TS-E 24mm f/3.5L with TC 1.4x

[outoffocus]

I read in a review somewhere a while back that this lens works with the Canon TC 1.4x extender.. I cannot find and data on this combo on the Canon site.

Anyone out there have any experience with the two? I have the extender and am thinking about getting the lens.

thanks in advance!

Hi Outoffocus,

The following was from canons EF lens website

Extender EF 1.4x II
This tele extender can be used with fixed focal length lenses 135mm and longer (except the 135mm f/2.8 Softfocus lens), and the EF 70-200 f/2.8L, 70-200 f/2.8L IS, 70-200 f/4.0L, and 100-400 f/4.5-5.6L IS zoom lenses.

It sounds like its a no go, but I will check once I get home.

Best regards

Yes.. let us know Bear... I might have to edit the T-con sticky if it works...

(that would be weird if it does work)

Hi BearSummer,

Thanks for the effort! Look forward to hearing your answer.

This is the quote and review from another site (photographyreview. com).

Summary: If you have a Canon line-up and shoot architecture, there's nothing else to choose. The TC1.4X worths considering. With the TS24 and the TC, you virtually have two lenses of correct perspective (24 and 35, lovely focal lengths) for less than $1,500.

Strengths: Tilt and shift capability; Fairly good distortion control; Good optical quality considering its huge image circle; Auto-aperture (The only auto-aperture shift lens in the market); Works with TC1.4X (Though not officialy by Canon)
Weaknesses: Bulky; Pricy; No auto-focus when not shifted/tilted"

I do believe that the 1.4x DOES phyiscally fit the TSE lenses but I cannot for the life of me wonder quite what the quality is on a 24mm as the Canon Extenders are surely computed for use with telephoto optics (100mm on the 100-400 being the shortest focal length). Perhaps the TSE lenses are exceptions to the rule.

Along with the 70-200 lenses... :wink:

Just teasing - I would also think that the 1.4TC wouldn't be a great optical match for the 24mm TS.

Thanks for that Scottes!

Just looked at the Forum time and we are another hour ahead of that anyway - it is nearly tomorrow.

Hi Outoffocus, et all,

just checked the 1.4x with the 24,45 and 90 and the good news is that it fits all of them, it looks a bit tight on the 24 but its just short of the rear optic so we should be ok. As to quality of image i didnt get a chance to shoot anything tonight, sorry

best regards

If it's tight, what would happen if you used any tilt? I'd be concerned that you might have a collision, and that's one mighty expensive chunk of SiO2.

Uh? Do they actually use SiO2 in lenses?

I thought it was new space technology ground from a crystal ultra low dispersion secret stuff... :?

At least in L lenses

[Jon]

Last I looked, glass was a primary ingredient in most lenses, and that's mainly amorphous SiO2 ;{)#

In many telephoto "L" lenses there is a single or at most two "Flourite" lens elements... this is the "home grown crystal" that you are thinking of.

In a lens like the 100-400mm out of over a dozen elements, only one is Flourite.

[DocFrankenstein]

I see... So they artificially grow the crystal and then grind it? :?

[Jon]

Unless you want to be still more hopelessly confused, let's just say "yes". The stuff they use in lenses has a not dissimilar relation to CaF2 (crystalline) as optical glass has to quartz.

That's the meaning of life. Get really confused and die. :D

[Jon]

Ok, here goes . . one step at a time . . .

You know, of course, that glass isn't really a solid, more an extremely viscous liquid, right?

yes

[Jon]

OK, and to get different indices of refraction, they "salt" it with various impurities . . .

Here is a link that you guys might find interesting:

Virtual Lens Plant (http://www.canon.com/camera-museum/tech/l_plant/f_index.html) in the Canon Camera Museum.

It explains how Canon makes glass and lenses.

.. just kidding.. i know my post holds little relevance to most .. and .. i love this board.

Bearsummer, thanks for the info. Are you going to try shooting a few, or leave it there? (i still can't believe you own all three TS lenses!)..

thanks again!
