The Tamron 24-70! It can double as 112 mm f/2.8 lens on a crop sensor too.

I don't even bother with DxO reviews or tests anymore because they often totally contradict other reviews.

I have all the gear I need now. ... Said no photographer (or keen enthusiast) ever.

I think we recently discussed this in detail already:

Lenses / Re: New 35mm f2 IS - Potential mount issue?

Try freezing your lens before mounting it, that will shrink the metal and give it more tolerance. Of course the mount may seize up when the metals of the lens and the camera mount reach the same temperature  ;D ;)

EOS Bodies / Re: A New Rebel for CP+? [CR1]

I wonder which part of the existing Rebel has been 'improved' so that it may be sold as a 'new' Rebel  ::)

Hands on: Sigma 50mm f/1.4 Art ignores Canon L, Nikon glass and targets Zeiss Otus. No, really.

Go Sigma, Go!  8)

As you can see from my signature, I'm a fan of Sigma at least in regards to their wide to normal lens line-up. I wonder if I'll be able to resist the new 50 if it really turns out to be that good...

I think it would perhaps have been more accurate to say the vibration a grip permits, if you want to check, try flexing the camera with grip, vs the camera without grip when attached to a tripod, you will find significantly more flex with grip than without, this would translate to vibration as it is obviously less rigid.

Indeed, that's a much better way to phrase it - thanks!

Interesting, but being a 99.99% handheld shooter I think I'll be okay with my grips :D

Canon EF Zoom Lenses / Re: Canon EF 100-400mm f/4.5-5.6L IS USM

I took this lens out last weekend with my new 5D Mk III to get a feel for this combination, and here are a few samples. Interestingly I hadn't thought of this as a landscape lens before, but now that I do, it opens a whole new world of possibilities :)

Dear my friend mrsfotografie.
I love your fantastic Tricks that make me feel good, and you feel happy too.
My Trick are simple---Every time that I go to buy the new Photographic equipment from the Local Camera Shop, or Order from Internet---I must buy the Jewelry/ Diamonds/ Lady's Decor. Items for my dear wife, which cost 25% more than my Equipments----Ha, Ha, Ha---That Why, She still love me, Not Kill me yet---So far. Plus, She is the Vice President/ Book Keeper/ CPA of my Company----She Know that , When I want another Big White Lens that cost more than the her 3 Carat Diamond Ring---Yes, Now she might want 5 Carats -Pure White Diamond Ring---Ha, Ha, Ha--YES, That will save my family life. Yes, I tell her that Canon EF 800 mm  will use for the Office Job, That I can shoot the Top of Building Details/ Architectural Detail with out risk my Life to climb the Building , and use Old 50 mm. Lens-----Ha, Ha, Ha.
Nice to talk with you.

That's very funny Surapon, and I think those rules work across all cultures.

There's also the special case that seems to be a Thai exclusive, when I was a very young soldier I was enamoured of a very Lovely Thai Lady (are there any other types ??), she clearly pointed out to me what happens when anything comes between her & her love/interest for you, they arrange for a duck to eat what's left of your Family Jewels, generally this applies when your interest might momentarily shift to other young ladies, but Obsessive Camera interest always concerned me as a possible cause, so I sold all my Cameras during this interlude.

Fortunately I must have read the situation right as I'm now the very proud father of two growing sons, and everything is still where it's supposed to be, mostly.

This might be the ultimate reason for your very fair attitude where your lovely wife is concerned.

LOL, I'm happy to say my private life isn't quite that dangerous ;)

I'm still trying to figure out which one of these AF chips to buy on eBay.  They all appear to be the same thing, but prices range from $4.15 to $38.99.  Descriptions and prices include:

  • New Optix V6 AF Confirm PCB Chip for Canon EOS ( Can Store 3 Lens Config) $38.99
  • New Optix V5+ AF Confirm PCB Chip for Canon EOS $28.99
  • AF Chip "Dandelion" for Canon EOS. Origin EMF chip made by Victor Lushnikov $23.98
  • *EURO* ETTL AF Confirm EMF Program Chip for Canon EOS 5D Mark3 MkIII 6D 600D 50D $22.77
  • EMF AF Confirm chip for Canon EOS EF camera $10.93
  • New generation easy install AF Confirm chip for canon + EXIF EDIT with installer $7.15
  • AF confirm chip chipset for Canon EOS EF lens adapter $4.15


I'm interested in the chip that will provide the most features and functionality.  I'd be happy to spend $39 instead of $4 if the more expensive chip had advantages that are worth $35 or more.  Any suggestions appreciated.

I purchased the "dandelion" chip myself.  It gives you quite a bit of functionality.  Programming it via the camera is a little awkward, but can be done.  The primary thing I wanted was not the focus assist aspect (I find the combination of prefocusing at more narrow apertures and then using live view x10 at wider aperture a more sure bet), but it was important to me to get some a reasonable EXIF data for cataloging, as I have other lenses that also don't report EXIF data and there are times that I want to sort my work by lens.

The top one I would only use for an adapter because if you glue the chip onto a lens, it requires setup for one lens only.

