How far can this lens go with regards to zoom capability. What does 45-175 mm. mean converted to zoom #? Thanks

I'm not sure what a zoom # is. It is very nearly a 4x optical zoom ( not digital ). It will give you a field of view ( based on the 35mm film camera or FF field of view ) of 90mm to 350mm due to the m4/3 sensor size which roughly has a 2X crop factor (while a Canon 6D or Nikon 7100 has a 1.6X crop factor).

45-175mm is equivalent to 90-350mm since the sensor is half the size of a full frame. Therefore 12-35mm is 24-70mm or 100-300 is 200-600mm full frameGood luck

If you mean in 35mm terms, then it would be like a 90 mm to 350 mm given that the sensor format is half the size of 35 mm. If you mean zoom factor, then it would be 175mm/25mm = 7X since the normal lens for this format would be 25 mm. 7X zoom doesn't sound like much in this day of mega-zoom point-and-shoots, but because of the resolution available, even under low light with the ISO bumped up, you can crop quite aggressively and still have a very nice image. I shot birds in deep shade the Amazon at ISO 6400, cropped, and you would never guess it.

I have gotten great detail using this lens. However, when I'm taking portraits I prefer my 16 -- 135 mm lens. Nontheless, I think that this lens does very well at the lower limit of 70mm.

It will not go to 500MM zoom, you have to use it on manual setting. This lens is more trouble then it is worth.

do you mean non-AF ? just fine as long as you can focus :). any 1.4 or 2x converter will let you know if the lens you have is good or not since its enlarging the image. the 1.4x is pretty gentile and any decent lens should be ok if stopped down 2-3 stops from wide open.

The 17-85 is a nice lens unless you got a poor copy - it has more reach & was designed for the crop cameras. The 17-40 is a superlative lens with astounding deep, rich color and photo quality. If you want longer, you won't be happy but if you can work with this range it is great!

For the sake of a common frame of reference most companies prefer to advertise the focal length of the lens converted to the 35mm equivalent. Thus, even though the G1 X is truly a 15.1 to 60.4mm zoom for its particular sensor size, that converts to the 35mm equivalent of a 28mm to 112mm zoom.

I've always considered lenses of less than 35 mm "wide-angle". It's a matter of degree, but I would consider 28mm a wide angle lens. Since around 50mm is "standard" focal length, it is quite a bit wider than that.

BTW, that 135mm/3.5 is a great lens. With the 70D's 3x sensor crop zoom, you have a de facto 215mm & 648mm lens in one compact package. I love my 135mm.

you will see some distortion at the 18mm range but will disappear in at the 25 to 28mm area- sometimes it is rather a nice special effect, depends on the shot. Make sure it is a Canon IS lens for the stabilization. The zoom has a very nice range but you will loose some speed as compared to a simple wide angle lens. It is a great walk around lens to suit needs of a wide range of situations.

This lens for me anyway is fantastic. Love this lens. Nice bokeh. Great quality. Only issue I have is because of the smaller sensor the 50 mm is actually a slight zoom. If I did it again, I would probably look for a quality 35mm lens with the same aperture. I believe I bought this from sunset. Didn't have any issues with them, but that was a while ago already.

yes it'll amaze you how close you can get with this lense. It seemed like I was never able to get close enough to the action with my 28-80.

Which lenses? In any event, the f-stop is printed on the lens, either on the barrel or the ring around the glass at the front. For instance, on my 12-50 mm zoom the f-stop range is 3.5-6.3 and is written "1:3.5-6.3". F-stop is the ratio of the diameter of the lens opening to the focal length, so on a zoom lens the maximum f-stop depends on the focal length the lens is set to. The longer the zoom length (20 mm vs 45 mm for example) the smaller the f-stop. Know that the scale is reverse, the more light a lens passes the closer the f-stop number is to 0. For example f/3.5 passes way more light than f/11. Do an online search for "F-stop" and you should find a reference to a Wikipedia article explaining it. Hope you like the camera as much as I do.

Congrats on the nice lens! I have the 17-85. It's better than my 18-55, but I would love to get the 17-55 someday. Heck, I'd like to get a lot of different lenses someday! But being completely new to dslr, I think what I have now will suffice until I get going.

It is a really nice lens. Though if you want portrait or medium telephoto, the 135 f/2 or the 70-200 f/2.8 are both fantastic as well, and maybe better suited.

The 18-140mm lens is a very good lens. I did trade mine for a 16-85mm lens that fit my work better. Also I have used the18-200mm lens which is also a very good lens. I don't think you could go wrong with any of these lens. The choice remains on what you want from your lens.

I think that refers to the macro feature. True macro would be 1:1 meaning a one inch object would be one inch on the sensor/film. So this lens would have a one inch object being .36 inches on the sensor. Which is quite good given the sensor size. The zoom is as rated (12-50 with a 2x crop)

I'd put it in the 1.4 group... I love this lens. Tact sharp and can focus up close to your subject.
