  • Sigma 150-500mm f/5-6.3 DG OS HSM APO

    9 out of 10 points and recommended
    good quality and portability. price good. stabilization is very effective. sharpness and tones outstanding
    need good light in order to get quality image

    Have used the lens for some wildlife and sports photography. Been using lens on canon mark III and the results are very good. Was able to compare pictures with a canon 500 f4 used on the same wildlife outing and found the images to be comparable in sharpness and tone but a bit off in color compared to canon. It is much lighter and portable than the canon and has the advantage of zoom. I am happy with it and would buy it again. I enjoy wildlife and sports photography but have never considered spending all the money it would take to get the canon lense. This one is great and i think you would have to do some very close scrutiny to tell the difference in the photograph produced.
    Even though it is smaller than the canon lense, it is still the biggest lense i have by far. It is heavy and will take some getting used to. I am able to shoot very clear photos at 500 with a shutter speed of 200 and perhaps even slower. I took some sample photos to compare image quality with my canon 135l and 70-300 4-5.6. You just cant compare with the 135 but it appeared better than the 70-300 at comparable ranges.
    If you like to take photos from a long ways off, get this lense, you will have fun with it

    this is the lens. it is crisp, fast, and awsome
    none

    i have never been a prime lens fan, just seems to leave you feeling trapped in a single dimension. But this lens changed my mind. I use it to photograph highschool basketball in poor light. You will never be able to beat this lense, believe me, i have tried them all. It is by far the fastest focusing, best bokeh, and lowest light lens you will ever find.

    I have taken some of the coolest photos with this lens on a canon mark III which shoots ten frames per second. if you really want to get the best gym photos that can be taken, use it and enjoy what you will see. I love this lens

  • Tamron 18-250mm f/3.5-6.3 Di II LD Aspherical IF Macro AF

    great little lens for portability and range. good images
    have to lock it in place or it will extend

    we got this lens to take on vacation because of its size and range. it was unbelievable how well it performed. we used in on a 400 xti and the results were outstanding. it is not made for low light or professional quality but it is so much better than a compact camera. my wife used one of those tiny digitals and the pictures were not even close to what i was able to get with this lens. It is really neat. close up to long range, it is a deal

    great lens. very good image quality and is

    I am not sure if i just got a great copy of this lens or if they are all this good. I read some of the other reviews and find myself wondering if they are talking about the same lens.
    I am not a professional photographer but really enjoy taking pictures and have studied it aggressively. this lens is amazing. It is not huge or heavy, it has wonderful sharpness and bokeh, it has IS, and it has a great range. Maybe it focuses a bit slow but i really like it and have used it for over a year.
