras makes it difficult to offer lenses that offer a wide range of focal lengths without the lens becoming unfeasibly large. The 24-105mm F4 strikes a nice balance, though. Extending from the usefully wide-angle 24mm out into the portrait-friendly mid-telephoto region at 105mm, it makes a solid 'whatever happens' lens.

We don't usually test a product for ten years before reviewing it, but after a decade of using the Lowepro Photo Sport 300 AW II on an almost daily basis, Managing Editor Dale Baskin tells us why he loves this pack.

The latest 16-35mm F2.8 from Canon is one of the best wide-angle zooms in the world. It's astonishingly sharp even at wide apertures.

Growing in a meadow bathed in sunlight, the left shot is as found with the sun shining directly on the orchid and the grass behind. By using a small diffuser to block out the sun falling on the orchid only and not on the background, resulted in an enhanced tonal variation of light reflected from the two. The background appears brighter because I had to re-meter the flower and adjust the exposure. This can be a useful way of separating a subject which has a similar colour and tone from the background – notably grasses against green vegetation.

Canon's latest 70-200mm F4L comes with a five stops of image stabilization, a new coat of paint and impressive sharpness. We've been shooting with our copy for several weeks now - see how it stacks up in our sample gallery.

There is no better way of appreciating just how effective a diffuser can be at reducing high contrast and strong shadows than by taking comparative shots with and without one. Carrying a diffuser is the equivalent to having your own portable miniature cloud for use on sunny days.

The 35mm F1.4 Art offers one of the most flexible do-everything focal lengths, paired with excellent image quality at a sensible price. There are plenty of choices of other focal lengths available for full-frame Canon, but unless you have a specific use in mind, the 35mm F1.4 makes a great all-rounder.

The Sigma 70mm F2.8 is a long-established lower-cost alternative to the Canon 100mm Macro. The shorter focal length means having to get a bit closer to your subject and there's no clever IS, but it's a good way to experiment with Macro.

Sigma's 24-70mm F2.8 covers a classically useful range with a bright enough maximum aperture to help you get the most out of your full-frame camera. While image quality doesn't match the impeccable standards of Sigma's prime / fixed focal length 'Art' lenses, it's still very good, and costs less than Canon's own take on this workhorse lens type.

Canon's 16-35mm F4 IS is a fairly bright, optically reliable wide-angle zoom. The addition of image stabilization makes it easy to shoot a variety of wide-angle subjects, particularly in lower light.

The Tamron 17-35mm doesn't go quite as wide as the Canon, nor does it have image stabilization, but its F2.8-4 maximum aperture adds flexibility to a well-priced lens choice.

Standard zooms are just what they sound like - versatile, general-purpose lenses that start with a fairly wide angle of view and allow you to zoom in to a focal length traditionally used for portraits.

The stabilized version of Canon's 70-200mm F4 L offers an excellent balance of size, price and image quality. It focuses fast enough for sports shooting and offers a classic, flexible telephoto range. The lighter weight and solid optical performance make it worth considering rather than 3rd-party F2.8 alternatives.

I am often asked what is my favourite lighting. Since no type of light suits all subjects, I don’t favour any particular one. However, soft diffused light gives stunning results for many flowers – especially pastel-toned ones; whereas direct sunlight is good for bold reds and oranges and creating shadows that can add a dynamic element to the composition.

The Tamron is unusual in being able to offer the semi-wide to long tele range of 28-300mm. The maximum aperture drops to a pretty slow F6.3 at the long end but it fits a lot of flexibility into a sensibly-sized package.

The 70-200mm F2.8 L III is another of Canon's workhorse lenses used and trusted by professionals across the world. Its performance and build quality are as impressive as that demands.

If you've got a bit more to spend on a 35mm lens, the latest version of Canon's F1.4 is simply superlative optically, and is extremely well built to boot.

The Canon 100mm F2.8 Macro is an update to what was already considered a classic lens. The Hybrid IS system is designed specifically to correct for the kinds of motion that can plague macro photography, making it a useful additional to an optically excellent lens.

