Lenses??

kpilon — Wed, 30 Sep 2015 14:27:15 GMT

I want to get a lens but it says (Lens for Canon Rebel T5i T5 T4i T3i T3 T2i T1i XT XTi XS XSi SL1, 5D Mark III, 5D Mark II, 6D, 70D, SL1, 60D, 7D, EOS 700D 650D 600D 550D 500D 450D 400D 350D 300D 1100D 100D DSLR Cameras).

My question is can you use a lens designed for canon t3i on a t3
I have a Canon t3.
Thanks

Yes you can.

Both T3 and T3i are crop sensor bodies. Crop bodies can mount both crop lenses (EF-s) and full frame lenses (EF).

The lens ad you posted says it fits both crop bodies and full frame bodies, by the way.

What at lens is it?

I want something for landscape photos& taking photos of the moon, etc. Any ideas?

What is your budget?

What other lenses do you already have?

Would you consider two more specialized lenses rather than one all-purpose lens? Any all-purpose lens has to make optical compromises in order to cover a big range of focal lengths. As lunar photography and landscape photos are (pardon the pun) worlds apart, you would be stretching a single lens pretty thin to do both. Typically a landscape lens is rather wide, and a lens for shooting the moon would be a very long lens.

I agree with Scotty. Landscape lenses tend to be wide, under 35mm. Meanwhile you definitely want a long lens, 500mm and up, for moon shots. Be aware that not every wide lens produces a flat image. Most lens will introduce some fisheye effect as you go to shorter and shorter lenses. Some wide lenses are designed to specifically not do that, like the EF 14 mm f/2.8L.

For moon shots, you would also want a heavy duty tripod that can support at least 3-4 times the weight of your lens/camera setup, and don't forget to add in the extra weight for your tripod's head. Most tripods are rated for a maximum weight with the center column lowered, and the weight centered on the tripod. The weight of your camera/lens will go pretty far off-center when you tilt your setup towards the moon. Be aware that some long lenses with tripod mounts are better balanced than others.

Tamron 18-200mm
Tamron 70-300mm
Tamron 24-70mm

I was looking at this lens

(http://www.amazon.com/Tamron-AFA011C700-150-600mm-5-6-3-Cameras/dp/B00PIVCGDA/ref=sr_1_26?ie=UTF8&qid=1443585216&sr=8-26&keywords=canon+lens+400mm+%26+600mm.&refinements=p_72%3A2661618011)

I am willing to look at anything. So ideas of what to get would be greatly appreciated.

You could really do the landscapes pretty well with your 18-200. Unless you need a wider lens than 18mm for the landscapes I think you could tackle the long lens first. if you need wider look at Canon or Sigma 10-20 or 10-22 lenses. They are for crop cameras so they are pretty affordable.

For distance, the Tamron seems to fit the rest of your Tamron kit. Sigma makes a Contemporary zoom that goes to 600 that is considered pretty good too. I agree with the above that a good tripod would be great.

For both

Thanks Scott for the information. I appreciate it.

Here is a Moon shot done with the lens you are considering. Is this what you want?

600mm f11 1/1000 ISO 100 (The "Looney 11 Rule")

Makes a nice 'landscape' lens , for the Moon!

Yes that is what I am looking for. I used to take a lot of photos years ago with Canon AE1 but I have since updated to the Canon EOS Rebel T3. So I am looking for any tips.

I think Ernie was pointing out that even 600mm lens on an aps-h body giving a 1.3x zoom boost does not give a very close up view of the moon.

Your camera boosts a bit farther, giving a 1.6x apparent boost but that would still not be a serious closeup. For closer than that you'd need to get a lens that can mount a 2x telefolks converter, which means an f/4 or brighter max aperture or else you probably lose autofocus. A lens like that costs a lot of money though, not to mention the teleconverter. Check before you attempt to be positive any lens you pick will let you even mount a teleconverter without glass hitting glass.

There re are also ways to shoot using a telescope as a lens but I know nothing about that.

The same Moon image as it comes from the 1D Mk IV looks like this.

It is impossible to get good shots of anything in the sky without post editing. Period, end of story. The first example is an enlargement of this photo. It has gone through lens correction in Lightroom 6 and has screen sharpening applied upon web reduction.

Instead of a tele converter you need to get some type of post editing software. For most folks Photoshop Elements is the best there is. For the more advanced or more serious Lightroom and Photoshop are as good as it gets.

A tele converter helps with magnification but it hurts everything else. Post editing improves everything!

I use use a telescope for a shot of just the moon.

A shot taken near 1st quarter provides lighting from the side and offers a more three dimensional look because the craters cast shadows.

For a "full" moon, I find it better to check your calendar and shoot 1 day BEFORE the full moon. The moon will rise just before sunset and you can get the moon in a dusky blue sky instead of a black sky. This gives you the option to includes some foreground interest so it isn't just the moon in your shot. The moon will still appear "full".
