Hi, I am using a Canon T3i on an Epic Pro and will be using the Stitch software.

I’m wondering what I’m capable of achieving with respect to zooming in on a landscape. I’d like to have a really wide panorama of a landscape stitched to a panorama of the same landscape, only manually zoomed into by my camera i.e. I don’t want a purely digital zoom. Is this possible?

Thanks in advance!

Your choice of lens will be the best indicator of how good your results will be. I use a Canon 75 to 300mm zoom at its maximum zoom with a T2i. Same sensor that you have and have very good results, limited mostly by air quality and thermal shimmer at distance. Check out my 360 made using that combination: http://gigapan.com/gigapans/69389. This pano was taken with a modified GigaPan Epic and the setup above. 1859 17.9 Mpx photos were captured on a single set of AA batteries, Canon T2i battery and a 16GB SDHC flash card over a period of 1 hour and 40 minutes. This resulted in my largest GigaPan to date, 12.59 giga-pixels. The Epic Pro battery should also last for this same shot. There is a snapshot of a USAir plane departing Sky Harbor Airport at roughly 10 miles distance. You can see the thermal effects there. Wild Horse Pass Hotel is 2.75 miles away in another snapshot. Haze restricts the ability to see details in that shot.

Bottom line. Use your longest lens, stopped down to f/8 or f/11, manual focus. Nearby objects can be a challenge to deal with in picking the right focus. I chose to focus on the rooftops in the above pan and that resulted in nearby shrubs on the hilltop being out of focus but that was OK. Learn about hyper-focal distance for your lens and using that to choose the optimum focus and aperture. http://www.dofmaster.com/dofjs.html

Also, you should disable the Auto Lighting Optimizer function of the T3i (p 109 of the manual). This is enabled by default and you will have an undesirable contrast compensation that is quite noticeable where bright sky transitions to the horizon objects.

Thanks for your response Dave, that makes a lot sense. I will definitely go out and do some experiments with your suggestions and see what I can achieve. Right now the longest lens I have is a 135mm but hopefully I can manage to get something longer before I go on my trip. We will be documenting petroglyphs in Mongolia and want to be able to see both the rock art up close and the landscape in which it is embedded in the same photo.

Thanks for the tip about the T3i settings as well, I was able to quickly locate it in the menu settings.

I read the link about DOP, but I’m an amateur photographer so I’ll have to read up more before I fully understand it I think (I’m working on an expedition as an intern so I’ve been thrown into all of this headlong!). Basically, you have two areas of the photo which will be in focus based on your lens zoom, focal settings, and aperture – your subject area and your hyperfocal area – is that right?

Thanks again!

I’m now using a Canon T2i on an Epic100 with a Canon 70 to 300mm zoom as my primary GigaPanning setup.

To appreciate the quality of the T2i at full zoom compare these two GigaPans I shot of the Robbers Roost Pluton in the Southern Sierra Nevada Batholith:

1) Canon SX10IS at full zoom (less than optimal light): http://www.gigapan.com/gigapans/51713
2) Canon T2i with Canon EF 70-300 zoom lens at full 300mm zoom: http://www.gigapan.com/gigapans/103988

Even at less than the full 300mm zoom, here’s what the T2i is capable of: http://www.gigapan.com/gigapans/104068

I think you’ll be very pleased – I know I am. :-)

Wow, those are some beautiful photos!

I finally got out and tested the T3i quickly. Definitely would like to get a 300mm lens if possible.

Thanks for your help!
