What a coincidence.  There was a $15 "L" upgrade for your lens that was mentioned yesterday .  The results look spectacular.  Surely, this would be your first option.  :)

I think your photo looks fine.  The "1864" is visible.  Looks quite sharp (but being compressed, it's difficult to tell).  Just wondering where you feel it falls down?  Most Canon kit lenses should work fine for product shots.  You're generally shooting stopped down a bit (maybe f/8 or f/11), using a tripod and have full control over the light.  (BTW, if you're using a tripod, try turning IS off and see if that improves anything).  I doubt that a more expensive lens would give you noticeably better results.  If sharpness is the issue, I'd try moving back a bit and using a longer lens (at least be at the 55mm end).  For an object so long, if you're shooting at only 3 feet away, it would be difficult to get the whole thing in perfect focus.  Whereas, if you were three metres or further away, it's a lot easier.

Perfection is an ellusive goal.

Sir Frans Lanting started off with a mirror lens.  Didn't seem to hurt him.

I've got an old MF Minolta 400mm f5.6 lens that I connect to micro four thirds camera.  This essentially becomes an image stabilised 800mm f5.6 (in 35mm talk when you factor in the 2x crop factor).  Image quality is very good for a cheap-ish option.  But its not perfect.  In a lot of high contrast situations I get some noticeable purple fringing.  But with a 2x teleconverter, that's 1600mm and its still ok.  With two 2x teleconverters, you get to 3200mm and you can take some identifiable pictures of Venus and Jupiter (although they are still very small, and the image quality is ordinary).  I should buy some Canon teleconverters and see how the old lens with cheap teleconverters compares with a newer lens.   

I'd love for Canon to make an affordable 600mm or 800mm with autofocus.

If you're bringing back equipment over $1000, it is declarable and customs will try to charge duty on it if they believe that you purchased it new overseas.  To avoid problems, just complete a "goods exported in passenger baggage" form before leaving.

Canon, why do you insist on giving us cameras with either too few or too many MPs?  Wouldn't it be easier to just give us a camera with the optimal amount of MPs that will please everyone?

I'd agree that a middle of the road approach is generally better than a choice of cameras on both extremes. 

But I assume Nikon have done their market research.  Imagine a situation where you had a choice of three cameras - low light / allrounder / big MP count.  I'd suspect that most people would choose the big MP option.  Some would choose the low light option.  The allrounder would probably be a sales flop?

Don't forget the Canon 1V!

But I doubt that there will ever be a new, high selling, film camera released in future.  If anything, existing manufacturers will pull out of that market.  Therefore, I guess I'm referring to the 99.99% of future cameras that won't be digital medium format cameras.

But I agree totally with the comment above.  There will always be a market for a product that does one thing exceptionally well.  But given the ease with which video features can be incorporated into digital cameras, I just can't see any mainstream future camera lacking this feature.  And this feature set will continue to grow over time.

Lenses / Re: Dust, is it myth or fact?

The story of my 100mm macro... 

The AF-MF and the focus limit buttons fell off a few years ago.  I didn't think much of it at the time as I was able to change the setting using a pen or other sharp object if needed.  What I didn't realise was that this was giving dust an easy entry point into the lens.  My lens is one of the early versions where the barrels extend a lot while focusing. 

When I did notice a bit of dust inside, I wondered if blowing some air into it would clear it (or at least move the dust away from the centre of the elements towards the edges).  Turned out to be a bad idea - a lot of dust had been sucked into the lens through the hole but hadn't yet made it onto the elements.  By blowing air into it, I ended up distributing a lot more dust over the elements.  When I saw what I had done, I was very disappointed.   But I still use the lens a lot and if the dust is causing any image degradation problems, it's not obvious to me.  I sometimes feel the photos lack saturation, but it could just be my imagination. 

Sorry about my anecdotal story, but I just had to warn everyone.  Blowing air into your lens to move the dust off the elements will probably make matters worse!  Who'd have thought that?  And to Canon - why can't you build decent buttons?

So, dust in lenses?  With an easy entry point, these things definitely suck in a lot of dust.  But if it is reasonably sealed, it's probably not much of an issue.

Is it a problem?  You'd have to have a lot of dust in there for it to be a problem.

If it's f/2.8, it's not fast enough relative to the 24-105mm f/4 for me to really consider it, and I'd wait for the Samyang 24mm f/1.4 to be reviewed.

Smaller, lighter, cheaper, faster, reduced minimum focus distance, possibly better image quality.  They've definitely got some positives.  I say, "well done Canon!" for giving these guys an update.  They might not be everyone's cup of tea, but I'm keen to read some reviews on the 24mm. 

In their respective price brackets, I also feel Canon's offerings are as good (if not better) than their competitors.  Plus, one of the consistent reasons in the "Why Canon" thread related to Canon's extensive lens range.   Why would Canon be making lenses for people they hate?

I'm not going to pretend that Canon is perfect (ok.... they are perfect - I'm just being diplomatic), so why not be a bit more specific in your criticisms?  If you don't say exactly where Canon fails to meet your expectations, then nothing is likely to change.

I change my mind daily.  Today I'm thinking: -

Canon 1Ds Mk ii - $1,500
Canon 135mm - $1,000
Canon 17-40mm - $700
Canon 50mm - $100
Olympus OM-D and kit lens (the leaked photos looks cool!!) - maybe $900??
Olympus 45mm and 75mm (assuming rumours are true) - another $800??

Ladies and gentlemen, I give you the Canon MEOS 1, with EF-M mount, 40MP 45*30mm sensor with a fixed pellicle-mirror...

Excellent thinking!  Welcome to the design team!

In relation to the number of lenses...

My Mamiya 6 only has three lenses - 50mm, 75mm and 150mm. 

The more popular Mamiya 7 has six lenses - 43mm, 50mm, 65mm, 80mm, 150mm and 210MM

There were about 20 potential lenses for my old Mamiya RB67, including tilt-shifts and macros.

It needs a square sensor, too.  Make it 45x45, then if you want to crop down to 45x30, you can.  Lets make it EF-S compatible, too.

I think you're spot on with the burst rate.  It should increase as the crop size reduces.  Want 7D performance, just flick the switch to APS-C.

If only Canon would let us design their cameras....

Sure.  Why not?  Most medium format lines only have a handful of lenses, anyway.

BTW, no need for "expensive ultra high quality lenses".  A bigger, better sensor would be enough. Reasonably priced lenses would be more than sufficient.  And let's make it with an EF mount.  That way, when regular EF lenses are attached, the camera reverts to a "full frame" camera.  And when it detects EF-M (ie specific medium format lenses), you can use the whole sensor.

I'd also have it so that you can use the EF-M lenses on other Canon bodies (so you can take a 7D, for example, as a backup body).  EF-S lenses aside, everything in the Canon line-up should be compatible with each other.

Not technically Canon related, but the Pentax K-01 is to be announced in a few hours.  It's designed by an Australian - Marc Newson.  He even gets his name printed on the camera.
