BalasHapusI used this lens quite a lot before I purchased a Canon 400mm prime lens. Although the Opteka lens is somewhat soft and has some chromatic abberation, the images are quite good if the subject has good contrast. I've used this lens with a 1.4X tele extender as well. The resolving power at 1200mm is about 85-90% that of the Canon 400mm used with a 3X tele extender(giving the same 1200mm). I used a test chart similar to the ISO12233 chart to check the resolving power. Where the Canon shines is that it has next to no color shifts in the shadows or on the edges of images. Small black areas will go deep blue and small bright areas (like an egret against a dark background) will have a litttle blue edge on one side and orange edge on the other with the Opteka, but this not normally noticeable unless the image is blown up. Normal subjects will not usually show the chromatic abberation, except on the edges of an image WHEN BLOWN UP.
The focusing on the Opteka is CRITICAL and gets...
BalasHapusIf considering this lense, it is important to be realistic. You can't by a high quality telephoto lense of this size for such a low price. For a good lense of this size a couple of zeroes would need to be added to the price. You will also a need substantial tripod and that will be fairly expensive. You will not be able to get by with the 30 dollar ones, so don't fool yourself. Everything on this lense is manuel. If you are using it on a digital camera as I have on a Canon XTi, none of your automatic features will work. You will have to manuelly zoom, manually focus, and you cannot set the apature at all. The longer you extend the lense the more light will be need, of course, and the poorer the quality. The 2X converter that comes with the package is a nice gesture, but it is really obsolete because the picture quality will be so bad that it is not worth using.
Even with all this in mind, the picture quality is my biggest concern. You will be able to zoom in from a far...
BalasHapusI never expected to be able to afford a lens of this power. When I saw it, I figured at the price, how could I go wrong? (Admittedly, lenses are vastly cheaper than when I purchased the best film-camera I could afford--$600--in '94 and a mere 210mm lens cost as much as the camera.) I live in a rural river valley and the minute this lens arrived I tried it out on the distant hills across the river. WOW!! they look like my backyard and the lens found features my eyes haven't seen in 17 years in this house. A tiny speck on a distant hillside I thought for all these years must be an air-quality monitoring station (it was a rectangular shape, not tall) turned out to be an old water tower made of stone, looking like a castle tower (wish I could show it to y'all). I could see the individual stones. My best binoculars didn't show me this. If you can afford the moderate price, are not a professional (if you've read their reviews, you know they like it but find it less than optimal; but...
