700D Blurry shots

Debashis_A_ghosh

I have recently purchased a 700D and use it with my EF-S 18-55, 55-250, EF-50 and 100 f/2.8. With the 55-250 I notice that even with a fast/low exposure time I seem to be getting blurry shots. I have seen this issue with both the IS on and off. My worry is could it be the lens or could it be the body ? I know that I need to check this lends on another body and a long range lens on this body. While I do that I'd like to know if some of you could help me identify the issue.

Sadly, none of the links in your post work, so we can't see what you wish us to see.

From the attached image, I see some slight Red Blue - Chromatic Aberration (CA). The Canon EF-S 55-250mm f/4-5.6 IS is one of Canon's least expensive lenses, in the "consumer" class of lenses, and lacks some of the quality of Canon's most expensive lenses. The image crop in your attachment:



... appears to show the CA, which is most apparent with an extremely high contrast subject matter like that of the signage.

There are much better lenses available, and I can recommend:

Canon EF 300mm f/2.8L IS II USM
Canon EF 300mm f/4L IS USM

, both of which can soundly beat the EF-S 55-250mm f/4-5.6 IS in almost any regard at f5.6 aperture.

Yes, both your EF-50mm f/1.8 and (especially) your EF 100mm f/2.8 Macro USM will also beat the EF-S 55-250mm f/4-5.6 IS at their respective focal lengths and middle apertures, but almost any decent prime lens can beat an inexpensive zoom lens.

Congratulations on your Canon EOS 700D/dRebel T5i. Very nice upgrade from your EOS 450D/dRebel XSi.

PS: I merged your two threads and deleted the duplicate post.

Thanks for the response Ziggy. I was unable to locate the earlier post. My flickr page is here: https://www.flickr.com/photos/debashisghosh/ you can see the first three shots there. If that looks like CA to you then I can live with that. What prompted this thread was blurry shots of the moon on a tripod with IS off in both MF and AF. It
was just out of focus. I have shot the moon before using the 450D https://www.flickr.com/photos/debashisghosh/14169842746/in/photolist-nA99zy-bpgjsP-5ShEx9-khEsMN

The easiest fix is also the use of a Tripod !

That is my worry. I had used a tripod and it still gave me a blurry shot.

Taken on the 450 D and the second one on the 700D

For lunar/Earth's-moon photography:

1) Use a sturdy tripod. I note that you used a tripod; good on you for that. The sturdier the tripod, the better the results.

2) Set up in a stable environment. Next to a highway with heavy trucks, or near a heavy construction area would be bad environmental examples. You need stable and vibration free ground for good results.

Avoid windy conditions for the same reason.

3) Make sure lens and camera body stabilization is turned off. Some IS systems will not properly detect a tripod use and can create blur instead. It's always better to just make sure IS/VR/OS is turned off when using a tripod. (The exception being pan-only IS settings and a panning exposure.)

4) Make sure that focus is manual and set accurately. Auto-focus is not reliable for lunar work, in my experience. Use Live View when possible to set focus manually, take a shot and review with zoom to confirm focus.

Thanks Ziggy and Gatto. I will try and get this shot again just to see if I can get better results.

I didn't see it mentioned, but it can be the lens (or body) also. You can test the autofocus with a couple of different methods. I had a lens that I bought that didn't give sharp images with my only camera at the time. My only option was to send it back, but ended up getting a new body before I did that. Lens focused fine with the new body. Which was fine, but the new body had the ability to let me tweak the AF. Didn't need to use it.

Anyway, here is what I used to test my AF on all my lenses. http://regex.info/blog/photo-tech/focus-chart

Some good advice above. I'd second the point of checking to see if you can get a sharp shot with manual focus rather than auto focus. Also don't go too high on the f/ numbers if you are doing as you'll tend to lose some sharpness due to diffraction doing that! What are the exif settings on your moon shot by the way?

that original full size pic doesn't look too soft or blurry - stop looking at 100% crops !!
sure the 55-250IS is a $100 lens but it's sharp, lightweight and (literally) pocket size. Even though I have better lens I still keep the "consumer" 55-250IS
