Hi Guys,

I am looking at a 40D package, and everything seems perfect, except the seller has just sent me a picture of the 55-250 lens.

I can't see any problems on the output pictures it produces, but are the specs on the lens a problem?

The seller said he has never noticed them as he has always had a polarising filter on the lens.

Thank you for any advice.
 
Its not just dirt or wet marks is it? or has he confirmed it is not that?
 
looks like dried water marks or insect residue to me. a drop of lens cleaner on a lens tissue should polish it up like new.
 
To me most of the looks like it is on the outside of the front element but I could be wrong.
 
ask the seller to clean the lens and send you some more pictures. I think you will find they go away..

I'm not sure if the guy has any lens cleaner, is there anything else I can suggest to him to try to wipe it?

So you guys think it could be good to go?
 
Tell him to glunk it into a basin of water with loads of fairy liquid :thumbs:
 
Thats not your problem.. He is the seller and if he wants to get a sale at the right price he will represent the lens in good condition.

If he wont then they are scratches so just walk away.

Pete
 
Ah, that's a shame, as this is the 40D, not the 450D.

Hopefully they will wipe off, but if not, should I let this go?
 
Aint that just the lens coating with those spots :shrug:
 
Like others have said it looks like water spots. I've had them on my L glass. If the offer is a good one go for it, you will be able to get rid of those with a little boots spectacle cleaning solution on a microfibre cloth.

Whats he / she asking ?
 
All joking aside, if you have any doubt and you can't physically see the lens for yourself then just walk away. It's up to the seller to present his wares in their best light. There will be others that will be on sale, there always are.
 
If he's used a flash they tend to show up specks of dust that you don't notice like house bricks on the photo.
 
I have asked him to see if he can clean it, and he said they are still there after using a lens cloth.

He has guaranteed me that they are not scratches, and he suggested himself that they look like imperfections on the lens coating. Is this bad?

He shown me a few images with the lens, and I can not see any problems, he is sending a few more so I will show you when he shows me.

£500 for a 40D, with a couple of filters, a CF card, a 18-55 and a 55-250

Everything else is perfect condition.

Good deal?

I'd say so, the 40D's alone go for about £400.

Let me know his info if he wants to split it down, I'll haggle on the the 40D ;)
 
If it is imperfections on the lens coating, will this be a problem? Or should I just snap the guys hand off at this deal?
 
That really depends on how it effects the images from the 55-250, if at all. I'd say for the rest a fair price would £450ish so assuming you don't mind taking a chance I'd say it is still a good price. I'd be tempted to haggle a bit though but that's just me being greedy ;)
 
Hi Guys,

The guy has just got back to me.

I have attached a single photograph of the lens zoomed in at 250mm at
f32. No "dust" specs appear in the image.

The lens at 55mm it not so good. The zip file contains five images at
different apertures. At f5.6 and f8 you cannot see the "dust" specs,
but at f16 and above they are noticeable.

On the images where you can see the dust, I can't really make them out.

Does it make sense what he has said? Would I need to use the 55-250 at f16 + when on 55? If so, surely I could just use the 18-55?


Sorry for all of the questions. It's just either this or a 450D with the same lenses for £60 less.
 
One thing to consider, when time comes to upgrade will you be able to sell the lens?
 
Okay guys,

I think I will leave it.

I did think I had a steal at £500 for the 40D, with 18-55 and 55-250, and a few accessories.

It's a shame really, as I was really looking at picking one up!

right, job done. Do you have his number? :lol: :naughty:


Edit- I wouldn't dismiss it really, still looks a good deal to me.
 
Craig can you get to look at the lens in person. It wouldn't bother me to have that on a lens you wont see it in the pictures.

It has nothing to do with the sensor.

No mate, I am in Manchester and he is in London
 
i get then type of spots all the time on my L lenses. they come off with a good clean with cloth or lens pen
the spots are dust on the sensor, they wont become visible untill you get to say f11 and above and are more noticeable with plain backgrounds such as blue sky etc,
oh and you could have them dust spots on a brand new camera body ,
infact id bet on it
 
Looks okay to me - just dust / dried water spot marks. As for the dust on the sensor, even if it's spotless when you get it, within a week, you'll have some - whether it's noticeable or not (probably not), but that's just the cost of using a DSLR - no biggie.

Looks like a nice price for a reasonable starter kit to me.

The dust he is seeing in the pics has everything to do with the sensor.
 
After speaking to a few members on here, I have gone ahead and purchased the camera and equipment.

It seems to be that the lens probably just needs a good clean with some cleaner, and possibly the sensor needs a clean, then everything should be fine.

I managed to get down to £480, so I think I have done rather well.

I just can't wait to get it now.
 
I think you have got a good buy. I doubt if you would see the difference on the photos even if you did not clean the lens front element.

Enjoy your camera and lens :)
 
Those marks are a negligible proportion of the lens area and will be very out of focus on the sensor. I'd be very surprised if you could see anything on the pictures.

If the seller can't clean them use it as a bargaining point.
 
In all honesty, the front element of the lens looks as if someone might have sneezed near it, no scratches or nasty stuff at all. A clean tissue and a dab of isoplopyl alcohol would clean that away no trouble. How to prevent recurrence? Stick a filter on it.
Dust on the sensor can (usually) be removed with a rocket blower like Giottos.

in my experience a rocket blower just moves the dust around the sensor. and if its grease spots, it wont remove it at all .
when you receive the camera, stop down to min app around f22 and fill the frame with a white wall or sheet of white paper and take a pic
dont matter what the shutter speed is or even if its in focus. you could usae manual focus and take it
open the image in photoshop and you will see the spots. but to see them better select auto levels and you will see the real extent of the dust problem

here is my sensor before clean last week. (auto levels)

all the rocket did was move dust around
and after wet clean

but if you are not a landscape photographer and rarely go past f8 you probally wont even notice any sensor dust
best not to dwell on it and just enjoy using it
