    Helder MT-1758 reviews

    MT-1758 58mm HD 1.7x Telephoto Conversion Lens is rated 2.3 out of 5 by 3.
    Rated 2 out of 5 by from Heavy and Vignettes Like most people that take photographs I was hoping to extend the reach of my lens. I bought the 1.7x Telephoto Conversion kit for my 55-300mm lens to get out to 510mm without paying the cost of a 500mm lens. The first thing to understand is this thing is heavy. After screwing the conversion lens in place the autofocus slowed way down on my Nikon lens. Not only that but it also felt as if the gearing was being strained in order to extend the lens all the way out. I took a few test shots with the lens and had vignette with the lens all the way out to 510mm. The lens cover is rubber and slips over the lens and cannot be used with a lens hood on. With all the issues I did not feel I would be able to use this conversion lens and returned it. I did give it two stars because the construction of the lens appears good and this might work well on a camcorder.

    Rated 3 out of 5 by from Best for recording minimal movement The telephoto lens work well but the issue I had was focusing when the picture got closer. It would recorded with the lens figure. I record my sons football game so when the plays drew near I would lose focus. Yet for the long distance I got a good picture. Estimate 50 yards out or more.

    Rated 2 out of 5 by from too much vignette showing in zoom i tried to use this on a canon hg10 video camera to give me more zoom. however, with this lens the vignette area is huge. with the 1.7 converter you really can only use the last .3 of the 1.7 due to the vignette ring being in the picture for so much of the zoom. not good.
