Showing 1-10 of 12
Good for the money
19 August 2013
Summary: This lens is a nice tele for beginners. It takes fairly crisp images with proper light. There is no stabilization so low light situations, (even evenings or shaded areas) will require a tripod. The lens is quite heavy but that is to be expected. The build quality is a tad suspect. There is actually several small specs of dust on the inside of the lens.
Great value for price; some caveats on performance

Summary: I bought this lens along with a 28-105mm zoom to get a wide coverage of focal lengths for as little money as possible. At the same time, I wanted to maximize my sharpness at 300mm for bird and astronomy photography. If this is your goal, then this is the perfect lens. It is significantly sharper than the 75-300mm lens at 300mm, while still staying under $300. If saving money is your absolute priority, then go with the 75-300mm.
Conclusion: I need a 300mm lens. What I really want is a 28-300mmISUSML lens. I do most of my photography from the confines of a fairly tight airplane cockpit. I thought that a compact lens such as this 100-300mm would fit the bill. So I bought it. It's going back to the dealer tomorrow. The lens is so light that it's near impossible to hold steady while on a bumpy taxiway or in light turbulance in the air. I really need a heavier lens to help dampen out the bumps.
Pros: price, light weight, ring type zoom.
Cons: too light weight, slow focusing for a usm lens, not very sharp.
Conclusion: This was the second lens I bought (the first was the EF 28-105 f/3.5-4.5 ii) and it served me well while I was learning. Now I've moved on and up to the EF 200 f/2.8 L and the difference is striking. I use my long lenses for high school sports (soccer and baseball). The USM drive in this lens is quite capable of keeping up with sports. The maximum aperature of f/5.6 when extended really hurts though.
Summary: In the telezoom range there's no great offer if you are not able to spend a lot of bucks. I wanted a USM and I had the choice between this one and the 75-300 IS. I'm quiet glad about the optical performance, although there's better to get at the 300mm position, but what especially bithers me on this lens is the AF: s-l-o-o-o-o-w!!! On the other hand, with a digital rebel, it makes a 150-450 zoom, which makes up for all the rest.
Pros: 150-450 zoom with a digital EOS,, solid, compact
Cons: slow AF, hezitating too much., optical performance at 300mm position.
Conclusion: Not a horrible lens. Good Over all zoom. Looses Sharpness and becomes very soft around 210-300 and it even drops off from 100. Ive got some wonderful pictures from this lens though. Light weight is a tremendous factor. Rear Focus is Pretty quick. Does tend to slip when you point it to the ground. Not a bad lens overall. I would recommend this lens for the 70-300 zoom range rite behind the Canon IS 75-300. Another Draw back is the 100 Starting point.
Pros: Light Weight, Compact, Good Travel lens for intermidiate photographers.
Cons: Sharpness Drops off the deep end when you use it from around 210-300mm. I would recommend the product to Beginners through Semi-Advanced Amatures.
Summary: I have had this lens for more than 4 years and shoot primarily head portraits of family and friends and animals at the outdoor zoo. At the time I bought the lens, it was highly rated in the literature. Between 100-200mm, the lens performs very well indeed. Enlargements of up to 8X12 look good. More than 200mm, the images become soft. Handholding at 300mm is not advisable unless with fast film or its a bright day. The zoom creep, as has been mentioned by others, is bad.
Pros: Good between 100-200mm. Fairly rugged.
Cons: Zoom creep. Poor image quality at 200mm to 300mm.
Excerpt: Я хочу опровергнуть заявление бесполезности этого объектива. Дело в том, что фокусировка минимальная составляет 1,5м, это для всех 70-300 объективов. Так вот, полезность 70мм на этом растоянии никакая. Получается что с этого растояния, на 70мм, вы делаете поясной портрет. Так вот, имея 28-105, такой портрет спокойно делается и с более меньшего растояния и удобней, чуть ближе, чуть дальше. Телевик же достаешь во первых: когда далеко (фотоохота), во вторых: для портретов.
Excerpt: Я взял этот объектив к камере Canon D30, очень доволен. Увы, 100-400 L я вынужден был продать, но в принципе 100-300 меня устраивает. Очень хороший репортажный объектив. На 250 мм фокусного дает картинку, вполне разгоняемую до А4 (на мой вкус). Фотографии с него успешно продаются.
Pros: Быстрый автофокус, возможность ручной фокусировки при работающем АФ, солидная конструкция, хорошее качество картинки
