Bower 650-1300mm f/8.0-16.0 overview

  • 1Description

This extreme 650-1300mm f/8-16 Manual Focus Lens from Bower is an economical way to achieve some ultra-telephoto photography, all the way up to 1300mm.  This is a T-mount lens, which means that aperture is not communicated to or controlled by the camera body, and in this particular configuration is delivered with a T-mount which fits any Olympus OM system camera.

It has only one effective aperture at any focal length, which varies from f/8.0 at 650mm to f/16.0 at 1300mm.  That's not much of a hinderance, however, as you'd likely use this lens at its relatively small maximum aperture in any case.  Only use this lens in fully manual mode or in aperture-priority autoexposure mode if your camera has it.

This lens requires bright light and high-ISO film to get a fast shutter speed, and needs a sturdy tripod or monopod, but can deliver very sharp results if used properly.

    This extreme 650-1300mm f/8-16 Manual Focus Lens from Bower is an economical way to achieve some ultra-telephoto photography, all the way up to 1300mm.  This is a T-mount lens, which means that aperture is not communicated to or controlled by the camera body, and as such must be used only in aperture-priority auto-exposure mode (if your camera has it) or in the manual exposure mode.  There are T-mounts available for every modern DSLR system as well as for older film cameras and even C-mount cameras.

    It will work on both "full frame" digital cameras as well as the smaller-format APS-C (15 x 22mm) cameras, but has only one effective aperture at any focal length, which varies from f/8 at 650mm to f/16 at 1300mm.  That's not much of a hindrance, however, as you'd likely use this lens at its relatively small maximum aperture in any case.

    This lens requires bright light and a high ISO setting on the camera to get a fast shutter speed (or fast film in a film camera), and needs a sturdy tripod or monopod, but can deliver very sharp results if used properly.

    The lens features an incredible zoom range.
    This lens has a two-touch zoom/focusing system. There is a push-pull ring for zooming, and another ring for focusing.
    Multi-coated elements reduce flare and increase light transmission.
    The white lens barrel helps reduce heat buildup.
    The aperture is fixed-position, but only varies based on focal length.
    It has a deep lens shade with matted, dark internal coloring.
    The lens has a tripod mount upon its lens barrel.

Bower 650-1300mm f/8.0-16.0 reviews

650-1300mm f/8-16 Manual Focus T-Mount Lens is rated 4.1 out of 5 by 40.
Rated 4 out of 5 by from More Than I Expected I was a little leery when I first purchased this lens. Once in use, however, I was more than satisfied with the results. For the low price paid ($) for the lens, polarizing filter and UV filter, it was worth the price. Pictures attached were taken hand held at about 1000mm on my Canon 5D MK II. It's full manual mode only.When the barrel is extended to the 1300 mm point, there is a little bit of deflection, but mostly disappears when you lock the barrel. The lens bag isn't too sturdy (zipper seems to be separating) and the bag is narrow, so that the lens hood falls off while pulling the lens from the bag.

Rated 4 out of 5 by from Great long range lens I purchased this mainly for wildlife shots but was amazed when I used it to shoot the full moon three nights after I received it in the mail. The craters and ridges of the moon were awesome. This is definitely not a walk around lens but when you want to get close it can do it, a tripod is a must, not a cheap one, a good sturdy one.

Rated 5 out of 5 by from I love this lens ! Not the sharpest ,but great and easy tu use. I live on the 8th floor in front of the beach in Miami, I shoot birds and people on the beach , with my long experience I can shoot handheld in daylight ,not easy.At night is very hard to focus . but with a strong vivitar flash and flash extender at night I got good pictures . imagine 8 floor and 200 feet of beach is a very good reach for this lens.Sony SLT35 .only one problem is that when the lens is on the tripod and fully extended the weight of the camera makes the last barrel droop a little bit and slightly misaligned with the rest of the lens.......................Thanks BH for carrying great products like these, I've been a customer since 1992

Rated 3 out of 5 by from Long range Zoom this lens cost me around $300 ... and price at this price to hope for crystal sharp images at 650-1300mm was out of question to begin with but i realize that if i get focus good enough and with a little bit of post processing the images don't look that bad. You need a good Strong tripod as its heavy and long lens that will cause the camera shake if tripod is not capable of that much weight at a longer leverage,images look blues if we don't adjust for Chromatic Aberration

Rated 4 out of 5 by from Good product, brain power required I have used this lens for over 2 yrs and it still amazes me. I use a Bogen tripod and still have to watch the shake. Sturdy & heavy will keep entire thing from nose diving in to the ground. Mounting ring use is a must! Suggest dedicating a quick release mounting block left on the lens for convenience. You need to have both hands free to do all the manual adjustments & not get in a hurry. take your time. That being said the moon will seem to streak across the view finder. Now for the issues: 1. infinity focus will depend on individual DSLR & the T mount adapter thickness. I didn't get lucky so I modified the T mount,careful grinding! I do not suggest making any modifications to the lens barrel! another option is to locate infinity and mark that point on the barrel with a fine line permanent marker at the tube joint. 2. The focal length nylon lock ring in my unit was installed backwards allowing creep and barrel sag. This is where the simple sturdy construction is a blessing. I had no problem disassembling this portion of the tube and reversing the tapered nylon ring. Made all the difference in the world. 3. Lens is not fog, water or dust proof. Will eventually require service. Constant humidity will grow stuff inside. Good thing is simple sturdy construction makes this no big deal for those mechanically inclined with basic understanding of cleaning lenses. Even with these ISSUES I love this lens. I don't miss spending 10 or 20 Gs for my favorite brand.I gave it 4 stars only because of the issues listed above. Otherwise it would be a 5 STAR VALUE!!

Rated 5 out of 5 by from Good quality product for the price. Purchase this as a lens to drag around the country side leaving my expensive lens back at the studio. I have found that this lens meets or exceeds my needs. I wouldn't recommend this lens for the novice you will need good understanding of f/stops and focal length to get the photos you really want to capture.

Rated 5 out of 5 by from Better than expected I have had this lens for a couple weeks now and am very happy with it. The photos I am getting are a lot clearer than I expected to get from a $300 lens. I am using the lens to photograph a nest of baby Red Tailed Hawks and can not get any closer than about 175 feet.

Rated 3 out of 5 by from Cheap, but decent for the price I got the lens for taking a few pictures in the open sea of boats and other objects far away. With my Rebel I got some awesome pictures, the F-16 at 1300mm is fine and very usable in full sun and produces images with detail far above what you can pick up with your own eyes. The downsides are severe chromatic aberration, high weight, and the manual zoom is much more problematic than the manual focus (unlock and pull is a slow and cumbersome way of zooming), at the high zooms the camera clearly is a little off the plane of the lens (it bends the lens at the zoom point). The vignetting in the viewfinder of my rebel at 1300mm is also at the point that it becomes difficult to spot things, this however doesn't show up at all in the final picture. Overall, for the price, it's a good buy, not the best pictures, but it can be very useful as long as you have a sturdy tripod.
