Choosing Lens: Canon 7D

The EF 24-105mm f/4 L IS USM is my choice for a general purpose lens. The EF 24-105mm in the 7D body will have a smaller field of view at the wide angle (equivalent to a 38mm in a full frame body), but on the other end it gives a larger view at the telephoto zoom which I like, it is a fast lens with an constant f/4 stop, the quality of this lens is superb. 

I do miss a wide angle for landscapes, for now the camera kit lens (EF-S 18-135) which has a nice IS will allow me to do a landscape at 18mm f/3.5 of good quality, I am going to stay with this lens for my wide angle needs before I look into a truly wide or ultra-wide lens like the EF-S 10-22mm f/3.5-4.5 UMS.

Canon 7D Auto Focus Issues

Learning how to use the new AF system of the Canon 7D is critical to take good photos, in the beginning many of my photos were out of focus, after a couple of weeks I thought that there was something wrong with my camera or my lens. Here are some tips to take the full advantage of the 19 point AF system of the Canon 7D:

1. Read the Canon Instruction Manual. Don't just glance through it read it!
2. Watch the Training Videos developed by Canon
3. Set you AF Mode to AI Focus
4. Set your Metering Mode to center-weighted average metering
5. Practice several shots with still subjects until you get good shots 

Once you have reach the point of satisfaction with the focus quality of your photos, you can move on to other AF modes.

Lens: EF 24-105mm f/4 L IS USM

I wanted a general propose lens that could cover most of my basic needs of photography. The L series of canon lens are first class lens and the EF 24-105mm f/4 L IS USM (in the 7D the focus range will be 39-168mm) is no exception, weather sealed, very fast and silent. Another that will be a great general propose lens is the EF-S 17-55mm f/2.8 IS USM, this lens is designed only for a camera body like the 7D and it will give an advantage in terms of the wide angle.

Just to recap some definitions about lens:

EF = Name of the canon mount
24-105mm = Focus range of the lens
f/4 = Largest apperture of the lens.
L = A special series of Canon quality lens
IS = Image Stabilized
USM = Utrasonic Motor (fast and quite focus)

This lens has for me the ideal focus range for almost every thing. It is "L series", meaning quality and with image stabilization, for now I have all I need to begin to enjoy the 7D.

From a G9 to a 7D

For a couple of years I used a Canon G9, I just love this camera, with it I gained the desire to take greater control of the artistic side of photography, bit by bit I began to use the manual controls of this camera, of course soon I wanted to have better quality and aditional features that the Canon G9 could not offer.

I knew if I was going to move to another level I needed another camera, but DSLR's look so bulky, I could see myself going around with with such a big camera, than four-thirds came along and in particular the Panasonic GF1, I explored every feature of this camera and for sometime I thought it would be my solution. The price tag and some missing features (like image stabilization) kept me away from a purchase.

The 7D was a big step upwards from the G9 and it was a bulky camera. I study every review online, I looked at costs not only of the body but also of lens, I checked customer satisfaction reports, etc. Video was very important to me in a camera and the 7D could provide quite an improvement in that area.

In the end I decided to keep my G9 as a pocket camera and the 7D for the quality I was looking for! I do not regret the decision.
