A telephoto lens can be used for more than simply to magnify distant objects and are perfect for getting you directly into the center of sports activity, a significant benefit of enabling you to zoom in or out to obtain the exact framing you want, which can be especially useful considering that in lots of of the scenarios in which you'd use one you might not have the ability to freely move around.
The Raynox conversion lens DCR increases the focal distance by 2. Telephoto lenses have longer focal lengths and smaller angles of view therefore they make subjects in the distance appear closer and larger.
This telephoto converter lens offers an additional approach if you would like to photograph subjects, connecting the Raynox Telephoto Convertor Lens DCR Pro 2. When it happened inside the lens, keep the lens in a dry area till the dew disappear before using.
Repeating such may leave dirt spot - mildew and affect the image. At our owned manufacturing subsidiary, every stage of production is rigorously checked and tested so that the lens elements compensate effectively for astigmatism, distortion and spherical aberration Nikon Z9 production sample gallery.

And for best results on certain types of images some post processing is essential. More on this later The following two examples were taken using a Panasonic GX7 camera fitted with the Raynox attached to the Olympus Mk2 lens, which was then used at various focal length combinations as specified on the images. Conclusion: I have always thought that the Olympus Mk2 was a terrific bargain, whose price belies its optical quality. Even so I did not expect it to be good enough to work with the Raynox attached, but how wrong I was.
This combination provided terrific reach and accurate focus, thus enabling me to capture small birds in far away branches with very acceptable results. The combination isn't perfect, but used correctly in the right circumstances it is able to produce more than acceptable images.
The following set of images were from one quick snap of our old satellite dish, taken the very first time I fitted the Raynox to an M43 lens my Olympus Mk2 to see if it would work at all. And the result provides a good introduction to Chromatic Aberration CA in the system. I can not remember if at that time the Panasonic cameras were programmed to remove CA from Olympus lenses using firmware, but in my experience the Olympus lenses always seem to perform very well in this respect even without any extra software processing.
Once again Chromatic Aberration can be a problem and ideally needs to be processed out as shown above, but it is a price worth paying if it allows the user to get images that would otherwise be out of reach. One other small point of note to bare in mind is that this 2. The Olympus Mk2 lens quality at full zoom is absolutely fine with the converter at F7.
But with this long reach the depth of focus is very small unless the lens is stopped down, which is why I shot these photos at F8. Well this was the big test, because as far as I am aware there is currently no other way to achieve this amount of long zoom reach from an M43 lens setup that will still autofocus fast and even in poor light.
With the potential of a full frame equivalent focal range of 1,mm on tap, this was just far too tempting not to at least try. But would it be any good? The Panasonic and Raynox Pro is not a terrific combination for general usage, and it can be very difficult to process the resulting image to achieve a useful gain.
But as it is currently the only game it town if you need a huge amount of magnification that will autofocus, let us look more closely to see the pros and cons and if we can gain a worthwhile improvement over using just the by itself Note: All photos on this review page are handheld, even those at FF equivalent of 1,mm!!!
Birds in poor light in a very strong wind is definitely not the best conditions for scientific testing of lenses, especially as they don't sit still either. However these weather conditions are typical in the UK and birding is a typical usage for this type of setup. So as this gull did at least stay on the log being blown around for long enough for me to fit the Raynox teleconverter and try lots of focal lengths, below I present the results Example A and B above does show quite clearly that even with small zoom increases, more fine feather detail can be extracted than when the Panasonic is used by itself, but detail isn't everything and colour casts and CA are already starting to appear.
These aberrations are fairly easily to control at this level of zoom during image processing. The following examples - some of which are OOC out of the camera and others are LR6 processed, - show how things progress when the zoom level on the is increased with the Raynox pro attached. Please be aware that the gull did move between shots and its feathers were blowing around, so a true scientific comparison is out of the question.
But at least you will be able to make some judgements when examining the full size crops. Take note of the purple fringing worsening with zoom level around the beak and also colour tinge in the head feathers on the OOC jpg images. Also on the water behind the gull in the OOC images you may notice that there are greenish streaks appearing with increased zoom level and in certain circumstance this type of CA Lo-CA can be much harder to process out.
Wind blowing the feathers and the gulls head and body moving position from shot to shot unfortunately changed the shadows which enhanced feather detail, thus accurate analysis is difficult. But I think it is fair to say that despite the reduced contrast in the teleconverted images, improvements are there to be gained quite easily and with very little work especially when shooting with less than maximum zoom.
At these ultra-long zoom lengths many factors affect image quality, not the least camera movement. These were taken handheld sitting down using a Panasonic GX7 which does not support the Dual IS feature of the lens. However in my opinion the camera did an excellent job. And no this type of CA can not be programmed out or corrected in software, Lo-CA arises when the light rays from objects in front of and behind the focal plane are not corrected optically, which unfortunately means that objects behind tend to have a coloured glow around them and objects in front have an opposite coloured glow around them.
The actual Lo-CA colours that appear front and back varies with different lenses depending on which colours the lens designers have optically corrected for. See below for an absolutely horrid example
