You need an ultra-wide angle (12-15 mm effective focal).

Is there a difference between effective and inefficient focus?

about this sentence

Ivanlabuda @ 05/11/18, 15:35

Canon 100d or 1300d body (i.e. without lens)
Canon EF-S 10-18mm f / 4.5-5.6 IS STM lens

Will the difference between 8 mm and 10 mm in the photo be big? Review greatly reduced?

: D
There is a real and effective focal length.
What is written on the lens is real.
What is obtained in combination with a specific matrix (frame size) is effective.
Recalculation is just the angle of view.

On a matrix like the above-mentioned carcasses (crop 1.6), an 8 mm lens will give a viewing angle of about 120 degrees, 10 mm - 110.
For comparison, the first of your examples is an angle of about 55 degrees (27 mm EGF).

Here are some details..

ivanlabudathank you ...
Having read your post, I realized that I need not a camera, but a gun :(.

Ivanlabuda @ 05/12/18, 06:04

Here are some details.

Semyon-Semyonych .... my brain exploded before reaching the formula
Field of view = 114.6 в‹… arctg (21,622 / (S в‹… F), В°

Ivanlabuda @ 05/12/18, 06:04

For comparison, the first of your examples is an angle of about 55 degrees (27 mm EGF).

I dare to ask - and the second photo?

Returned to the recommended kits:
Canon 100d or 1300d body (i.e. without lens)
Canon EF-S 10-18mm f / 4.5-5.6 IS STM lens

Nikon d3300 or d3400 body camera
Nikon lens 10-20mm f / 4.5-5.6G VR AF-P DX Nikkor
And which of the numbers on them shows what it is (block 1.6)?

my brain exploded before reaching the formula

: D There is further a sign "focal - cropping - angle".

George 18.05.05.18, 16:39

I wrote about the second. Focal - 8 mm on the crope 1.6, it is about 120 degrees. I will clarify: this is the angle diagonally of the frame, not horizontally.

George 18.05.05.18, 16:39

And which of the numbers on them shows what it is (block 1.6)?

None Crop factor is calculated from the geometric size of the matrix. Better just believe: D
For these canons - 1.6, for Nikons - 1.5 (that is, on one focal nikon it will give an angle slightly wider than canon).

I believe :)

Here I bought a used Nikon camera. What do you think?
bottom view


I chose that there was no bluetooth or wi-fay.
will the lens that you advise approach it
Nikon 10-20mm f / 4.5-5.6G VR AF-P DX Nikkor?

!!!!!!!!!!!!!
This lens is compatible with 3300/3400.
With 3100 will not work !!!!!!

UPD: fitthisbut it is more expensive.

ivanlabuda
thank you very much.
Read all the reviews.

I tried to take a few pictures on the bought Nikon. To him in the appendage attached free lens
AF-NIKKOR 18-55mm 1: 3.5-5.6G
Since I used to use only a soap box, I set the automatic mode.
Regular photos came out, well, I did not expect anything special.
Only for some reason, when viewed on a computer, literally in a second they become darker.
What kind of phenomenon is this?

[ivanlabuda]

George 18
Attach a snapshot, see.
I use for viewing (and small processing, if necessary)this program. Very comfortably.

About the lens width:
The d3100 is an old device, does not support new autofocus Nikon lenses with AF-P marking.
If you buy in a store, come there with a camera and check the lens on it.

here I post it.
but first I had to change the format for Picasso.
There was NEF and it was not in this format.
the system analyst prompted what needs to be changed to JPG through Picasso
Well, the result

Here it is darker than in the original, but at least it does not blink, it is already good.

Thanks for the program, I have never used it, I'll try it at my leisure.

NEF is a Nikon format containing raw data from a matrix.
This is something like a “digital negative” that requires mandatory “development” in programs like lightroom, capture one, camera raw and the like.
You can draw out shadows / lights, correct color, remove distortions, etc.
The common format name for all cameras is RAW.

If you need to quickly - set the camera to shoot in jpeg format (documentation is here).
If you want to get "beautiful" - learn to process raw.

