Don't understand the 1.6 factor (10-22mm EF-S or 17-40mm EF L) Am I understanding the 1.6 factor (on my camera) correctly?

Multiplying the 17-40mm EF L by 1.6x = 27-65mm equivalent focal length. ALL lenses will be multiplied by 1.6x on your camera, regardless of whether they are L glass or not, because you are not using a full frame (1x) camera. But if you EVER plan on getting a full frame camera, keep in mind the EF-S lenses will not work. Though they're pretty easy to unload on ebay. If you don't plan on getting a full frame, this is the way to go: 17-55mm f/2.8 IS USM.

I do not have this problem. Some say it works above 4, but it works on my lens, which goes all the way to 1.8. I don't know why some people experience this, though.

The current kit lens at 18-55mm is wide enough vs. the EF 17-40. Basically you have to ask yourself one major question. Do you plan on going to a full frame camera in the future? If so, then I would consider the EF 17-40 . On the other hand, if you plan on sticking to 1.6X factor cameras, then go with the EF-S 10-22 (16-35mm equivilant)

I have the exact same question. Please do post your findings. I am confused too. Apparently 18-200 is supposed to have larger zoom but I want to make sure that the quality of 18-200 matches to 18-135 at the least upto 135 mm. If so i will go with 18-200 for sure.

Hi,Seems to match.in some extremely wide angle lenses ultra thin filter is used, as far as I know it is not required for 24 mm.I use it on canon 18-200 (cropped sensor).Thanks.Guy

Hi, A. You need to look at your lens to determine the filter diameter. There should be a circle with a line through it, followed by the corresponding size in millimeters.I believe that you are referring to the Canon EF 50mm f1.4 USM (http://www.dpreview.com/lensreviews/canon_50_1p4_c16/). If so, the filter size you need is 58mm. I hope this helps.

The number in MM represents the diameter of the filter - the size of it. Make sure you get the right size or else it will not fit on your cameras lens. You can find the filter mount diameter on the lens itself.

Hi Joe, David is right, The EF-s lenses can be made cheaper, the reasoning is they don't have to worry about the quality covering a Fixed Focal sensor.

I have both this 15-85mm lens, and the wonderful EF-S 10-22mm. Since getting the 15-85, I almost never use the 10-22, even though most of my photography is on the wide-angle side of normal. I recommend both lenses, but get the 15-85 first, and you may find, as I did, that it is very adequate all by itself. If you do need extreme wide-angle, however, by all means get the EF-S 10-22mm, which is excellent. Best, get both!

Barry, I have a Cannon 6d and a Cannon 75-300, 1:4-5.6 and the converter works just fine. The manufacturer states that the converter is not compatible with EF-S lenses. I've not used the converter extensively, but I am happy with the few pictures that I have taken. Hope this helps.

Honestly unless you are making good money off of it go with the 28mm 1.8 it is fantastic. The 24mm is exceptional but 9 times out of ten you will have the same image for 3x the price and twice the weight/size.

you want the 18-270 for a 1.6 crop camera...anyway that's what I'd recommend. I have an old 28-300 for a 1.6 Canon beautiful lens but no VC I don't know if they make this anymore but I took a lot of award winning shots with it email me if your interested :-)

This represents approximately 1/2 stop of light. That may not sound like much but in low light it can make a difference. Also, Nikon doesn't make a 24mm 1.8. the closest is a 28mm 1.8 which is obviously a different focal length. It is a very good lens however. If you don't need the 1.4 and 28mm is an acceptable focal length then go for that as it is much cheaper.

Only the EF version lenses are compatible with the 6d, the EF-S lenses are not. When I moved from my 7D I sold off my EF-S lenses due to this incompatibility.

Nope. The "S" in "EF-S" tells you it's for APSC cameras only not full frame. It's for SL-1, The Rebels, 7D, and the XXd series like the 70D. The STM version of this lens is very nice, quite sharp. Its silent operation is what you want for video.

Sorry Keith and Kenneth, you are both incorrect, I have the S1 in front of me and there clearly are threads on the front of the lens, in fact the furnished lens cap snaps into those threads. Fuji just wants us to buy their expensive adapter requiring an expensive 72mm filter. Measuring the threads they appear to be 53.5 or 54mm I don't have a precision caliper but a 52mm is slightly too small and a 55mm is slightly too large. 53.5mm & 54mm adapters are rare so I am convinced Fuji deliberately did this to discourage one from just buying a regular filter.

Hi Technology Guy,I liked you responses to the questions asked by fellow buyers. You may find me moron asking this but I searched quite a bit on google but did not get any definite answer. Could you help me decide if it is wise to buy T3i (600D) with "Canon EF-S 55-250mm f/4-5.6 IS Telephoto Zoom Lens" and do not buy "EF-S 18-55mm f/3.5-5.6 IS Lens"? OR if I need to have both lenses to start with. Thanks in advance.