Get an EMF chip. Mine has the following specs:

Chip  EMF type.
1. Lens maximum aperture can be programmed from F/1.0 to F/45
2. Focal length an be programmed from 1mm to 65535mm
3. Focus micro-adjustment possible in steps from 0 to 31.
4. Data is saved in the chip.
5. Supports AV and Manual modes.
6. Exposure data can be saved in EXIF.

And this is how I programmed it:

Samyang 14 mm: 14mm F/2.8, Micro focus adjust 26


1 Turn camera on and attach adapter with chip,aperture shows F1.4 on camera.
2 set Manual mode.
3 shutter speed to 1/60 second
4 aperture increment step to 1/3 EV. (it is the most Canon digital camera default setting).

set the aperture value to F/64 and press shutter button once.
set the aperture value to F/57 and press shutter button once.
set the aperture value to F/64 and press shutter button once.
Turn the aperture dial, set the Max aperture to F1.0.

For example: 14mm f2.8 micro adjustment 24

Enter  programing mode: F64 shutter, F57 shutter, F64 shutter

Setting focal length

Setting focal length mode: F2.2 shutter

Enter focal length value:  F2.0 shutter F2.0 shutter F2.0 shutter F2.2 shutter F3.2 shutter (00014)

Store parameter to chip: F57 shutter F64 shutter F57 shutter

Focal length setting done to 14mm.

Setting Max aperture

Setting Max aperture mode: F2.0 shutter

Enter Max aperture value: F2.8 shutter

Store parameter to emf chip: F57 shutter F64 shutter F57 shutter

Max aperture setting done to F2.8.

focus micro adjustment

Enter programing mode: F64 shutter, F57 shutter, F64 shutter

focus micro adjustment mode: F2.5 shutter.

Enter focus micro adjustment value: F2.5 shutter F4.0 shutter.

Store parameter to emf chip: F57 shutter F64 shutter F57 shutter

Micro adjustment setting up done as 26.

I somehow always have another lens on my mind  ::)

Take it from me - getting a 1D X won't cure you of that desire...   ;)
How disgraceful, you guys have no self control ... may I join the club  ;D
Neuro is right. In fact not having enough liquid cash also does nothing to cure it  ;)
Very true! ... I remember reading "photography being a more serious addiction than alcohol or drug addiction", coz a photographer is more likely to live longer than the boozards and druggies  :) ... my wife often says (about me) that if I had my way I might even sell the house to buy new gear ... sometimes I scare myself coz those thoughts do cross my mind. :-[

Well I wouldn't go all the way to selling my house, but I often trick myself by making money seem twice the value. Here's how that works:

1. Find a camera product that you really desire and is expensive (easy to do).
2. Justify the purchase by saying to yourself that you will be able to sell the product/products you're replacing at a good value.
3. Purchase the new product before you sell the old one because you think you need to make sure you are actually happy with the new one and/or don't want to have a period of time where you don't have the product available.
4. Decide not to sell at all, or worse:  Justify yet another purchase by saying to yourself that you will be able to sell the product/products at a good value.

This is how I now ended up with three camera bodies. I justified the purchase of the 5D3 foremost because I think I deserve it, but also by selling my last crop lens (Tamron 17-50) and promising myself to sell the 7D (I am not selling the 5D2 at all). Now I want a 70-300L and I think the money I can potentially get from selling the 7D (and Tamron 70-300) can be put towards that lens, so that then really justifies that purchase...  :o ;D ::)

When I had a 7D and 5DII, the grips were always on them...except when shooting critical shots from a tripod. I like not having to remove the grip to eliminate the extra vibration it causes.

Interesting, never thought of that. I used a battery grip on the original 5D because it boosted the shooting time from a set of batteries so much. However duration of the latest single batteries is so much better I don't bother with a grip on the new bodies, but I'm not using very large lenses.

I have almost never shot with two batteries in the grip... still all my bodies are gripped for handling's sake. When I travel, the grip comes off. When I take two camera bodies, one of them is likely to have the grip removed to save space in my bag. Invariably the body with the biggest lens gets the grip.

I've always found the body size needs to match the lenses.

Absolutely. And this is especially true when handling the big lenses. The only reason I will add a second battery is to balance the set-up. I did that only when I still owned a 40D and a Sigma 150-500. Since I sold the Sigma, my biggest/most front heavy lenses are the 100-400 and 70-200 II but they balance fine on a 5D2/3 or7D with a grip and a single battery. I also no longer have a 24-70L partially because that is the worst balanced lens I ever used - it becomes incredibly front heavy when extended, and because that is at the wide end, that is also most of the time.

I'm fine if Sigma copied the best 50mm lens ever made.
"Imitation is the sincerest form of flattery."

I think it's too strong to say that Sigma 'copied' Zeiss. Manufacturers keep an eye out for technology from the competition and try to learn from them as well, but 'copying' is generalising too much. Sigma has incredible lens-design know-how (it is their core business!) and recently they decided to up the ante - and also the price of the new products. It's not as if Sigma suddenly became better at lens design, it's the way they approach the market that changed.
