What's the equivalent of a 50mm lens in digital photography? - 50mm lens equivalent 85mm on a dslr nikon d700
In the days when celluloid photography was all the rage, a 50mm lens was meant to human vision together. What is the equivalent for digital photography?

50mm Lens Equivalent 85mm On A Dslr Nikon D700 What's The Equivalent Of A 50mm Lens In Digital Photography?

In order to achieve a field of 50 mm with a digital SLR, you need to consider the focal length extension (which tells you how much more will the sensor on a 35-mm film frame) in the comparison.
Penax Nikon, Fuji, Samsung and Sony DSLR bodies all have a multiplier of 1.5, so you get 50/1.5 = 33.3mm-50mm lens. Or 35-mm lens.
With Canon, some models come with a full-frame sensor, so you can continue to use a 50mm lens, and some models have a 1.3, you need the lens of 35 mm, and some models (like the rebels and 30D use) has a 1.6 FLM, if you have a 30mm lens (Sigma a very fine version 1.4 wish).
Olympus has a multiplier of 2, so the use of a 24mm objective.
Perfect response, OMG, and he deserves "best answer" honors. Tuthutop guess question on a digital SLR lens, because there is no alternative to point and shoot camera has, but it opens up the possibility that some consideration of the lens 'normal' in other cameras.
I do not know where to put it to be made, is so trivially inclined to, I propose the following ...
The true "normal" is determined by the diameter of the objective of the field relative to the size of the film. A lens has a circular area, as recently discussed in another question. The "normal" focal length would be the size of the diagonal, where the size is a square. Otherwise, the "normal" apply a contact lens will haveLength of the diagonal would have been like if only the frame is square.
In the 6x6-square (60 cm x 60 cm, 2 ¼ inches x 2 ¼ "), the diagonal size of 84.85 mm, so the goal is as normal, 85 mm. Rollei Mamiya Hasselblad and accepts 80 mm guard" normal. "fairly closely.
In the 35 mm, the longest side of the site 36 mm. The diagonal of a square of 36x36 should be 51 mm, 50 mm and is quite narrow. I remember the leaders in 60 to 55 mm is considered normal.
With digital cameras there are many sensors of different sizes, so there are different "normal" lens.
GM has the perfect answer for most Nikon and Canon digital SLR, I will not belabor that point. You can do the math yourself if you are terminally NewsNotes.
The other two sizes of digital photo sensors are used as 1/1.8 "1/2.5". I have no idea how to explain these terms, but the actual dimensions are about 7.2 mm x 5.3 mm for the 1/1.8 "sensor, and approximately 5 x 4 mm for the 1/2.5" sensor.
Doing the math, I think the "normal" focal length of these cameras would be around 10 mm for the 1/1.8 "and about 7 mm for the 1/2.5". Well, maybe watch "5,8-24 mm on the front of the lens is not as confusing for someone out there interested. No wonder that none of these cameras can get bokeh!
OMG and Dr. Sam, who deserves all the glory. Fortunately, there are not many people like you two in the Spanish-language versions of this forum.
To find Tuthutop, congratulations, a destination for your digital camera. The type of photography can be achieved with a cousin who has a totally different environment that you can get one of these that provides a slow zoom cameras today.
Take care!