Well, sort of, and in Picasso, we managed to change the format. You can also lighten up.
There is no time to master new programs. But thanks anyway - it is possible and useful :)

But with the lens still does not work. Already almost all local shops sent a request, and phoned ...
There is another option - I will ask 2 friends who seem to be engaged in photography and buy-sell photo equipment.
Ordering on websites is problematic - what if it doesn't work?

And what do you think - can you buy a battery for d3100 somewhere else?
Or you can work with the cord from the network? It is inconvenient, of course, but if the akomomulyator will quickly sit down, then I do not see another option. It seems to have seen such an option in the instructions, but I'm not sure.

Akkum called EN-EL14 (or EN-EL14A), sold in many places.
“Native” new should be enough for 500-600 shots.

As for the compatibility of lenses, you need to look at the manufacturer's website - they usually write for each lens which carcasses it is compatible with.
AF-P Nikkor is definitely not compatible.

[George18]

ivanlabuda

Thank you for enlightening Akkum.

Objective: AF-S Nikkor. Last time I missed it.

[ivanlabuda]

George 18
I know i understandAF-S fit.

[George18]

Ivanlabuda @ 05/16/18, 14:11

I understand, AF-S are suitable.

ivanlabuda
Well, yes, that view from the window was made by this lens.

Yesterday I studied the instructions for the d3100 herehttp: //www.nikonsuppor…3100/D3100RM_En_04.pdf
it says 200/216 p. about the lens
AF-S DX NIKKOR 18-55mm f / 3.5-5.6G VR
that he has a maximum angle of 76 degrees on his passport.

I have an AF-S NIKKOR 18-55mm 1: 3.5-5.6G lens
Maybe you know - what is his maximum angle?
In general, I want to thank you for your help, otherwise I am torn between work, my disabled wife and our old mothers ...

The viewing angle of the lens depends on the focal length, taking into account the crop factor (size) of the matrix.
I already gave the link to the tablet.
For any lens 18-55 cropping 1.5 it will be from 76 to 29 degrees diagonal frame.

[Ice-kiling]

People, well, you and pile up ...

The theme is certainly old, but ... considering the budget is the best option -buy action camera(ivanvias already wrote about this), they have a wide angle, depth of field is high, only the lighting should be good.

Everything, then you can throw off a few models, but in fact it depends on your finances.

For shooting apartmentsThis is the most budget optioneverything else at times more expensive.

George 18
If the question is still relevant, then this is a great option.

force majeure intervened and had to postpone everything.

Now this question has become acute again.

Ice-kiling
And the action camera is a GoPro or something?

we tried to rent an apartment, gave our acquaintances a try - maybe the angle was too big, but nothing good happened.
Solid fish eye.
They wanted to ask them again, but they lost this camera somewhere: (

Now the thought came - maybe you can hire it and then try it out calmly :)

-----------------------------------------------------

And yesterday I went to the store and took a picture with my Nikon and the shop lens
Sigma 10-20mm f / 3.5 EX HSM DC.

That's what happened


for comparison, the same angle - soap box


the same angle Nikon with a conventional lens


It can be seen that the Sigma 10-20mm f / 3.5 EX HSM DC has a much larger viewing angle.

Now I’ll break my head - take this lens or try GoPro .....

You can and GoPro.

Distortion will be because This is still a wide-angle action camera, you can fix it through Photoshop / Lightroom / ptgui and other similar applications. (with falling detail around the edges, although this is not so important for shooting rooms.)
Some modern cameras independently rule distortion when working with compatible lenses.

If the issue of price is not important, then you definitely need to take a system camera with a wide-angle lens (+ a tripod, of course), but if the issue with the price is important, then the action camera will help you something more budget even hard to come up with.

P.S. A good lens can come out more expensive than an action camera, and there is also a camera, which can result in a price of several action cameras.

Take this Sigma !!! I have a canon 10-22 and an action SJ5000xElite - yes, the action angle is greater, much more, BUT !!! This barrel is really almost impossible to remove and long! And the final picture with the action is good only to “fix” what is there despite the distorted proportions. The action itself makes a software elimination of distortion - this is when shooting: instantly and not bad, but at the edges something absurd happens with proportions.
Maybe someone is satisfied, but compared to 10-22 - sucks!
