Yes and the only loss in image quality will be due to the filter/magnifier as the tube/s only add a few cm of air to the light passage and air doesn't have any effect on light. A lot of DSLR also have a digital teleconverter that you can use in conjunction with your tubes and filters/magnifiers. I have a Sony SLT-a77 and a $130 tamron 70-300 macro zoom and ...


Don't fit your lenses to the extension tubes and then to the camera, unless the manual for the tubes says so. I use a Sony SLT-a77 with extension tubes and the instructions are to fit the tubes to the body first or the TTL and AE may not work. I definitely wouldn't use tubes that have exposed metal inside the tube, like those pictured above. The insides of ...


With a tested Minimum Focus Distance (MFD) of 16.81 inches at 270mm and a Maximum Magnification (MM) of 0.26x, or approximately 1:4, you can't really do Macro photography with that lens. And since it is already slow at f/6.3 at 270mm, the minimal gain you would get in terms of MM by adding extension tubes would make the lens too dark to be very useful.


There probably won't be a macro facility to 'activate' - the 'Macro' designation just means the lens can focus very close to your subject. If you are using the lens at the closest range available on the focusing scale (probably using the longer end of the zoom range at the same time) then you can safely claim to be practising macro photography. There is no ...


You can use a smartphone (e.g. Galaxy S5 + PVC piece of pipe or iPhone + Magnifi™) placed directly on the scope (onto the eyepiece section). Result (red blood cells as shown at Aurel Manea's blog):


I have a consumer camcorder which gives 32X optical zoom and after using it for a year I wanted a DSLR which would do the same thing. For a DSLR lens to offer the same zoom range is unheard of and I was disappointed to learn how the DSLR makers aren't making such lenses. I have a 10X zoom lens for my DSLR which all by itself is larger and heavier than the ...


As others have wrote - it is difficult to make lenses that can focus at very different distances. Designer of the lenses have to choose possible distances because it may affect size, weight, complexity and finally cost of the lenses. In fact there are also lenses than can focus at very close distances but CAN'T at far distances. The example is this: Canon ...


It is very possible, and you can even avoid parallax by using a macro rail shifting it parallel to the subject. In this manner you dont rotate the lens around a nodal point.
