Yes. You can do things with a wide angle that can't be done with photo stitching. This photograph could not have been stitched; whilst I had time to take a few shots, I would never have had the chance to stitch it together. Also the wide angle has a distortion effect, and this can be used for its specific composition effect and to draw attention to ...

I don't understand why anyone would buy it Optical quality, build quality, and overall durability. The EF 17-40mm f/4L USM is an "L series" lens -- essentially professional grade, while the EF-S 18-55mm f/3.5-5.6 is a consumer grade "kit" lens. L lenses are made with better materials, better designs, and more features. They're weather sealed to keep out ...

When a field of view is described as 120°, that refers to the total angle. So, 60° to the left of center and 60° to the right. Most camera lenses show a very restricted subset of the field of view perceived by the human eye and vision system. It is probably the case that the system is measured across the diagonal from corner-to-corner of a rectangle, ...

Great question. A little over a year ago, I bought an ultra-wide (10-24mm f/3.5) lens with an eye toward landscape shots and quickly saw that generally, I can stitch images taken on a longer lens and produce more satisfactory panoramas. So, as you ask, what's the point of an ultra-wide? Well, to answer it, the best approach is probably to discuss what an ...

Strictly speaking, image stabilization (IS) is not a necessary feature for any lens. For the vast majority of the history of photography IS as we refer to it did not exist. Plenty of remarkable photos were taken in spite of the lack of IS. The ultimate method for camera/lens stabilization will always be a stable tripod with a quality head attached and a way ...

The advice you read is an example of the phrase, "A little knowledge can be a dangerous thing." There are filters known as Variable ND filters that are basically two polarizer filters stacked on top of each other. As the axis of polarization is altered between the two polarizer filters the total amount of light allowed through will vary. If an ND filter is ...

If there is anything moving in the shot, then there isn't a substitute for a good wide angle lens. In addition, the difference in angle of the lens is going to result in a characteristically different feel from multiple shots at a longer focal length than a wide angle lens would have given on it's own unless you use a specially built mount that can rotate ...

It's not so much a defect as a property of wide-angle lenses: they distort things on the sides. This distortion is why they are not recommended for portraiture. Of course, the very same distortion is what gives wide-angle its power, making it great for photographing interiors (making them look larger) or when going for an "artsy" effect.

What would I have to do to take such photos from a 50mm lens of a Dx camera? You can't take those pictures with a 50mm lens and a DX (1.5X APS-C) camera. To fit all of what an 11mm lens will give you you'd have to back up five times as far. But that would change the perspective, or distance relationships between the various parts of the scene. To get those ...

Canon EF-S 10-18 or Tokina 11-16/2.8. :D Sorry. Neither one of these is ideal on a crop body as a landscape lens. The fisheye has too much distortion and would require defishing if you ever wanted a straight horizon anywhere other than the center of the frame. And defishing will cost you the edges of the frame, so it won't be super-super-wide (which is why ...

Distortion caused by a lens's optics would give you barrel distortion (objects appear to bulge outward) or pincushion distortion (squishing inward). The skewed lines you are observing are straight; this is perspective distortion, and is not a problem caused by the lens nor fixable with better optics (you can fix it with a tilt-shift lens, but that's a ...

This is simply where the market is converging to at the moment. The typical kit lens is still 18-55mm on an APS-C sensor but most people find wider angle more useful, so some manufacturers made a few lens that start at 16mm. Olympus still sells many of their entry-level cameras with a 14-42mm which is equivalent to 28mm, while the 18-55mm mentioned earlier ...

First off, although the sellers label it as a wide angle lens, in reality what you are considering purchasing is more properly called a wide angle conversion lens because it screws onto and converts your existing lens to cover a wider field-of-view. In general the products sold in this price range aren't very good, and that is putting it nicely. There are ...

This question already has nice answers. I'll just address one sub-question inside your question. Namely: I can see why this might be the case and that for the most part that it might be undesirable, but is it really that much of a problem? Yes, it can be a problem. Painfully obvious in this photo of mine: Here the reason is not only the wide angle of ...

You would need a step-down adapter, such as this with a 55mm thread into your kit lens, then a 52mm thread for the wide-angle converter. Unfortunately... you will very quickly discover that these wide-angle adapters are not worth the money, however tempting they may appear. I'm certain their entire purpose in life is to teach poor unsuspecting newbie ...

