  • Canon EF-S 17-85mm f4-5.6 IS USM Lens Review
    to the front filter mounting thread of the lens Filter size is 67mm Canon EF S 17 85mm f 4 5 6 IS USM includes a second generation Image Stabilizer which could help you gain up to three f stops when hand holding the camera The auto focus is quite fast and silent The factory box includes Canon EF S 17 85mm f 4 5 6 IS USM lens front and rear lens caps manual and a warranty card The lens accepts EW 73B lens hood sold separately You can also use LP1116 soft case also sold separately The lens is compatible with Canon s extension tubes EF 12 II and EF 25 II You can also attach gelatin filters to the lens using Gelatin Filter Holder IV at the expense of the lens hood which cannot be used with the holder Summary Lens Composition 17 elements in 12 groups Angular Field 78 18 degrees Minimum Focus 35cm 1 15ft Focusing Action AF MF USM f stop Scale f 4 f 22 camera controlled Filter Size 67mm Lens Hood EW 73B optional Weight 475g 16 8oz Dimensions 78 5x92mm 3 1x3 6 Lens Case LP1116 optional Field Tests Canon EF S 17 85mm f 4 5 6 IS USM showed average overall results The lens is very sharp in the center but the border quality is unimpressive across pretty much entire zoom range The lens shows some noticeable barrel distortion when wide open Vignetting is also on a high end which could be explained by the fact that this is an APS C type lens with a reduced imaging circle Stopping down to f 5 6 or f 8 helps reduce vignetting The lens also showed pronounced chromatic aberration primarily around 17mm to 35mm While disappointing it s not the end of the world since chromatic aberration can be corrected with a variety of post processing tools IS is a great addition in this lens and helps you gain extra 2 3 f stops when hand holding the camera a much needed feature for this relatively slow lens Many would argue that the main benefit of this lens is its versatility since the lens covers a pretty aggressive zoom range That would have been the case if the lens did not stink in the wide zoom range Title Title Title View the embedded image gallery online at http slrlensreview com web reviews canon lenses canon standard zoom 30 canon ef s 17 85mm f4 56 is usm lens review sigProGalleria6f50e26fac Lab Tests Canon EF S 17 85mm f 4 5 6 IS USM produced very mixed results The lens is really sharp in the center but the border quality is dismal especially at the wide angle Things get better in the middle range the lens is sharpest around 35 50mm but the quality degrades again towards telephoto zoom At its best the lens would produce good 11in prints 35mm FL You will still be able to get ok 16in prints

  • Carl Zeiss Biogon T* 35mm f/2 ZM (M) Lens Review
    67in and weighs 240g 8 46oz The aperture ring moves in 1 3 f stop increments with the min aperture at f 22 The minimum focusing distance is 70cm The lens accepts 43mm screw on type filters Biogon 35 2 can be used on all film and digital M mount cameras including Leica M8 M9 and Epson RD 1 It can also be used on Micro Four Thirds as well as Sony NEX camera systems using readily available third party adapters When used on M8 with it s APS H type sensor the EFOV of the lens is 46mm while when used on APS C type Sony NEX its EFOV is 52mm Within the scope of this review Biogon 35 2 was tested on Leica M8 Summary Lens Composition 9 elements in 6 groups Angular Field 64 degrees Minimum Focus 70cm 2 29ft Focusing Action MF f stop Scale f 2 f 22 manual Filter Size 43mm Lens Hood Metal optional Weight 240g 8 46oz Dimensions 52x68mm 2 04x2 67 Lens Case N A Handling If you re like me and still are using Leica M8 or M8 2 then Carl Zeiss Biogon 35mm f 2 ZM is going to be a candidate for a staple lens for you because of it s EFOV of 47mm it is my most frequently used lens right now Planar 50 2 comes close second But even if you re lucky M9 owner or even if you re shooting one of the classic film cameras chances are pretty high that a 35mm lens will find its way into your camera bag The question is which one For years Carl Zeiss has been considered the 2 in the modern rangefinder world This is despite the fact that the company has delivered more innovation in the optical world than pretty much any other company out there While many Leicafilles would be quick to point to facts like outsourced manufacturing and non cutting edge lens designs i e footprint lack of aspherical glasses etc I think Zeiss is a pragmatic company and simply decided to target different segment of users users who can t or don t want to spend obscene abounts of money on a lens and who would be happy with 90 95 of the capabilities of the thrice more expensive glass offered by Leica And Biogon 35 2 follows this concept very closely What is puzzling however is why did Zeiss decide to offer two 35mm Biogons In addition to the 35 2 version the company is offering 35 2 8 variant The price difference is not that significant US 150 to think that the slower version is targeted for price conscious users like Leica s Summarit lineup The 35 2 8 Biogon seems to be following the original Contax Biogon design while the 35 2 Biogon is an updated more complex formula I have not had the opportunity to own or test Biogon 35 2 8 so the answer to this question unfortunately

  • Carl Zeiss CP.2 Distagon T* 35mm T/2.1 ZE Lens Review
    80s and 90s The current generation of CP 2 lenses was specifically adapted for the use on modern HDSLR cameras and have interchangeable mounts giving users the flexibility of using the same lens on multiple camera systems including Canon Sony Nikon and MFT CP 2 series are also the most affordable cine lenses in Carl Zeiss current lineup with the CP 2 Distagon T 35mm T 2 1 ZE priced at US 3 900 Don t get fooled by the name Compact Primes it might be compact in the world of cine lenses but not in the SLR world The lens weights 1kg 2 2lb compare that to say Master Prime Distagon 35 1 3 which weighs 2 2kg and you would realize that this is really compact The bulk of that weight goes into housing fully metal with superb overall construction The lens has conical shape with very wide front designed to accept 114mm matte box The lens measures 80 x 115mm 3 15 x 4 52in The optical construction of the lens consists of 9 elements in 7 groups The minimum aperture level is T 22 and the minimum focusing distance is 30cm 12in Within the scope of this review the lens was tested on a full frame Canon 5DMk2 The lens can also be used on APS C type HDSLRs like Canon 7D or with the appropriate mount on Nikon Sony and MFT cameras Summary Lens Composition 9 elements in 7 groups Angular Field 64 degrees Minimum Focus 30cm 12in Focusing Action MF f stop Scale T 2 1 f 22 manual Filter Size 114mm Lens Hood N A Weight 1kg 2 2lb Dimensions 80x115mm 3 15x4 52 Lens Case Custom Pelican case Handling Let me start with a fun observation about the CP 2 Distagon 35 2 1 the lens is a dude magnet Yes you heard it right show up with this lens in public places and you are guaranteed to be stopped at least a couple of times and asked about what that lens is why is it so bulky why does it have such a large front etc On top of that you will also have dozens and dozens of people simply looking at you with curiosity trying to figure out what exactly you re doing When I think about it this lens actually attracted more attention than the Canon 500 4L which is a much longer lens And so if you re hoping to take some candid pics video you might has well forget it if you re using this lens If this is the first time you re handling a dedicated cine lens it certainly was for me you will be surprised by a couple of thinkgs Firstly the lens if fully manual Well that was not the surprise actually but whatever Both focusing as well as aperture control are manual Focusing is super pricese I am not kidding you the ring rotates for 270 degrees which you can find in
