For cityscapes and general urban subjects, your 35mm prime is bound to be very good. When I do that sort of thing, I usually carry too much stuff with me: 12-24mm f2.8, 24-75mm f2.8, 36-300mm f/4, tripod, remote/timer, cleaning kit, batteries/cards/etc. Either all that or a compact cam and tiny tripod. You may want to consider keeping your prime attached, ...
More simply, what you are missing is that the lens on the iPhone is much MUCH wider than the lens on your DSLR. You have a 35mm lens on the DSLR, but you have a 4mm lens on the iPhone. The iPhone's lens is DRASTICALLY wider than the lens you are using on the DSLR, so comparing it to a 35mm lens isn't really comparing apples to oranges. Practically, you ...
@AJ said all that I would have said and more about kenrockwell.com; but I would like to expand more on your specific requirement (and on AJ's recommendation) as this is also the kind of photography that I do the most. For your situation of shooting mostly buildings where you can set the shot up, you are probably best served by following his advice ...
You're right that the angle of view of the iPhone camera is a little bit wider than a 35mm lens on a full-frame film camera. Up until this point, you're not really confused. But the part after that, about the small room and zoom and distance — definitely confused. :) "Zoom" means the ability to change the field of view — it isn't magnification. See What is ...
Which professionals? Different photographers obviously have different needs. As a rule, be suspect of any statement that treats the needs of such a large class of people the same. The Canon EF 24-70 f/4L is a very popular lens, but at $1000, it's not exactly targeted at consumers.
Rockwell is a moron (or more accurately he presents his opinion as fact even when it is actually a contested opinion). Yes, professionals use 24-70 lenses. They aren't for every situation, but there are plenty where they are great go to lenses. The Canon 24-70 f/2.8 II, for example, is one of the most popular zoom lenses ever. I do wedding photography ...
I recall looking through the viewfinder with one eye and around it with the other, figuring it would match at the "natural" size. It was about 55mm. But that's not necessarily right... Plus it depends on the nature of the print! Look at the final print. Say, a 4 by 6 photo, at reading distance. Hold it up, keeping the distance to the eye the same, and ...
When I take a picture with my nikon d5000 with a 70-300 mm lens,i have to set it at 100 mm for the object in the picture to appear to be the same size as my eye sees it.
Portraits can be taken at a variety of different focal lengths it all depends on the type of look and feel you would like. Traditionally a longer focal length 50mm and above is used but there really are no set rules as rules are meant to be broken every now and then! :)
It's actually even easier than that, since times below 0.3 seconds are commonly displayed as fractions of a second. So, "20" would be 1/20 second. Since you have a 35mm lens, that would correspond to 1/35 second or "35" (or the next higher available number). No need to go decimal here, just stay with fractions :)
Your calculations are wrong: 1/35 is 0.03 seconds and you can use 1/30 sec. (as standard setting and very close to 1/35) If you see 20 this mean 1/20 of the second. And with such speed there is probability you make blurry photos
Why is this? And why not? 50mm is 50mm and the adapter does not change anything (unless it is one of the very special adapters containing additional optics, like Metabones Speedbooster)
I'm just going to answer the 'is it allowed' question. Yes, and in certain circumstances, they have various restrictions. I know of a couple that restrict the physical length of a lens, regardless of focal length (no kidding). One baseball team that I visit periodically says I can't bring in a lens longer than 8". Check the team's / stadium's website or ...
I'm going to disagree with Jasmine here: this is the wrong lens for your camera. The 18-140 is a perfectly good beginner lens - but you haven't bought a beginner's camera, you've bought something designed for more experienced users. By using a lens designed for the lower end of Nikon's range (a "DX" lens like the 18-140), you are literally throwing away ...
The sports teams and venues set the rules for photography. Some events don't allow any photography at all. Best to check before you go, otherwise you will have to leave your camera in the car in the parking lot, setting you up for theft. Generally in the USA anyway, professional Baseball allows photography, Football and Basketball do not. As for how that ...
The focal length isn't measured by examining the field of view; it's an optical property of the lens. For real-world camera lenses, it's measured from the center of a theoretical equivalent single-element lens (see this earlier question). So... no, barrel distortion is not taken into account.
