Wide angle ----- Fisheye

[Upatdawn]

I have a Nikon d5300 (crop sensor?) which - i understand - means the stated focal length of a lens is increased, what would be a wide angle lens, i have a 18-140mm but assume its not 18mm with the "virtual" increase from me having a 3/4 sensor? and when does a wide angle go "fisheye", lower than....what mm?

The focal length is the same no matter what sensor. 18mm is stil 18mm.

Your angle of view changes (as well as a few other things) , but basically you can multiply any focal length by 1.5 to get the effective working focal length on your camera.

So 18mm on your camera will be like 27mm on a ff camera ( d610, d800, d3 etc).

For wide angle you are looking at 10-14mm or so.

Most lenses are 'rectaliniar', but fisheye is a special type of lens that does not correct for straight lines.

You can have a 12mm fisheye and a 12mm rectaliniar lens, both will give a different look. Fisheye lenses are IMO qutie specialised and not really for normal shooting though some people can really make them work.

Hah!

Fisheye lets you take an unusual photo in a common destination, that's what I love about mine. But women hate it

'Angle of view' is probably a better parameter then mm. Do you want an ultra-wide angle (UWA) or a circle effect? (the novelty of which will quickly wear off)

I've used the 10.5mm Nikon fisheye. Fun but very limited use.

I could never justify buying one. If I needed it for a specialised shoot, I'd just hire it.

I used to use a 16mm on a FF, that was wide enough IMHO. Mainly because I doubt I would have been able to make anything wider work.

As has been said though some people really make UWAs work.

Thanks, I was reading the op and was about to ask a question which, I think, you've just answered.
Basically my son who has a Sony A58 wanted a Samyyang (sp?) fish eye lens but I was explaining to him he may be better off getting something like a 10- 22 mm lens, I just thought the fisheye might only get used at first and then when the novelty wore off he'd end up with a lens with limited uses.

Well i LOVE my Samyang 8mm fisheye on my 7d. Limited day to day use but for my sports photos and times when you need to go wide, tower of London poppies from yesterday for example
then it is just just fantastic!!

Had someone on my photo walk this year just rocking a fisheye and they made it work really well.

The fisheye can be amazingly versatile, but you need to work hard!! Get it low to the ground for some really wide looking shots.

I guess my real question was when do I get fisheye images on a crop sensor camera, at what actuall lens focal length, 18mm = not (i know) what about (say) 12mm? lower?

You don't, a fisheye Lens is a different kind of lens to a normal one.

[Simpo Two]

Yep, a normal wide angle is designed to make a rectangle. Hence it's not just a question of focal length; it doesn't suddenly become a circle below Xmm.

Fisheye is the only lens I would never get rid of, since you cannot replace it with anything else.
