Bro I had try the Sigma 10-20 but also got hot spot.... if not can pass to u.. Or Bro lowlights u wan to try?

My friend used it for IR and it has no hot-spot when both of us were in Siam Reap early this year. If i am not wrong, Sigma 10-20 is best for IR at 5.6 and below.

Wow so many thing to consider...
You will it work well with a d70 elp ? I have no wide angle lens yet can consider.. Hotspots?

Tokina 11-16mm??!!!
Haiyah.. fancy you ask me about this lens.
It's a GREAT lens for normal colour landscape photography.
But for my Hoya R72 on the Canon 20D, it was utterly hopeless!!!
HOTSPOT ALL THE WAY!

You better test out the Nikon Mount on your ELP first.
Why? Let me explain to you why:

• some people have found that certain IR filters give hotspot while another IR filter on the same machine doesn't - using the same lens. Thus if I were to change my Hoya R72 to say, a cheap China brand R72-like filter, maybe (only maybe) the hotspot will disappear, even on the Tokina 11-16mm.
• For some reasons, some have found that for the same filter, same lens but on different makes of the camera (e.g. Nikon and Canon) there will be different results in terms of hotspots. I know SurrealDreamWalker uses the Tokina 11-16mm on his Nikon IR. And he has no hotspot. So you got to confirm with him.
• And finally, you are using the ELP. Apparently better in terms of hotspot problem. This, the best person to confirm with again, is our good Chief Engineer.

Thus as we can all see, varous lenses have varying reviews - both on-line and personal reviews.
the best is like what LowLights said - go test it out himself - today!

I also have mixed results with the Sigma 10-24 on a converted D60, D50 and D80. At higher aperture you get little to no hot-spots. But with aperture of 8 and below IR becomes very obvious but not to the point of getting your photos useless. You can always "paint-out" this hotspot if it becomes too obvious. Some of my friends say that Nikon 12-24 is IR friendly... I'm about to give it a shot... waiting for my Nikkor glass

 

[LowLights]

All on a D50 .. ELP


Tokina 11-16

Sigma 10-20

Tamron 10-24

Nikon 10-24

So what you guys think ?

I was borrow this for test from shops and hence was in haste to quick complete it

 

[LowLights]

For those wondering ..

Tokina on D3 @11mm

Tokina on D3 @15mm.. close to 16mm

Megapixel remains 12mp despite a crop factor lens

Cheers

Thank you Lowlights for sharing your report.

You must be a very special customer.

D50 is very nice for IR

 

[limwhow]

No visible hotspots, you lucky fellow.
What aperture were you using?

Yes D50 is .. But much like to have D90 .. Don't think a few sweet words you can get a way :bsmilie:

 

[LowLights]

5.6

Did try 8 .. Looks alright .. No spot too .. Tested 5.6 cause always shot at 5.6

You haven't bought it yet, right?
Today your shots.... not bright enough... maybe.
Was it sunny enough, you think, LowLights?
Why I asked this was because of the very very slight hint of something in the central portion of this photo.
Just thinking... just thinking only... if the lighting conditions were a little different, would there be more pronounced central brightness?
Just thinking only...

Hahaha ... You the man .. I did not buy cause the photos all look suspicious .. It was bright .. But not IR type of bright .. I have the same suspicion as you .. What happens if it is really bright .. I think we will see the spot...
Just for the record the time was 1.30 there about..

Bro .. You single out the Sigma photo is this the one that looks like it going to give birth to a spot .. Or you feel all have the potential to have hot spot..

LowLights, Ok... since you pressed me to give you my opinion, I will:

• Tokina - the central irregular zone of brightness (uneven) is, in my opinion, a hotspot waiting to sprout when the light is bright. My experience with my Tokina 11-16mm is like this - sometimes when the sun is behind me or on my shoulder and the angle is just right - no problem. But when the sun is at any angle in front of my shoulder, that is when the hot spot will emerge. But then again, a great number of my tokina 11-16mm shots have hotspots. Don't know why. Maybe it's my Hoya R72. Here: this one the Tokina -

• The Sigma - as i have mentioned in my previous post, the central uneven area of brightness looks suspicious. If you give it great enough a boost, the Red is going to come out screaming at you, either through PP or through natural bright sunlight. I know what you mean when you say it's not that kind of bright IR light. Yah, give it a great bright IR sunlight and maybe the hot spot will come.
• The Nikon looks best.
• Tamron still looks as though something is there.

Sh*t. I sound so cynical.

 

[LowLights]

Yup .. totally agree .. when I first look at the picture on that miserable LCD of the D50 .. I was convinced that there was hot spot for all tested lenses

then when I reach the Nikon .. I decided to shot a different angle and as you may guess .. no bloody hot spot .. so I took the Tokina to test again and .. damn no more hot spot ... but I call it the day as I suspect that my eye is playing tricks on me ..

Back home looking at the big screen .. looks good as what you all are seeing .. but it all seems to be riding on a thin line .. a little here or there .. bang .. HOT SPOTS !!!

Nikon 10-24 .. looks good ya .. also the most ex of the lot .. actually cost about the same (slightly cheaper) than the 12-24 :sweat:

Guess I will have to give the N10-24 another run tomorrow .. hopefully the Sun is bright bright

 

[limwhow]

I tell you ah, LowLights.
I am being bugged top to bottom by the hotspots on my Tokina 11-16mm such that I am either considering testing it out on SereneXMM's ELP to see if the hotspot will go away, or I may at the end of the day no choice go and get another EF-S 10-22mm for my R72.
The Tokina 10-17mm Fisheye is not bad, but again, like all my Tokinas (haha.. no offence to Tokina users), it does give me the occasional hotspots.
I would really love to have in my hands a lens that I will never need to worry about hotspots.

I feel what you feeling .. yup .. one stupid lens to rule them all :bsmilie:

I think you should just get another 10-22 .. from what I see from the photos .. I am surprise that you have not made the purchase .. I would ..
How I wish someone can tell me straight in the face .. that N10-24 is THE lens ..