Graduated ND filters are usable with wide angle lenses. They should be big enough to cover the complete field of vision. There are certain wide angle lenses that have a protruding front element that make it difficult to use regular filters (Nikon 14-24 2.8). Polarizer filters are not recommended for wide angle lenses, because the bigger field of view may ...

For distant scenery, you are right you can stitch. Problems: the time to process multiple images. Instead of 50 wide angle shots, you have 150 to stitch together. You'll end up with larger files, so more pixels to work with, but bigger files. Ghosting - clouds, tree limbs, or people are moving may make seams problematic Foreground interest. Most good WA ...

Rather than considering a whole new camera, as the S95 is a rather nice little thing, you could chuck a small tripod in your backpack for these shots. This would allow you to compose you shot with your wife and use the self timer for the photo. Gorillapods are tiny enough to go in your pocket and can grip onto benches, railings, or branches or you could ...

Because "wide", "fast" and "low-priced" don't ever go together. The Canon lenses are low-priced because they're pancake lenses and not particularly wide on the format it was designed for, nor particularly fast (for primes). Similar to the (very old) Nikkor 45/2.8 P. I would suggest looking at 3rd-party f/2.8 17-50ish lenses. Or the Sigma 28/1.8. Or, if you'...

Because it's not that easy! Making a fast lens it's not just a matter of making "a bigger hole". The lens needs to "bend" the light to cover the whole frame, and the more extreme the bending (as in wide angle) the greater the aberrations...

Stitching is not mathematically correct. It is a 2D technique that works with image data. It simply warps the pictures to make them overlap without regard for perspective. Therefore it is confounded by perspective shifts when the camera view is rotated. For instance, lines which appear parallel when facing in one direction might converge in when the view ...

You're getting what is called Perspective distortion which is most noticable in wide angle lenses. Check out this link for more info: http://en.wikipedia.org/wiki/Perspective_distortion_(photography) Basically close up objects in the center of the frame will look enlarged while objects on the sides will be stretched away from the center of the photo.

Two things common to Wide angle lenses can do this, barrel distortion and perspective distortion. For barrel distortion, when pulling in a very wide amount of information from off axis, light gets distorted based on how extreme of an angle it is coming in at because the lens can't completely correct for how far off the lens axis the light is. On the ...

Any EF lens can be used on one of Canon's full-frame cameras. Generally, when Canon makes a newer version of a lens, it's because there can either be improvements to the optical design, or they can make a cheaper version of the lens. With Ls, it's usually the former. The Mk I version of the 14L came out in 1991. The Mk II version in 2007, so you ...

When looking for a wide angle lens you should consider a few very important things: Focal length Image Quality Maximum Aperture Focus modes (AF/MF) Filter compatibility Feature set (FTM, IS, USM, etc.) Mount Weight, size, cost, etc. Intended usage Distortion & Projection Flare resistance Most of the above is not uniquely important to wide angle lenses, ...

Probably not. The Rokinon/Bower/Samyang/whatever else it is being marketed as this week 14mm f/2.8 is a manual focus lens. That makes it difficult to use for photographing action. And while it is true that before the late 1980s pretty much all lenses were manually focused, it took many folks a lot of practice and years of experience to get highly proficient ...

First, some terminology. On your 700D (or any of the 1.6x crop APS-C bodies), a 15mm and up is still just "wide angle". It's below 15mm that lenses become ultrawide. So if you want ultrawide, you need lenses that are around the 10-15mm focal length range. Wide angle on a 1.6x crop camera, typically means something in the 15-24mm range. Normal is around 28-...

It's all about relative distances. Wide angle lenses don't distort, take a photo from the same distance as you'd use a 50mm lens and crop, and you'll see none of the trade mark wide angle look. When you get close to fill the frame, features that stick out such as noses are relatively much closer to the camera than the rest of the face so they appear much ...

I have the 14mm and use it with a T3i (still a crop body). I like it for what I get but I wouldn't consider it the best option. If time is not of the essence, I would recommend this: Canon EF-S 10-18mm f/4.5-5.6 IS STM Lens. It's only preorder at the moment, as this lens hasn't been released yet. It would, however, leave you with a lot more options than ...
