9-18mm Limitation

[nex100]

the 12mm prime has barrel distortion. If you are olympus body then it is ok as the body does auto correction for this lens. at f2 you cannot find a faster lens.

Perhaps it is just me and I have not fully understand how to use this UWA lens. As you see from this shot , the reflection is okay, but when I was at the Garden by the bay over the weekend, I couldnt take any clean shots with nicely reflected images in the water. Or it could just be the angle and distance I am at but I shall try the same scene again this weekend.

Care to show a picture taken at Garden by the bay? I don't quite get what you mean without a comparison

I didn't posted at my flickr and don't have it with me now. Maybe I post 1 tonight for you guys to see then you will understand what I mean and give me some advise on it.

Just want to share 1 fantastic use of CPL filter even in UWA.



The red path was originally pinky white but I managed to use the CPL to reflect some sunlight off to make it look red again.

As promised, here is the shot I took, i must say, I was totally not happy with the results, I am going back there again this Saturday because I could have got the configuration and some camera setup wrong wrong.

As you can see from the reflection, its weird...

 

[spidey89]

Interesting... Could be shutter speed as well as distance from the water, I'm just spit balling here, could be any other reason, though it could be shutter speed, more time for the water to move and blur from what I can see

I should have increase the aperture, or rather make it narrower, that will increase the shutter speed. Don't know why I didn't do that in the first place. I shall try that this Saturday and feedback here.

Another thing, I realized my noise filter setting might have affected the quality a bit. I will try to use Low instead of Standard, then use LR or DeNoise to remove the noise. That will keep the detail I hope...

I agree with Spidey, it is most likely the movement of the water.

You can see the same effect here (15s exposure) :

 

[spidey89]

noise filter is for high ISO, use the noise reduction to remove the noise during long exposure

Then I have been thinking too much I guess. Maybe that area, the water wave move stronger because the more I think about it, the more weird I felt, by right distortion shouldn't even be present in the center but it seems to be present in the photo, so, Spidey and elgkh most likely are correct, it is the movement of the water. I shall try the theory this Saturday with high shutter speed and low shutter speed at the same scene. Shall feedback you guys.

You know, this thing have been bugging me. I was playing safe with Low Noise Filter. My noise reduction is set to Auto but I just got the feeling that my noise filter set to Low, even Low is removing some details away from the photo. Therefore I did a little bit of test yesterday night. I did 2 shots with f4.0 f8.0 f11 each with Noise Filter set as low and none. Interestingly, setting it to low kinda made it a bit less sharp with the one with none having a bit more noise, just a bit which made it almost unnoticeable and if I didn't zoom in to check but it is sharper.

That is normal. Shoot with noise filter off to get more detail. You want even more detail, shoot in RAW...obviously.

I will do that this Saturday. Gonna also do RAW shots for night scene.

Now that I think of it, might be the how much the water moves as well, the first shot should be a river right? and the 2nd is like the sea, probably the sea has more movement than the river

Do as Oly5050 suggested, as the saying goes "if it ain't broke, don't fix" so in this case, if you're shooting low ISO, don't use noise reduction, that day I shot with my IS on when using a tripod, was thinking for a sec why my images came out blur despite being on a tripod, check my settings, chey! its IS that's on hahahha

My 2 samples shot with the 9-18mm. The reflections look ok to me. The water is more turbulent nearer to the bank hence the reflections will be more distorted.

I want to see if I could use the "distorted" reflection in any creative way. But you are right, first thing first, I am not so sure about the noise reduction because I will be doing long exposure but Noise filter will have to be off. IS too since I will be using tripod.

Ya, you are right, can see a bit of distortion nearer to the bank, but not as much as the one I took, do you think it could be the angle you shot it and the angle I shot mine? I think it might... hmm...

 

[vainqueur]

This shot was taken at the Punggol waterway, this one is less distorted most likely because the water got less turbulent
