These days, it seems that if you appetite to get a nice aciculate lens, you accept to absorb $1000 on a allotment of L glass. Aside from the chic fifty’s of the world, there are actual few lenses that bear affection after-effects at a low price. But if you attending harder, there are absolutely a few old lenses that still activity amazing affection for acutely low price. How is that possible? Well, it is. Accumulate account to apprentice how.

When Canon appear the EOS arrangement in 1987, they absolutely replaced the old manual-focus FD lenses. FD lenses were adverse with EOS – alone the new EF lenses would work. So Canon appear a lot of affection EF lenses to use with the new cameras. From ’87 till the backward 90s, Canon produced these older-style EF lenses. In the 2000s, best of them were discontinued. Today, they’re about alien to best Canon shooters.

First, a disclaimer: best of these lenses, while actual acceptable quality, are still beneath L glass. Avant-garde advancements accept fabricated amazing improvements in lens technology, which is to be expected. However, if you can’t allow a $1,000 lens, you can’t exhausted the amount these lenses provide.

This lens is apparently the highlight of this post. It’s artlessly a arch lens which is usually awash for beneath $100. Now, Canon produced abounding altered models of 28–80 kit lenses. This one was the first, and the best. Anniversary time they appear a new one, the affection boring went down. This is the one with the USM architecture and the metal mount.

Anyway, now about this lens. As I said, it’s a affection allotment of glass. The angel affection is actual nice, and the body affection is artlessly unparalleled at its accepted amount range. It has a nice metal mount, focus ambit window, and nice focus and zoom rings. Here’s the commodity though: it appearance the fast USM accelerated autofocus motor. This is ring-type USM (there are added types, but ring-type is the best. Added 28–80 lenses accept USM, but it’s not the ring-type like this lens has). AF is fast and snappy. If you charge a accepted walk-around zoom lens on a bound budget, you artlessly can’t exhausted this lens. It additionally makes a abundant advancement for a newer zoom lens.

It is a discontinued model, which agency you’ll accept to acquisition a acclimated one. However, this is acceptable for you, because it’ll be abundant cheaper than your boilerplate new lens. Abounding bodies accept started to apprehension the affection of the Canon 28–80 f/3.5–5.6 USM, which has acquired the amount to go up slightly. But the boilerplate acclimated amount on eBay currently seems to be amid $50 and $100, which is a steal. Absolutely a acceptable advantage for a accepted zoom lens.

This is the telephoto brother to the 28–80 USM. This 70–210mm f/3.5–4.5 lens is actual similar: aforementioned design, construction, and body quality. It sports the aforementioned super-fast autofocus motor. It’s about the aforementioned lens, aloof with a altered focal length. Although not as nice as the avant-garde 70–200 L lenses, it’s absolutely an advantage at about $100. This lens is a abundant advantage if you’re attractive for a account telephoto that will bear appropriate results. The USM motor will be advantageous if you shoot fast activity acute fast AF tracking.

The 100–300mm f/5.6 L lens has the honour of actuality the best arrangement L lens you can buy on the acclimated market. This lens is a archetypal – it goes way aback to the alpha of the EOS arrangement in 1987. You can acquaint how old it is by the push-pull zoom design. But don’t be bamboozled by its looks – the 100–300L performs actual well. It was fabricated up to L standards, including UD and fluorite elements (certain bottle that Canon uses in L lenses), which agency the angel affection is absolutely good. It’s additionally got that admirable ablaze red ring.

This allotment of bottle does accept a few downsides. First, it’s a push-pull zoom, so the operation will be actual altered than the arena zooming begin on avant-garde lenses. Also, it uses Canon’s AFD (arc anatomy drive) autofocus system, which isn’t all that fast like USM. So it’s not an ideal lens for fast-moving sports or any activity that requires AF tracking. But if you’re aloof attractive for some added zoom ability with acceptable angel quality, I absolutely acclaim blockage out this lens. It can be acclimated for macro cutting as well, with its 4.6 ft. minimum focus ambit (MFD). The 100–300L is an old lens, so it’s a bit difficult to acquisition a acceptable acclimated one. There are affluence of them out there though, and if you’re accommodating and you attending for it, you’ll acquisition one.

This is an addition to the 70–210 USM telephoto with a bit added reach. The two lenses accept actual agnate specs and design. The 70–210 has a faster breach but not as abundant reach. The 100–300 f/4.5–5.6 USM is an accomplished advantage for the times back you charge a best telephoto lens. It’s abundant for cutting sports, wildlife, and added action. The USM autofocus motor will accumulate up with the action. This lens gave me lots of accomplished sports and wildlife photos for years afore I upgraded to the 70–200L.

You’re apparently apprehensive why I included two 100–300mm lenses in this post. Well, anniversary has its own advantages. If you shoot a lot of activity and charge AF tracking, the USM motor in the 100–300 USM lens will be accessible for you. You’ll apparently acquisition the AFD motor of the 100–300L to be a bit slow. If, however, you don’t charge fast autofocus, and you’d rather get the advantage in angel affection that an L lens offers, go for the 100–300L. It’s a bit added expensive, but it’s got that red arena and the L angel affection that comes with it.

The 24mm f/2.8 is the alone prime in this group. It’s an old one, appear about a year into the EOS system. But it’s consistently been a abundant lens. For a continued time, this was the alone 24mm prime advantage in the Canon lens calendar (before the two L versions and the contempo IS version). So it’s provided an accomplished wide-angle breadth for years.

I own this lens myself, and it’s my go-to for wide-angle shooting. I adulation this lens – it’s small, light, and inexpensive. But it’s additionally aciculate as a tack. I accumulate this affair on my 5D Mark II best of the time. The 24mm focal breadth is added advantageous for wide-angle if you accept a abounding anatomy camera. 24mm is a nice advanced focal length. However, back acclimated on a crop DSLR, it becomes 36mm… which can be acceptable or bad depending on your needs.

If you’re attractive for a wide-angle lens, 36mm apparently won’t do it for you. But if you appetite a accepted walk-around prime lens that’s a bit added than 50mm, 36mm is great. I’ve begin this focal breadth to be the candied atom for accepted cutting – it’s added than 50mm, but not too wide. In either case, the 24mm f/2.8 is an accomplished little lens that offers amazing amount for its $200 amount tag. I can aboveboard acclaim it as a lens that has becoming a atom in my camera bag.

Here’s addition accepted zoom alternative: the Canon 28–70mm f/2.8 II. This lens is a beast. Don’t let its apprehensive architecture and boilerplate body affection fool you – this lens performs acutely well.

No, it doesn’t accept fast USM autofocus like the 28–80, and the 28–70’s architecture looks a bit old. The focus arena is narrow, and the body affection is artlessly average. But this lens is still a massive value, artlessly because of its glass. The images it produces are actual sharp. Some say the angel affection is on par with L lenses. You can acquisition this lens on eBay for $100 or beneath – a bargain.

If you can’t allow an L lens yet, don’t aloof attending for the cheapest advantage Canon currently offers. If you’re accommodating to buy a acclimated lens, you can get L-like angel affection for a atom of the price. The affection you can acquisition in these lenses for beneath $100 is astounding. So don’t absolute yourself if you can’t allow an L.

You now apperceive a abstruse that best Canon shooters don’t. So booty advantage of it – aces up one of these lenses, shoot some photos, and see for yourself!
