Are there any Teleconverters/Extenders which will work with a Canon Rebel EOS T3 and 55-250mm f/4-5.6 lens?
Which Teleconverter is best along with my Nikon AF-S DX Nikkor 18-105 mm F/3.5-5.6G ED VR Zoom Lens for Nikon-D7200?
Is there a speed booster which will let me use an FX lens on a DX camera with wider focal length and aperture?
What is the use of tele converter? Is it possible that it can be used for all lenses or only for the specific lens?
