Need Help with a 7d lens equivalent to the Oly 35-100 f2

[akfreak]

Well I have been torn on what piece of glass to buy, I am looking for a lens that can take the place of my favorite lens the Olympus 35-100 f2. The Oly lens is everything I could ever of wanted in a portrait lens, it was the best lens I have ever used, and it is the lens I have made my best portraits with. OLY has a 2x crop sensor so it was a 70-200 f2 35mm equivalent. I can not find anything like that lens anywhere.

With the 1.6 x crop factor the 70-200 2.8 is too long and is a stop slower. I wish I could some how convert the 35-100 to fit my 7d but that is a dream. So I am looking for a zoom that can fill the shoes of my favorite glass.

I just got tired of Olympus always being late to the party with features like 1080 video, and High ISO capabilities, as well as fast frame rates and fast AF for sports shooting. I also know one camera can do it all. However I am hoping that I have missed something and someone knows of a f2 zoom lens that stays sharp wide open like the Oly offering.

Please dont jump all over me for talking about Olympus, but I really think they make some great glass. I am new to canon and new to APS. Please can someone show me the lesnes I need to be looking at. Thanks AFK

The only options I know of are Tokina 50-135mm f2.8 and Sigma 50-150mm f2.8.
They are both made for APS-C sized sensor and offer a very similar fov to a 70-200mm lens on a FF camera. Yes, it's a stop slower but with a bigger sensor, the depth of field may actually be shallower.

If it was me, I'd still go with a 70-200mm f2.8. Even on a cropped body, it offers a good range for portraits.

I cant say I am not just a little disappointed, I was hoping for someone to tell me of a lens I may of missed. It seems the 35-100 f2 is somewhat of a unicorn of a lens. I really like it, I was hoping there was an equivalent on canon. Thanks for your time, Akf

135 f2 L =P

Do you need it to be f2?

It's not a "unicorn" lens, it is just recreating 70-200mm range on 35mm/Full frame. With the sensor size differences, a 4/3 body with the 35-100 f2 provides the exact same DOF and noise as a Canon or Nikon Full frame body at f4 shot two ISO stops higher.

So the equivalent from Canon is the 5Dmk2 + 70-200 F4 IS. It even works out to be a lighter kit and about the same price as a higher end Olympus with the 35-100.

I'd agree, although the 35-100mm f2 Oly is a stop faster than an equivalent Canon/third party f2.8 lens, but I'd confidently say that Canon 7D is at least one stop quieter than the Oly (I have a Canon and an Oly E 620 personally). So in terms of shutterspeeds, you can just increase the ISO by one stop to compensate.

I'd still say that in terms of dof, the 50-150mm/70-200mm f2.8 lens should probably have about the same or shallower dof than the 35-100mm f2.

Optically, the Tokina 50-135mm and all the Canon 70-200mm varients f2.8 or f4 are excellent IMO so I'm not sure if you'll have any loss of image quality. I'd actually would expect the opposite since the AF performance and the IQ of the camera should be higher.

I just want sharp images with the lens wide open, I think the 35-100 is the best lens I have ever used by far. I did however play with the 85 1.2 on a 5dmkii and it was soo soo sweet.




So to try to understand yuo guys are sayinf I sould be looking at the 70-200 f2.8 but the shortedt focal length is 112mm on a 7d where on the 4/3 it's 70mm I am confused. I

No we said the 35-100 is the equivalent of 70-200 F4 on FULL FRAME, i.e, the 5Dmk2.

Take a look at this explanation of Focal length, crop factor, and field of view. That may help explain things.

Ok I guess I am am unable to explain. I have a 7D. I want the same f2 zoom lens I had on my OLy but on my Canon . I understand 7d is 1.6x (crop sensor).

So There is no Such beast available to a crop camera like the 7d. I will make it clear I want a 43.7mm - 125mm f2 canon zoom lens. Anything like this available.

Last question is it possible have a lens mount changed and re chipped?

There are no f2 zooms for anything but olympus. Get the Sigma 50-150mm f2.8 or Tokina 50-135mm f2.8 and be happy. WE've tried to be clear as well. You can't always get the EXACT same thing in every system, but a 50-135mm f2.8 would be equivalent to a 40-108 f2.2 in olympus-land. Sigma 50-150 would be equivalent to a 40-120mm f2.2. That's close enough, isn't it? If not then you need to consider full frame and a 70-200 or keep what you have.

TK thanks for the time you took to respond, Thanks for everyone else. I was looking for a Canon L lens. I was just preying there would be an equivlant. Isuppose I will have to get the 2.8 zoom and maybe a prime or to. I love the 85 1.2 that is one sweet lens.

Lastly if I could find a Full Frame camera with the feature set of the 7d I would already own it, ;P
