Has anybody tried using a teleconverter on the front of this, 1.5 or 2x?

All teleconverters add another layer of glass and will distort the photo somewhat. With the 1.5X or the 2X, it won't be as much as the 4X or the 10X, but usually there is a slight curve around the outside of the lens (like a slight fisheye)

I have used a teleconverter on the front of the Sony 50-210 lens, typically at 200mm setting. My TC has a significantly larger diameter front lens, therefore there is no loss of light. It is a 1.7x. Works surprisingly well - on a test target and in the field. Much better than I thought it would. And, you have the benefit of OS in the base 50mm lens. If you decide to purchase one, get a good one = expensive. The cheepos will certainly cause distortion. And yes, these add a few more layers of glass. I really wouldn't go past a 1.7x. It is time for Sony to grind some glass for E-mounts that goes to 300, even 400mm. I have used a teleconverter on the front of the Sony 50-210 lens, typically at 200mm setting.

I have tried some converters. So far none of them has worked. However, I have not tried the model that you specify.

I had no luck. I bought it and got no signal. Even did a continuity test and seems as if there is no connection. Good luck but I think this is a novelty. No actual way to convert technology.

I do not know. The Cross website only shows two converters and should list what they work with.

I use it off the air from a digital antenna and it works directly without a converter.

No unfortunately but you can find converters for less then 2.50 on Amazon I believe

will a tamron 2x AF teleconverter work this a Tamron 28X300mm Aspherical XR Di Lense and will I gain anything with it. Thanks Steve

I lost so much with this adaptor I quit useing it. It is like a 1.4 teleconverter. Had to unscrew the lens a few turns to get a focus. In my opinion not worth useing. However the adaptor to use the old style nikor film lenses on the cannon digital body works great. You can get these at a good price and they work well. The Konica lenses just don't match well to the optics in the camera in my opinion

Not very likely. The teleconverter was designed for very long lenses and zoom lenses Your 18/3mm me lens' back element must be fairly recessed from the back of your lens for the teleconverter to work, since the teleconverter's front element protrudes into the back assembly of the lens it is tele-converting. If you look at the larger telephoto lenses and even the 105mm macro lens, they have major recesses at the back of their overall lens assembly. Most lenses, however, have flush assembly of elements with the back of the lens. In such cases, these teleconverters cannot even physically be connected to most lenses. Not very likely.

For the system I worked with, no -- I could not. I was able to place the converter behind the screen. I had received an adapter before, and broke the socket the wire plugged into because I tried to force it into the inverter position.

It doesn't convert actually, just passes on the right and left stero channels that are already a part of 5.1. Center, rear right, and rear left just combined in two channels, right and left only. Sounds good like any stereo sound.

Mine works fine for digital channels. You just use the "dash" to represent the decimal point. So "5.1" would be keyed in as "5-1".

No. Acording to my husband, the size of the receiver is too small. Doubling up will not work

I also have the canon 55-250mm and was shopping for a Kenko Teleconverter. Am I understanding correctly, that if I don't mind manually focusing, it still might work?

Yes it should work fine. I have the same setup on my D7100 and the results are great. Slightly more difficult to focus on small distant objects with the teleconverter attached.

You need EF mount lenses. EF-S mount lenses will not fit this teleconverter. In general, teleconverters are a bad idea unless you use them with very high quality lenses. The converter will magnify any flaws the lens already has. It would be more cost effective to buy a longer prime lens than trying to use a teleconverter on any lens with a maximium focal length less than 100mm. You would also be better off just cropping your shots from a telephoto lens that has a maximum aperture narrower than f/2.8 or f/4. Since any 2X converter doubles the effective focal length, it also increases the maximum aperture by two stops. An f/4 lens becomes an f/8 lens. An f/5.6 lens becomes an f/11 lens and so on. An inexpensive telephoto lens such as a 70-300mm f/4-5.6 becomes an effective 140-600 f/8-11. Most Canon bodies disable auto focus any time a lens or lens/converter combo with maximum aperture narrower then f/5.6 is mounted. The 1D series wil allow auto focus to function up to f/8.

Yes, it depends on the source. If the source can read the format and send the digital via optical, the D/A converter will work.
