What's the difference between the 12mm and 25mm? Does the 25 offer the ability to shoot closer, and if so, how much closer?

Yes you can shoot closer but how close is determined by the focal length (mm) of your lens.

In simple terms, the bigger the number, the greater the zoom. The 17-50 will allow you to get close and to shoot wide angle. The 28-75 will allow you to shoot a little farther away. You probably want the 28-75 unless you need to get super close to something. I have a 17-50 and a 70-200. I use the 17-50 to shoot basketball games and get right under the basket. I use the 70-200 for football games because the action is farther away from the sideline. Unless you need to get really close to something, or need a wide angle (like a dance group at a rally), you probably want the 28-75.

I really enjoyed my Sigma 30mm, but the 24L is something different. $1100 is worth different things to different people. I found it to be a better focal length on a crop sensor (7D) for general indoor low light shooting.

Some people need more than just 14mm. Shooting at 24mm, or anything in between, can create a drastically different image. I use this lens to shoot interiors for real estate (amongst other things), the zoom aspect is invaluable in tight spaces and also allows me to achieve the right balance between rectilinear distortion - which is often very noticeable at 14mm - and the desired field of view.

David, have to explain that I do not own a 24-105L only a 24-70L, but I have seen the results that they produce and both are great, obviously the 24-105 gives you a little more reach. 24-70L with the 5D MKIII has worked really fine it is a great lens in a great body. If you are choosing one I would analyze my other lenses or what you will buy in the near future. Other than that both are excellent lenses. Hope this helps.

This is the difference in the fixed lenses on the unit. 2.8mm gives you the widest view and is generally the most common, 12mm gives a zoomed in image. So if you are putting the cameras in a tight room go with the 2.8 if you want to see down a long hallway or view far away go with a higher one.

I haven't used either of the lenses mentioned here but I thought I'd point out something that hasn't been mentioned yet. You say the 12-24 has an aperture range of f4-f5.6, and the 11-16 has a range of f2.8-f22. Actually- in the 12-24, the numbers you mention are the maximum aperture settings. At 12mm it opens up to f4 max, and at 24mm it opens up to f5.6 max. At any zoom range it would stop down to probably f22. So the 12-24 is not limited to only f4-f5.6 as this post suggests. The 11-17 lens has a constant maximum aperture of f2.8 through its whole zoom range, and also stops down to f22. So both of these two lenses have a normal range of apertures, but the 11-17 opens up to a bigger f2.8. Just thought I'd point that out if anyone was misled...

The 24 is a good all around but I think the 20mm 1.7 would be superior for low light interior shots.

That's a bit like asking what length of string should I use? First question; what is the application? Second question; crop or full frame (FF)? Third question, what focal lengths do you already cover? On FF the 24mm is generally a better landscape lens than a 35mm and 35mm is generally better for journalistic type photography, or just walking around. On a crop, 24mm is about the same (a little longer) as the view one would get from 35mm on a full frame. I love the 35mm on a crop as well, which is closer to the classic "standard" lens (50mm), which will be generally better for street. When I say generally, I mean that it is often more appropriate to use one focal length in these situations that others, but I have seen portraits with wide lenses and telephotos used for landscapes to great effect. Sorry, I dont believe a better answer can exist without additional information.

I bought the 24-105 lens recently because I thought the IS would make up for my lack of a higher aperture in low-light situations. It does to an extent, but I have decided that I want the f/2.8 for other reasons. So I'm trying to sell my 24-105 so I can buy the 24-70. I do wish the 24-70 had IS, but it's really not necessary because it's just a faster lens. It really depends on your use. If you are using it for weddings, you may want to consider the 24-70 because of the faster focusing and better handling in low-light situations. If you are using it for a general walk-around lens, the 24-105 will do just fine. I love mine and I almost want to keep it and buy the 24-70, but I can't afford both right now and I need the 24-70 for my business. You can see some sample photos from the 24-105 at my website: www.sarakelley.net. Email me there if you want more input or have any questions.

This lens has a wider view so you see more. It's a little heaver and bulkier than the 85mm, but you can stand much closer to an object that you want to have in focus (12 inches) as opposed to the 85mm (about 3-4 feet).

The Tokina 12-24mm is a constant F/4 throughout the zoom range (from 12-24mm). It does not drop the 5.6 on the long end.

I chose the Olympus 25 mm over the LUMIX 20 mm because of focal length, just a little more flexibility, and price. Difference in speed was inconsequential.

Id say pick the 17-35 if you intend to stay on DX size for another 5yrs... the 50mm covers the middle of the 24-70 so moving your feet will cover that distance, but the 17-35 will allow for group shots and landscapes/buildings... the 24 will limit that somewhat.... my2cents!

Generally, it is a personal style/preference depending on the desired effect. If you're looking to up your game with the subject matter you've mentioned, I wouldn't buy a 24. If you're shooting with an aps sized sensor you're gonna have a multiplier effect on your lens making you 50 even better a lens. I would, in your situation, investigate a fast (2.8) zoom lens in the "standard" range (28-80). I love canon's 17-55 2.8is. This awesome if you have an aps size sensor. Good luck!

since the aperture (f) is the same for both, the difference is the zoom. the 75 starts magnified more and can zoom in more than a 50-250. so 75-300 starts closer to the object and ends farther

Sharp lens, at 120mm its longer than the 1.8 45mm, which works out to 90mm. It is a bit slower, but just as sharp. Yes and no, it gets you close from the edges of a room, head shots are fine, its a cheaper alternative to the oly 75mm.The 25mm 1.8 might be more useful, I have the sigma 60. Do it all would be the pro zoom, but its pricy. The sigma would be great on the omd, at the price it'd hard to beat. If you do not have many primes, its a good start.
