When I first used this lens I was a rank amateur so I had no idea what I was doing. Now that I have advanced beyond my kit lenses, the limitations of this lens are glaringly apparent. My major problem with is the fact that you cant use a polarizer or split ND filter with it due to the external focusing mechanism.

I got this lense the same time I got my camera. And I have to say, I'm pretty impressed. I wouldn't recommend this to a professional. But for a beginner or a intermediate photographer it's a perfect fit. It's a great lens and I would recommend this to anyone who would like a medium duty lens.

Got this extra with my rebel t3 kit, my first foray away from the point and shoot. So far so good. While I'm not a professional, I take the occasional shots whenever something catches my eye. As I've been playing with the lenses, I've noticed that if you follow the parameters of the lens, it will give you good to great results. Tried to take a picture of the big and little dipper, guess it wasn't enough light as the camera just wouldn't focus. On some subjects, it just keeps focusing, found out a couple of steps taken backward can alleviate that issue. Overall, so far, its a good lens and can give you great shots. Being that it doesn't have IS, if you zoom to the max, you'll get nothing but blur so invest in a tripod. Anything closer and the focus is great.

For starters this is not a lens for professionals and I'm not one anyway so..., knowing that this is a great lens. It has the features you'll need to take it into the field and get some really good photos under your belt while getting use to the handling and functions of a telephoto lens. After you master this one and chose to use your camera rather then park it in the closet you may end up buying the next level up but for starting out or even for a an everyday knock around lens this one is perfect and can handle some abuse with no trouble. For the cost you really can't beat it. Overall the images will be some you can take a level of pride in. I have taken some longer shots (around 50 to 70 yards) of birds which came out pretty darn good. After printing them I was fairly satified with it and I'm happy enough with it to say "I would" buy it again for the price. After all the cost is nothing compared to other high end lens's and it's a little toughy that will not make you worry to take it in the woods or the city and get a few bumps, it can handle it. If you buy one for non-professional work you'll have some really neat photos that people will admire including you.

Once I got to understand the lens, it worked very well. For fast focus I do my best manually, spending less than a second. At the same time I can adjust the camera settings w/ my other hand. Then I flip the AF switch on, 1/2 press shutter and away I go. If the shot is far away or the aperture is higher than 11, I can just turn the AF off again. The Subject can move a fair distance without loosing focus. This is a great lens for the price. Be warned, many shots will only work with a tripod. I have the best results if the Sun or its reflections are not in the front of the lens. I would recommend using a lens shade and a polarizer when shooting outdoors. P.S. If the user is not fast, the camera never will be, you must conceive of what might come next. Always be prepared.

ive had this lens for quite some time now and use it mostly for shooting wildlife. for a first telephoto lens its great to practice with, you really can get good sharp images with this product. one thing however, is the auto-focus. i have missed plenty of great shots because of how slow and sometimes inaccurate the lens is. i would recommend using the manual focus and learn to focus accurately and quickly. now this is no pro lens unlike the canon L lenses that ill soon be upgrading to. its also important to note that this lens should not be used in extreme weather conditions as dust and water are easily accessible to the interior of the lens. if your looking for a manageable low priced telephoto this is something you might consider. i love canon products but if you want to really get serious into photography and telephoto zoom, their L series lenses are the only way to go.

Not much to say... it's average lens all-around. Not a bad lens, but not really good. It has great range, but you will need a tripod, for sure. Images are nice, but not perfect. Great lens for beginners because of price. No USM, and no IS make it pretty plain. I bought a 55-250mm IS lens to replace this one. If I know I'm going somewhere where I'll need the extra zoom, and I plan on bringing a tripod, I will bring this one out of the closet for a bit. If you're looking to buy a telephoto zoom, save up for a couple more months and get the 55-250mm IS lens. For what it's worth, you absolutely can't argue with the value.

Have used this lens for Aviation photography for almost 2 years now, i understand this is a starter lens, usually on a starter camera, (T7) but this lens definitely has some problems. Zooming past 150-200 mm cooks the sharpness, but after mastering the lens, it can be a manageable loose cannon, getting sharper images after figuring out camera settings and prime focal lengths. Going from this lens to the EF 100-400, is a whole different experience. The 75-300 is a decent starter lens and i won't discredit it, it has got me some of my best photos, (somehow) but in conclusion, there are definitely better lenses out there. Cheers.

I BOUGHT THIS LENS TO PUT ON MY OLD CANON EOS REBEL TO TAKE WITH ME WHILE DRIVING AROUND. I WASN'T SURE IT WOULD LIVE UP MY EXPECTATIONS, BUT WAS WILLING TO SETTLE FOR A LITTLE LESS. BOY, WAS I SUIRPRISED. IT HAS GOOD QUALITY, IS WELL MADE, AND TAKES BEAUTIFUL PICTURES FOR REAL. THE AUTO FOCUS IS A LITTLE SLOW, BUT WHEN IT LOCKES IN, YOU HAVE A BEAUTIFUL PICTURE. THE AUTO FOCUS IS A LITTLE STIFF, BUT I THINK IT WILL NEVER HAVE ANY LENS CREEP. I CARANKED IT UP TO 300MM AND CAUGHT A HAWK IN FLIGHT. IT TOOK ON OF THE MOST BEAUTIFUL PICTURES EVER. IF YOU LEARN TO USE THE LENS PROPERLY, LIKE EVERYTING ELSE, YOU WILL FIND NO FAULT WITH IT. I HAVE A 70-300 IS USM, AND IT TOO IS KING OF THE ROAD. I HOPE CANON STAYS ON THE RIGHT PATH, AS RIGHT NOW THEY PRODUCE THE BEST LENS FOR THE MONEY, PERIOD.

This is a great lense! I just bought it with my first DSLR in a package. i got the Rebel XS. I love the lense. I gave it four stars for features because it is not IS. I dont think that this is a big deal considering the price. I have been able to obtain some great pictures with it and i have no complaints. I have had it for about a month or so and have used it a lot. I have heard complaints about the autofocus but it is plenty fast enough for me, even fast enough to keep up with my 1.5 year old yellow lab puppy!