Telephoto lenses start out being fairly zoomed-in, and allow you to zoom in further so you can fill your frame with more distant subjects.

The second shot is more restful to the eye. It also more informative since it reveals the ground beneath the crocuses is carpeted with attractively patterned cyclamen leaves.

The Tamron 85mm F1.8 isn't just sharp and well-priced: it’s also image stabilized. And, while image stabilization won’t prevent your subject from moving, it can help maximize shooting opportunities in borderline situations as well as letting you shoot with longer shutter speeds.

These three comparative pairs show how dramatically diffused light can change the appearance and mood of a close-up subject.  By experimenting, you will soon appreciate that some subjects work fine when lit with direct light, while others are enhanced by diffused light.

Travel zooms are like your standard zoom lens but taken to the extreme. You still start out with a fairly wide field of view, but you can zoom in almost as much as many telephoto lenses. This is convenient, but these lenses tend to let less light through them, so aren't as useful in dimly lit situations, and they may not always give you the sharpest results.

Leica has announced the Q3 43, a variant of its full-frame fixed lens compact with a 43mm F2.0 normal lens. We've had the chance to use and test it, to produce an in-depth review.

The aperture was kept constant for both shots at f/11. In sunlight the ISO was 160 and the exposure 1/400 at f/11. With a diffuser used for the right-hand shot, I pushed the ISO up to 400 and the exposure was then 1/250 at f/11.

Unlike the chestnut coloured conkers produced by the European horse chestnut (Aesculus hippocastanum), those of Indian horse chestnut (A. indica) conkers are dark brown. They were discovered lit by strong sunlight, when the texture within the deep tones were lost by the conspicuous catchlights from the sun. So a diffuser was used to even out the light and eliminate the harsh shadows.

The first pair of images feature a crocus. On the left, the flower is spotlit by sun beaming through trees at 4:10pm in March. The result is a dramatically lit flower emerging from its surroundings completely in shadow with no hint of the adjacent plants. When a large Lastolite Tri-grip diffuser was held between the sun and the crocus, this dramatically reduced the contrast (and the light level by two stops). Whenever a diffuser is used, the light needs to be re-metered with it in position. The exposure for the first shot was 1/30 sec at f/18 and, with a diffuser, I retained the same aperture and changed the shutter speed with an exposure of 1/8 sec at f/18.

Canon's 24-70mm F4 offers is smaller and lighter than F2.8 versions while still offering the image quality to qualify as part of the company's 'L' range. It's a entire stop slower than the F2.8s but still an upgrade from most variable aperture lenses.

Above $2500 cameras tend to become increasingly specialized, making it difficult to select a 'best' option. We case our eye over the options costing more than $2500 but less than $4000, to find the best all-rounder.

The Sigma 85mm F1.4 Art is one of the best lenses available for any system. It offers impressive sharpness and excellent all-round performance at a lower price than most camera maker’s own optics. It’s a pretty substantial lens, but well worth the weight.

A faster sensor, improved autofocus and video see Nikon's third-gen mid-range full-framer go toe-to-toe against Canon's EOS R6 II and the Sony a7 IV. We feel its all-round ability lifts it to the top of the pile.

The Canon 24-70mm F2.8 L is one of the most widely-used professional lenses in the world. It's fast, solidly-built and well-respected for its image quality.

The Tamron 70-210mm F4 offers a less-expensive alternative to Canon's L version. It doesn't quite match the Canon in terms of build but it's a strong choice, nonetheless.

Prime lenses are just a single focal length; removing the complexity of a zoom often allows for these lenses to be smaller, lighter and sharper, while letting more light through and being more useful in dimly lit situations.

Some people will choose the Canon 85mm F1.4 over the Sigma because they want to stay on-brand, while other people will appreciate that it’s a touch smaller and lighter. It’s an excellent lens, whatever your motivation.
