Resolution Chart Comparison (JPEG)

Shots here are of our 'version two' resolution chart which provides for measurement of resolution up to 4000 LPH (Lines Per Picture Height). A value of 20 equates to 2000 lines per picture height. For each camera the relevant prime lens was used. The chart is shot at a full range of apertures and the sharpest image selected. Studio light, cameras set to aperture priority (optimum aperture selected), image parameters default. Exposure compensation set to deliver approximately 80% luminance of white area.

Measurable results

Camera Measurement
Canon EOS 7D Horizontal LPH 2500  * 3100 
Vertical LPH 2450  * 3050 
Canon EOS 50D Horizontal LPH 2250  2700 
Vertical LPH 2200  2700 
Nikon D300s Horizontal LPH 2200  2300 
Vertical LPH 2100  2600 
Pentax K7 Horizontal LPH 2300  * 2700 
Vertical LPH 2250  * 2650 

* Moiré is visible
+ Chart maximum
LPH Lines per Picture Height (to allow for different aspect ratios the measurement is the same for horizontal and vertical)
Absolute resolution Point at which all lines of a resolution bar are still visible and defined, beyond this resolution loss of detail occurs (below Nyquist frequency).
Extinction resolution Detail beyond camera's definition (becomes aliased)

The Canon EOS 7D makes the most out of its 18 MP sensor and delivers the highest resolution that we have so far seen on an APS-C DSLR. There are some signs of moire at very high frequencies but it outresolves all other cameras in this comparison in terms of both absolute and extinction resolution. However, when looking at these results it has to be considered that they, like in all our studio tests, have been achieved with stopped down prime lenses. In most real-life situations you would struggle to get the same amount of resolution in your images.

Oh it is a Canon EOS 7D


I was busy shooting today, battery full, CF card in the camera and everything went black? It will not switch on at all?
Have checked the battery - put my spare in, also fully charged but still no luck?
I was using studio lights - so does that effect the camera?


If you were using the PC Sync or hotshot to sync the flashes, they may have a trigger voltage beyond what the camera can handle. If that was the case they may have smoked your camera. There are companies that make trigger isolation units to protect the new modern cameras from the older strobes that use high voltage sync. Have your camera looked at by a repair shop or canon to determine if it is worth repairing.

I've been struggling to find the replacement for my 5 year old Canon 40D. The images from the 40D are excellent, but it is technically behind times.

When the 7D was first released, I bought one, but returned it because of what I perceived as sensor noise. Bad decision on my part! The camera was technically all my 40D is not. So, now that there are scant few left as the shelves clear for the 7D Mk II, I just ordered a brand new 7D (not Mk II) at a bargain basement price. I can't wait to revisit this incredible camera once again.


Hey! I'm curious what bargain basement price you paid for your 7D?

I am curious, also.


Does anybody know if a Canon 7D will be compatible with a Canon 17-85mm IS and a Canon 70-300mm which I currently use on my Canon EOS 450D?

Any feedback on what people think of the 7D would be greatly appreciated as I am considering purchasing one.

of course. why not. its apsc


Yes, it is.


I bought this camera (body only) about 4 years ago with a 24-105mm f4 L IS USM lens. After using it for about 8 months, I compared it side by side with a co-worker's T2i (with various lens). In each case I noticed that the T2i had a sharper (cleaner) image. I was very disappointed. Tried the in-menu focus compensation... didn't work. Finally sent it back to Canon. They fixed it under warranty. It has been good ever since. I shoot mostly my kids at their sporting events... track n field, cross country and tennis. All outdoor sports, so about 2 years ago, I purchased the 70-300mm f4-5.6 L IS USM lens. Both lens work really well with the camera... very sharp results. I would say about 90 ~ 95% of the shots are keepers.


I bought this monster yesterday. <3


I think there was a lot of cutting and pasting in the review. They referred to the 15mp image files and the 18-55 kit lens when they meant the 18-135 kit lens as shown in the product photos and referred to in the intro.

I think that initially looking at the Canon 7D MK II’s specifications they might seem conservative, but as with the EOS 5D Mark III and the 1D X updates to these models were refined, with well measured features that met the needs of photographer in quality and reliability, rather than boasting headline hitting new technological advancements.

