Photax Paragon 135mm f/3.5

Quality Canon Lens Recently used my new 18-135mm lens on my SL3 Rebel and was surprised and delighted how quickly the USM autofocus worked, even in low light indoor settings. The barrel lock is a welcome feature, to avoid any zoom creep if and when the lens gets worn down over time. I plan to use this lens as my primary EF-S walkabout lens, as it has such a great mid range from wide angle to medium telephoto zoom. I look forward to capturing a lot of moments with this versatile lens

Get it? Got it. Good. In the last couple of years I've had a ridiculous number of lenses. You can read all the reviews that you like. There's nothing like having the pieces in your hands and using them on your cameras. Some reasonably priced lenses, for instance the 24mm pancake, the 50mm prime, and the 85mm prime, have been consistently crisp and clear. Just excellent units at pretty low prices. You can't ask for better than that. The thing there is that traditionally, prime lenses were sharper and more consistently exhibited better focus than zoom lenses. That's changed. With primes, you carry a few of them. Zooms are really convenient. Convenience versus clarity is a decision that's no longer necessarily one that need be made. The 18-135mm USM Nano and the 70-300mm USM Nano are so much better than the other zooms that I've used that one must applaud the advances that have been made. They're not that expensive, not really at all, yet they regularly give me on point focus on the level that my primes did. Crisp focus with the convenience of a zoom at a nice price? That's something of a no brainer. Sure, L Series zoom lenses did and do offer clarity at the high level of primes. They do so though at a high retail price and they're big, clunky, and heavy. Yes, they're beautifully made and a pleasure to use if you don't mind lugging around a big lead weight or two. There are two lenses in my bag now. The 18-135 Nano and the 70-300 Nano. They cover a vast range and perform flawlessly. Why play around with lesser lenses when there's very little difference in price? Now I can understand Pros using L Series lenses for their superior light gathering capabilities. If you don't need that capability and don't care about the status that showing up with a fancy L Series lens confers, play it smart. Get one of these. You get great photos and you can snicker quietly at those that just don't get it.Read full review

Very versatle lens. I got this to replace my Canon 15-85. I liked the 15-85, but my Canon 10-18 covered the 15-17 range. I wanted a longer all around focal length. The 18-135 USM also has a greater magnification for close ups. Since it has a 67mm filter it matches the 10-18, so I wont need step up rings when carrying the 10-18 and 18-135 together. There have been situations when I carried the 10-18 and 15-85, but wished I had a longer length than 85. This lens provides that. I will also be selling my 55-250 STM, which is a good lens, but the STM isn't fast enough for wildlife. I have taken some birds in flight photos with the 18-135 USM, which is a short focal length for wildlife, but I can use it in a pinch. The 15-85 was too short for "in a pinch" wildlife photos, and the 55-250 STM would have to "wake up" to be used for action shots, that I sometimes missed. I like the 18-135 USM.Read full review
