Default 40D and L Glass

I picked up my 24-105 F4 L from the shop this morning. I actually had to pick it up twice as the first lense had a problem with the image blurring on the extreme right hand side (only really showed up at full size in Photoshop, but I couldn't live with that. For that price you want perfection).

I've been playing around shooting stuff all morning and all I can say is wow, the quality is stunning. Working from a TIFF produced by DPP from a RAW file, zoom in at full size in Photoshop and there is absolutely NO degradation of image quality. I've hardly had to apply any unsharp mask or noise reduction with Noise Ninja.

Can't wait until I can try it all out on a railway subject - hopefully this weekend if the weather is good.

Thanks to the forum for all the help deciding on a 40D and this lense.

Good for you, If i had the cash , that was what i was getting. but settled on the EF 24-85 3.5-4.5. Photozone test showed it to be a good buy on a 1.6 camera and it is sharp. I had 17-35 covered so not missing the wide end. with your first post with it put it on here so we can give it a good look.

I like my 24-105mm I'd say 90% of my photos on the site were taken with it. I have started to notice some dust under the front element so Im plannign to send it into Canon. Enjoy the lens, I hope to get the 40d sometime this yr or maybe the new 5d

If you want a old 5D Canon just dropped it down to $1800? so a new one must be in the works soon.

I'm glad to hear that your new lens is working wonders, Steve. My mate uses one on his 350D and you can tell the difference between an EF and and L (especially on cloudy days and low-light conditions).

I look forward to seeing your first accepted shot.

As promised here is the first photo accepted using my new 40D.

Sorry its not an especially exciting composition, but this is rare preserved traction visiting one of its old stamping grounds and as it doesn't happen too often I wasn't taking risks.

This is also the first photo where I've made use of layer masking having found out how to do it properly after reading a photographic magazine article. The sky has been darkened to bring out the detail down near the horizon, the canal lock on the right has been lightened, the water darkened slightly to show detail and the loco front has been lightened so that the buffer beam detail isn't just a black shadow.

Thanks - the only area I had issues with was around the cab front. I had to be careful defining the area masked off and how much I blurred the mask to avoid halos appearing on the surrounding image.

I'm amazed at how noise free the captured images are, ISO 400 will be easy and 800 should be possible with careful processing.

Still getting that illegal IFD offset on the EXIF data, must be how I'm processing the pictures.....???

Sounds similar to what I get. I'm processing RAW to TIFF, then into Photoshop 7.0, then TIFF into Noise Ninja, then JPG out.

Some of the earlier shots with my Fuji S9500 were recorded as JPG's in the camera which were taken straight into Photoshop, then the same workflow - EXIF data looked fine on RP for those.

Does TIFF have an EXIF capability? Is it updated to the latest standard? Maybe having TIFF in the middle of the workflow mucks things up. Just speculating.

Thats what I think TIFF is mucking up the EXIF data somewhere - I have that EXIF util (Opanda IEXIF ?) on my home PC. If I right click on the picture in RP it shows the EXIF data fine.

Matt took a great shot, just don't like the way the shot turned out. I think he over did it in PS. I didn't think we can do that to a shot. And Raider we are just talking about it, not cutting his hart out.

The real amazing thing about this post is...how in world does a person pay as much as you do for the 24/105 L...and get a bad copy. One would think careful inspection of every aspect of a lens would be part of the big price you pay for one of 'em.
And it ain't just Canon, either, I see on some of these photo forums that Nikon does this once in a while, too.

I'm not the only one regarding the 24-105. Alan Crotty told us a while back that he went through 3 before he got a good one. After reading that I made sure I tested it thoroughly as soon as I got home.

Hi Steve,

Pleased to hear you found a good 24-105, it can be a really nice lens and so versatile too.

Ref you EXIF issue with TIFF, can you detail out your work flow?

I know that some programmes do destroy part of the EXIF.

Maybe as simple as it was dropped hard in shipping, Think some lens's may be more touchy, Wide to long zooms have more moving parts, and wont take a drop well, as they have more glass and hit harder. Nikon's or Canon's best still need to be handled right to keep them sharp. I don't think they would ship a bad one do you.

Hi - thanks

Workflow is as follows
1) Convert RAW image to TIFF file using DPP, adjusting white balance and exposure if necessary
2) Load TIFF into Photoshop 7.0. Adjust levels, contrast etc etc, apply Unsharp Mask, resize and output to another TIFF file
3) Load TIFF into Noise Ninja, de noise as appropriate and apply final sharpening. Output to JPG file

I don't think they would knowingly ship a bad one, and I'm sure they have quality control procedures in place during the manufacturing process.

The packaging of the lense could be improved to give better protection in case of the inevitable rough handling during bulk shipment.

Lenses, even those costing 10's of thousands, are delicate instruments. If the mount is off a few 1/10,000's of an inch or the internal focussing cage gets out of alignment, you get soft images.
I'm not familiar with high-end still lenses, but very familiar with high-end cinema lenses. The multi thousand dollar lenses are checked out at the camera rental facility before shooting begins and monitored during the job. Sometimes the Angenieux or Panavision lenses were out of alignment and where no good to shoot as they were. It is then sent to the facility's service technician who put them on the collimator, the MTF machine and the projector. If shims were needed, they were installed in the mount and the lens retested. It is a common procedure.
I would think if you get a screwed up lens, return to the store to get another or send in to Canon or Nikon for service.
The more expensive the lenses are, the more hand built they are. Which is not unlike steam locomotives. Sometimes you'd get one that centers on spec and is fantastic. (if a good design in the first place) Sometimes you get the same model but made on the edge of spec and the lens is soft or the locomotive is a hard steamer.
Crap happens unfortunately, even at high prices.
