Why does this lens say it is 18-35 when clearly this is a 27-52 lens on an APS-C sensor(this is not wide by any standards).

I agree it not a super/ ultra wide. I'm not sure that is it's best use anyways. It is as wide as I could find at f/1.8 at 18mm (27mm relative) at this price point with near perfect clarity. I use mine for indoor group shots and can tell you it is wide enough for that and the pictures are amazing with this glass. If you really want wide angle then I would consider prime lens.

Technically it is an 18-35. The camera crop sensor changes the perspective not the actual lens.

I'm sorry, I am using a Canon 7D. I know of 2 friends using it on other bodies and we are all getting great shots at full crop. Sorry I can't be more specific.

Well there are two different "kit" lenses the 18-55 and the 18-135. Now the 18-55 is not a "bad" lens but most people skip that and buy either a different Sony lens,a Sigma or Tamron lens. Pretty much because the 18-55 is a "ok" start out lens but not even a year down the road you will most likely want to upgrade. Now the 18-135 alot of people seem to be happy with, it is more money, but it will probably save your money in the long run. But remember this item is BODY ONLY , so no lens came with this one!!! Make sure you find one with the lens included if that's the route you want to go! Well there are two different "kit" lenses the 18-55 and the 18-135.

I returned this lens and the camera that used it. I suppose it's more or less the equivalent of a 35mm in full frame, a bit of a wide angle.

The L indicates it comes with the newer 16-50 power zoom lens rather than the older style 18-55 lens. I am not sure if the letter was chosen at random or not.

That is a very subjective question as I have seen plenty of wider, and less wide lenses be used for the night sky. If you are using a full frame camera, 35 can be considered on the wide end. If on an APS-C camera I would not consider it wide, however I have seen some great night sky shots that are not wide. The aperture on this lens will make it conducive to shooting the night sky so that will not be an issue. What you can do is if you go to Flickr, search night sky and look at images that you like. If you click on them they will often tell you what lens is being used which may help you decide. Other wider options from Samyang are their 14mm 2.8, and 24mm 1.4 lenses. Hope that helps!

A little late for an answer for these folks, but in-case anyone else runs across this question and wants to know...The difference is that most brands that use APS-C sensors have a crop factor of 1.5x , however Canon has a crop factor of 1.6x.This lens was designed to give 180° on an APS-C sensor with a crop factor of 1.5x. This is why on Canon you only get 167°.Mounting a Nikon lens (via an adapter) to the Canon camera will not change the crop factor of the sensor, so the FOV will still be 167°.

Harry: the sensor in the 645D is not 4.5x6 cm but rather approximately the size of two full frame sensor stacked on top of each other. Actually the 55mm lens is not "normal" in the sense that 50mm lens is normal on 35mm film camera, but rather about a 35-40mm equivalent in 35mm terms.

The 18-55mm SAM II is made for APS-C sensors, so you will get a sensor crop (APS-C area on the full frame A7 at the correct focal length) or a lot of vignetting if you use the whole sensor. The 55-200mm should behave the same way. The 50mm 1.8 is made for APS-C. The 1.4 is made for full frame and will send light to the whole sensor.

Yes, it is. The focal length and aperture value cannot be mathematically separated, and must both be multiplied by 1.53.

This lens has a comparable focal length of 16 - 28.8mm in a 35mm equivalent. If you have any further questions or concerns, please don't hesitate to contact our sales department at 800-991-3350 EST. We thank you for your time and consideration!

If you take a look at the front of any lens you will see numbers indicating the millimeters and the F range, these numbers have nothing to do with the size of the filters the lens will accept. Usually there is a separate number set apart from the lens type numbers that indicates the proper size filter to purchase. On my lens I see a O with a forward slash through it (sorry I don't know how to type that symbol) followed by the number 55, so I use a 55 mm filter.

I'm starting to think Sony has something to do with this. It is my understanding that Sony owns a piece of Tamron, and Tamron makes some lenses for Sony (55-200 and 18-250). It may be that Sony does not want this lens to compete with it's 70-300 G since the Tamron is nearly half the price. I was looking for this lens to replace the 70-300G, after two bad copies I got rid of it, it's not worth $800.

On a Canon it would give equivalent field of view at x1.6, so it is probably about the same field of view as a 36 mm lens on a crop sensor.

There is a 58 & a 62. What filter size does the lens require? It sould say on the lens. Take that number and compare with the list.

Only on full frame format it is true 11-16mm with vignettes on wider opening. On your camera it is like 17.6 to 25.6, but with no vignettes and very bright and nice (it is 2.8). Of course you know that your 18-55mm kit lens also is in fact like 28.8 to 88 mm. Hope it helps.

This is for a Sony camera with APS-C size senor ... ie NEX Series and others. The crop factor is 1.5. Therefore, while it is 35mm in focal length, the view through the lens is equivalent to 52.5mm (35 x 1.5 = 52.5) lens of a full frame DSLR.

I have one of these but it is a Sony E Mount. The lens was designed for the Alpha series which is a cropped sensor. APS-C. on a micro 4/3 this is probably closer to a 30 to 35 mm focal length one other thing you need to look out for the picture associated with this lens notice that the focus ring is smooth. If you get one that has a textured focus ring (ribs) you are getting the old version of the lens. The picture here depicts this as the new version which is classed as a art lens hence the little A logo on the barrel.
