Space Lens for Canon 700D

[Betabot]

So lately I have bought a Canon 700D, and would like to start getting into space photography. I'm pretty good with a camera's manual controls, although need more practice with manual focusing.

 

Ive been looking around and come to the conclusion that the Samyang 24mm f/1.4 could be the one to get. I know that it's mainly for Full Frame cameras but is still good for cropped sensors.

 

I was just wondering what people thought about this, or if they have a similar setup. Also would there be a major difference in quality in using that lens on a crop sensor? I can't find any shots of the one lens on both types of sensors.

 

Thanks

id probably get the 14mm or something for your camera, since the 24mm with crop ends up like 38mm where the 14mm ends up at like 22mm

 

Are you ever intending to move to full frame? 

[Betabot]

Well my other main choice was a 16mm at f/2.0 but it only states APS-C. Therefore I was thinking that if I do ever upgrade that's one lens that I lose, unless I'm thinking about that wrong as well.

 

Why wouldn't that lens work with a full frame? I guess I'm trying to think both in long term of if upgrade, and my best choice now.

A lens for APS-C wont work on a Full Frame because the rear element is smaller, made for a smaller sensor. Being that the image cast from the element wouldn't be big enough to cover a full frame sensor. 

 

 

As for a "space lens" I recommend primes, Since your camera has an APS-C sensor when looking at full frame lenses calculate the sensor crop. 

APS-C is 1.6x Crop Factor

 

For instance 24mm x 1.6 = 38.4mm

If you plan on going full frame then this lens is compatible with both crop and full frame.

If you plan on staying on APS-C then this lens is faster which will let in more light.

Both are highly recommended and excellent for astrophotography.

So it pretty much comes down to the question if I would ever move to Full Frame in the nearish future. hmm

 

Thanks everyone, I'll try think through it and either get the 16 for APS or 24 for Full Frame (APS temp)

or a FF 14mm Samyang

 

honestly there are a billion options, you need to decide if you will move to full frame, and if you are sticking with Canon etc

I haven't seen much about the 14mm, is that the f/2.8 one?

 

Yep I realise there are heaps out there, I will definitely be sticking with Canon, as I have quite a few around that it is possible to share lenses with. Main reason, is no one has a nice lens that would to a high degree in Astrophotography. Which is why I'm thinking of going with the 24mm option.

Yeah, nice and wide! especially on full frame where it really shines

 

Yes but if you move to full frame ,you will have no lenses so you will most likely be starting again from scratch  

but yeah, any of the Samyangs are nice lenses - bear in mind they are MF only (there are some FE AF coming out soon dunno about canon)
