Pros: Size, Weight, Cost on wear, Sew, keeps AF

Cons: AC (on sigma 105 macro in TA at f4 visible in backlight), AF calibration (sigma 105 2.8 to f4 with lightweight TC back focus, d5200 can not be corrected), slight decrease in sharpness and contrast.

Opinion: Taken after the sale of the canvas to be used on the sigma 105 2.8 stabilized macro of the same series: it is compact and weighs little, keeps the automatics on the sigma 105 macro (running af 0.45m at infinity) but unfortunately on my D5200 light back focus (I will probably use it to f8 on moving subjects or manual focus in portrait); At the level of yield loses detail in any case since the lens is less contrasted in the portrait with TC I find the most pleasant (less sharp) yield, otherwise the blur remains the same; At a bright chromatic level AC in backlight or strongly contrasted to f4, which is attenuated by diaphragming the lens to at least 5.6, inevitable I think using a TC, otherwise the lens is less contrasted and with less microcontrural but still of excellent quality ; Macro side at the same focal distance of fact from a 1.4: 1 magnification, allowing for a greater distance for 1: 1 shots, at maximum magnification at equal apertures I did not notice any major leak loss, I would say the lens behaves pretty much Well permittingTo blur better the background, I will test the yield in the next few days with this use, especially in terms of AC using flash on insects with shiny body parts; Probability on dx format has a worse impact than the FX format, on the other hand at the same focal point as my sigma 105 I think is much better than what I saw on my old tamron 70-300 VC USD, as soon as I can buy a 180mm probably I will sell it, so far it is a good handbag if needed.

Pros: Excellent construction, with a solid feel. Value for money.

Cons: Anything.

Opinion: It is a good teleconverter, well built and solid. The use often combined with Sigma 105 macro 2.8 and 70-200 2.8 HSM stabilized, with excellent results, with both the Nikon D7100 that with the D750, without detecting the decay of the images. The minimum weight and bulk invite me to always take it with me when hiking in the mountains.

Pros: Price, value to be used, quality and automation maintained

Cons: if we want to find backward compatibility, but not with all the bodies ....

Opinion: I have this multiplier to un'annetto around and use it with most of my paintings, and Sigma 70-200 L canon 300 F4 Apo HSM. tried both on 5Dmk2 that of 60d, allows you to do things (though not with the same quality) for which you'd need to super telephoto ... for people like me do not need optical tropicalized hs is a must have ... Also in bag when you go hiking or photographic walks in the woods and countryside ....

Pros: quality / price great, keeps all the automatic

Cons: not yet found

Opinion: use with 70/200 2.8 sigma in aps-c fabulous, also tried on Tamron 200-400 f 5.6 saves you seen the Focal which arriva.Sono satisfied lightweight, inexpensive and tantissimo.Ottimo I might compromise a long focal length with limited spending, certainly does not have the quality of 400 mm nikon, but with saving money I'm on vacation and fotografo.Consiglio purchase

Pros: Image quality price

Cons: At the moment no

Opinion: I use coupled with the canon 180 f / 3.5 macro and Canon 70-200 f / 2.8 II is and I must say that I was not at all disappointed. On Canon eos 1d mk 4 autofocus is handsome without loosing speed. The image quality is very high without chromatic aberrations diaframmando of 2/3 stop. Stands midway than kenko and the canon / nikon. Advised

Pros: Compact, price

Cons: Lack of tropicalization

Opinion: I took the multiplier Sigma 1.4x EX DG to mount on both Sigma and Canon lenses. I've often used with Canon EF 500mm f / 4 L IS USM to get to 700mm, I compared it with the Canon EF 1.4x II provided by a friend, to my surprise I noticed that the photos remain substantially the same as sharpness. If you are looking for an excellent low price multiplier giving the tropicalization, Sigma 1.4x EX DG for you!