I love this camera/disappointed in Canon/customer support/service. The 1st 7d I purchased had a pixel issue. Seems to be notorious in Canon lenses. My 1st PowerShot S2 IS had a pixel issue. I didn't realize was present until camera was out of warranty-had to fight like a dog to get them to replace it. My 7d SAME issue, issue found after first test shots I took in the store downloaded! Didn't want the store to send it back only to send a "fixed lens" I returned it, bought anothernew 7d, but still a problem. Once again found a mo after warranty when a little bracket inside the lens was detached from inside, only 1 screw was holding it in place, there was supposed to be 2 this bracket keeps the extension within the lens. A quality control issue that went unnoticed during manufacturing according to the camera guy that had to fix it but it didn't matter the damage to the focus computer chip inside had already been damaged & Canon refuses to do a thing about it par for the course.


I've just switched from Nikon to Canon and am completely lost, I shoot birds in flight a lot and cannot get my head around how to engage burst on the 7D, can't get built in flash to "raise it's ugly head" also how to change menu settings. Wish Canon had stuck to more universal icons and menu.
Despite all that was very impressed with fast focus on few single shots that I took
Could any one please help?


Little late, but it's called the "Q" button, which is for quick settings. Select the square and change it to multiple stacked squares for burst.

Pop up flash only comes up automatically on the green auto box i believe. I prefer to never use flash, so i forget.

If you have a filter fitted to protect the lens try shooting without. After buying my 100-400 lens I returned to the shop after finding my images soft using a 7D. They tested my lens with a second one they had in the shop and agreed the first lens was faulty. When I got the second lens home I found it as poor as the first until I realized the second lens tested had not had a filter fitted when tested in the shop and I had transfered my filter to the second lens when I got home.
Conclusion: I only use filters for effects and I have remove all my "protective filters" from my L lenses. Why spend hundreds of pounds on lenses just to add a piece of cheap glass on the front.

I am 7D user and have noticed that my images are considerably soft. I mostly use canon 100-400L lens. Initially I thought that its problem with the way I use camera. I tried all possible things. Searched lot and found many discussion about AF problem with 7D. Can someone share their experience?
It seems 7D AF is not consistent although manual focus gives considerably crisp and sharp image.

I'm a wheelchair user and have gone for the 7D because of the increase in range when using a shorter lens over full frame which means though I often cannot get close I often achieve a useable image.

Live on the coast so to avoid problems re dust on the sensor from the beach I purchased a second one a few months back which says, I think, just how pleased I am with the product. Re low iso and noise, possibly because of high light levels from sea reflection and living in a flat open area I personally find no problems but using 2.8 lenses helps. Not professional but have had people use my stuff on their websites - so for my needs the 7D works well - Oh, and if like me you have poor dexterity you'll find the raised buttons really helpful even when wearing gloves.

I have a 70D, am getting a used 7D at $ 800 next week, will provide a comprehensive review after that


My Review of the Canon 7d as the owner of one for 1yr is this.I shoot Professionally and have used the 7d for just about 1yr.It is a bit bigger,heavier than my other EOS Canon's.Picture quality is top of the line.Video quality is top of the line.The Grain Factor when using the ISO at a higher number is compensated by a setting in the Menu so no problem.At 8fps continuous it stands above the others.Weather proof as well (Body only).Recently my Canon 7d was knocked over while mounted atop a 6ft tripod landing on solid asphalt.A little scratch on the body was all the damage it received.Though bigger and heavier the construction,function,image quality of this Camera is incredible.I shoot Landscape,Portrait,sports(MMA Fights) and everything in between.Canon went above and beyond with this model.A+ is the grade I give for this one.


Which one is a better model 70d or 7d , I have read numerous reviews and seen plenty of videos, even though 70d is a much newer version I would like to know from some one who has used them side by side.


I think both are great, depends on your needs, the 7D is like a tank, the build quality is incredible, its AF is phenomenal (a cut above the 70D in terms of customization options), the 70D has slight advantage 2/3 of a stop at higher iso's, has wifi and touchscreen, the 7D has bigger and better OVF, and the 70D have awesome video capabilities. I played with both and went for the 7D (easy choice), the 70D felt like a toy and I didnt like the plasticky feel (compared to the 7D). Bit both are great, you'll enjoy either depending on your needs.


what is max usable ISO on canon 7d?
