I would be happy with those results....like the goose.

I think I will try and pick up a secondhand 1.4......once we are over the financial shock of replacing our car.  Bank account has a large hole in it, must be more frugal.

Evidently owl's  are still there, only not showing in strong winds.

Please please take a look on Flickr search for Cosper Wosper under people real name Graham Hall.

You will be as envious as I am of the close up image of theShortie, but it was taken using a 2c converter. However it was an F2.8 lens but shows what is possible with converters. 

 BM ......I wish..................

Cosper wosper  silly name, but what photo's.

Just seen that someone saw SEO at Hardley again.

Some nickname pulled out of a hat for his skittles team I have been told. They could call me anything they wanted if I got shots like that.

Most are taken with a 2x TC and mainly Somerset Levels. Still no Owls in my area, nearest about 40 miles away. Heading down to the levels on Thursday for a stroll and retail therapy for the boss at Clarks village after the Starling murmuration.

Nice shot of the SEO.

Off to Buckenham Marsh tomorrow, hoping to get some large flights of waders/ducks....but I do tend to dip out on these.

Can you explain in simple terms, the benefits or not of a cropped sensor against a full frame sensor.

Chatting to my wife and she is happy for me to upgrade my 70D....problem is to what.

I used to be indecisive...now I just can't make my mind up.

If I can answer, I'm sure BM will give a better answer but a full frame sensor is exactly as the dimensions of a 35mm film. A crop sensor is cropped and smaller than that (sorry if you knew that already). A full frame has more area to capture the light on it and therefore gives more detail when enlarged.

Also a full frame will give better low light pictures at low ISO with much less 'grain' and better dynamic range, but they are bigger and heavier cameras and more expensive.

However would you notice, or rather how much you would notice is the question. BM might be more helpful here.

One last last point your current lenses might not 'work' correctly on a full frame camera. It depends on your lenses. They will produce an image but it won't fill the entire full frame. If you have (Canon) EF mount then they will work on both but EF-S will only work on crop frame like your 70D.

I'm more than happy with my 760D and 70D and might be tempted to get an 80D. There is a 7D which might be a good step up. 

Wow...Corner.....

Good reply...........

Am I right in thinking that a cropped sensor is what you need if you always shoot through a larger lens ie 400 etc, at small objects like birds?

I think I am proving here that I know very little about photography.

I stood for 2 hours yesterday watching an owl sitting on a post 200 yards away and the lazy little beggar never moved.

Hi GL

Firstly, check out the news on cameras as new models will spring up this year due to, world games (coronavirus permitting). Also check out the Sony range as the sensors of most cameras are now provided by Sony, and you can get an adaptor to fit canon lenses to some Sony bodies.

As Cornersteady has commented above a full frame sensor is the same size as the old film format of 35mm.

A cropped sensor has a smaller sensor of various sizes depending on manufacturer. Canon being from memory either 1.3 crop or 1.6, so if we apply that to your set up of 70D which has a crop factor of 1.6 and your 100 to 400 lens. The crop factor makes your lens become a virtual 160mm to 640. on a camera with a crop of 1.6 or 130/520mm with a camera with a factor of 1.3. (100/400 x 1.3 or 1.6

When used on a full frame, the lens remains a 100/400

So using this logic with the pics we take, the crop factor works in our favour.

The advantage of a full frame with many more pixels allows a greater crop post processing while loosing less quality, but where the advantage evens out is dependent on the quality of the elements of camera sensor and lens etc.

I will stop there and answer anything further if I can.

Blimey BM.......

Have to sit down and digest.
