Review 1 of 3

Price Paid:  $175.00 from Ebay

Summary:

Got this lens a year ago. This lens has a good range as compared to the 50mm F1.7, which actually give an effective range of 75mm - only suitable for portrait. Whereas this Quantaray provides an effective 35mm wide angle coverage. Sharp pictures and good colours. This is essentially my regular lens, mounted on my Alpha body. The focusing noise is not particularly noticeable to me, perhaps I am shooting outdoor most of the time. I would say for a fast prime lens, this lens is very underated. There is not many available in the market too.

Review 2 of 3

Price Paid:  $150.00 from Jessops UK (£100)

Summary:

This is almost indistinguishable from the Sigma 24mm f2.8 which is no longer available. It is clearly of the same materials and its optics are identical. Quantaray have done this with several 'old Sigma' lenses. This is in no way bad because the optics are incredibly sharp for the money. NOTE the grindy chewy motor is perfectly normal, although its probable the long term wear and tear of this kind of motor, as opposed to 'newer' quiter ones is adverse to the life of the workings. I have yet to experience anything like that sort of problem though.

Strengths:

Incredibly Sharp (photodo 4.2 out of 5, Small, Lightweight fairly sturdy build also.

Weaknesses:

Slow AF, Commonly Loud Grindy Motor (normal for the rubberized Sigma/Quantaray of this range and as one user already stated its not a high speed/wildlife lens so who cares :D )

Similar Products Used:

Quant/Sigma 18mm f3.5, Cosina 19-35mm

Customer Service:

Sigma UK were amazing, they put me in contact with the only dealer who sells the exact hood for this lens. A*

Review 3 of 3

Price Paid:  $200.00 from Ritzcamera.com

Summary:

According to Sigma, this is optically same as Sigma 24mm f2.8. Though equivalent Sigma lens has been around since 1995 and priced at $200 or less, I chose this over Sigma because it is compatible with Canon EOS Elan 7. The AF is slow and it makes grinding sound but I use it for landscape or close-ups so I don’t mind slow or noisy AF. It is compact, light weighted sharp prime lens to own. The gold ring looks a little cheesy but the base of lens that is close to camera body has some nice designing that makes this camera classy. Other pros include: 52mm diameter, same as Canon 50mm f1.8. small enough to use with built-in flash. Smooth manual focus ring. DOF window that are not found in 50mm f1.8 II lens.

Strengths:

Better looking than Sigma 24mm f2.8 in my humble opinion. Canon EOS 7 compatible.

Weaknesses:

Wow, this is a loud AF lens. I hope it is not grinding or anything. Yah, AF is slow and it haunts.
