New 70-200 f/4 and f/2.8 lenses

Canon releases two new lenses that are sure to delight anyone in the system. I will be getting the f/4 version myself, I use it a lot for landscape and event work. The f/2.8 will be a super nice lens, but weight is a factor for me, if you are doing studio and or portrait work though, the f/2.8 will be a killer solution.

With better optics, lens coatings and image stabilization, you can't go wrong getting either of these lenses, its just choosing which best suits your needs.

New Canon Lenses

This is why Canon does so well, they produce top quality lenses that we drool over. the system is what its all about, its not just a camera, or a spec. I shoot Nikon, Canon and Fuji and I prefer Canon and Fuji glass, that's why I'm vested in those systems. Nikon is not far behind and Sony has a ways to go. Its about the system.

Canons new EF16-35 f/4L IS

Diagonal Angle of View: 108°10′ – 63°
Focus Adjustment: Inner focus system

Filters in the digital age


Image: Canon 5D and 17-10 F4 L, Lee 3 Stop GND filter, f11 at 17 mm, no crop.
 Larger Image

Filters are still required in the digital age of photography, not as much as they where in the film days, but in order to get proper exposure on a lanscape that has a very wide dynamic range or to remove reflections from water, we still resort to using filters.




The main filter system in my bag is the Lee Graduated Nuetral Density filter or GND for short. The main task of these filters is to reduce the amount of light contacting the camera sensor while still being able to use the lens aperture you need. Graduated filters, as the name implies, start the transition from the center of the filter and graduate to the edge in varying degrees, measured in stops.

The top photo is an example of where a GND filter is needed, if a filter was not used and you where to meter on the sky the land would be under exposed or if you metered on the land the sky would have been over exposed, in this image a 3 stop filter was used to even out the overall exposure. The filters I use are made by Lee and Singh-Ray I use the foundation kit with 4 x 6 filters, for wide angle I use there special wide angle hood with one filter slot. I carry a 1, 2 and 3 stop GND a 3 stop reverse GND and an 8 stop variable ND. The reverse filter is for shots like a sunset or sunrise where the brightest part of the image is closer to the middle of the image. The variable ND is a great filter for shooting seascapes, this is a filter that I will talk about in another blog.

 The Lee Big Stopper a 10 stop ND filter for maximizing the effect.

Circular Polarizer: The CPL is another filter that is still required for reducing reflections and a good quality filter should be used to prevent color cast's. B + W is my choice, I use the slim 77mm and reducing rings when needed. These filters also increase the color saturation of trees and blue skys and add contrast to clouds, there should be one in every photographers bag. A word of caution on CPL and wide angle landscapes, if you have a lot of blue sky the CPL will only cover part of the sky and you will end up with un-even polarization that will ruin your image.

Sharpest zoom ever ? - Canon EF 70-200 f4 L IS


Photo: 5D MkII and 70-200 f/4L IS, 2 shot panorama

Maybe,
One of the eternal questions for Canon owners is which 70-200 should I get ? Of the 4 to choose from, they are all very good, but with a range in cost of $500 to $1700 how does one choose ?, I have had the 70-200 f2.8 L, 70-200 f2.8 IS L and presently the 70-200 f4 IS L. All three of these len's where sharp. I purchased the original back in my film days and enjoyed it, at one point it was stollen so my re-purchase was the 2.8 IS version (at the time there was no f4 IS), the "IS" or image stabilization is an amazing feature that works exceptionally well. So I had a trip comming up and this caused a problem, which lens's to take with me ? I realy wanted to take the 17-40, 24-105, 70-200, 300 f4 and one body, but these would not all fit in my bag of choice, not to mention the weight would be prohibative to pack around all the time. My solution ? buy the 70-200 f4 IS, try it out and sell the loser. keep in mind that for me the bokeh of the f2.8 was not that important, I have other lens's for portrait shots and the 1 stop differance between f2.8 and f4 is not enough to matter for low light shooting, for that you want f1.4 len's. So after recieving the f4 IS version and trying it out on a skyline shot of Seattle I became convinced, at half the weight, a $600 savings, one stop better image stabalization and getting a sharper lens, to me there was no competition, I sold the f2.8 IS version, in a perfect world I would have kept both, but in these times of economic turmoil, not going to happen. Oh and this allowed me to fit all the lens's I wanted in to my carry on bag, and made my life a lot easier.
So if you want one of these lens's you need to juggle, weight, cost, speed and image stabilization, as far as IQ is concerned, they are all very nice and you can't go wrong there. If its portrait work, its got to be one of the 2.8 versions, I think for most other applications f4 should suit most people fine. Photography has always been about trade offs, this is just another one those.

My recommendations are as follows:

for portrait work: 70-200 f/2.8L IS II

for all other work: 70-200 f/4L IS

for cost saving: 70-200 f/4L



Update: the newest member, the EF 70-200 f/2.8L IS II, at around $2300 trumps them all, yes its worth it, I upgraded to the EF 24-70 f/2.8L II and it is also well worth the money.
