I enjoy shooting anything with a camera but mostly birds. I take the lazy approach and make them come to me.

The saying that birders can never have enough reach is an understatement.

The big glass is much too expensive and heavy for me although I had a 500mm P f4 several years ago. The manual focus made me miss a lot of shots as birds are very active and my reflexes keep getting slower it seems. When I got it right it was awesome.

Several members here gave me the idea to take advantage of sensor crop factors by using lens adaptors for my existing lenses.

I decided on Nikon 1 and FT 1 adaptor. Ordered a used V2 and adaptor. It will multiply by a factor of 2.7. A 100mm equates to 270mm, 300mm to 810mm and so on. There is no light loss. f4 remains f4 but the DOF increase substantially. Couldn't be better for telephoto.

Now I'm a big advocate of large MP sensors for the ability to make huge crops. I have no illusions about the IQ of my new rig and have no expectation of matching my 810 even when cropped severely.

However there has to be a cross over point where the complete 1" sensor is better that the cropped FF image from the larger sensor, using the same lens.

The new rig should arrive by the end of the week. I feel like a kid at Christmas time. Nothing more exciting than delving into new territory.

I'm going to watch this thread, as I just ordered a Nikon 1 AW-1, for an upcoming water sports vacation. Hadn't thought about the adaptor aspect.

Thanks for posting!

I think you will see that point when the smaller sensor's pixel density exceeds that of the cropped portion of that of your FF sensor by a fair margin. The only real downside should be much poorer low light response.

You're welcome.

Had several M4/3 cameras until last year. The idea of using adaptors for my Nikon lenses never occurred to me.

Missed opportunity.

I agree completely.

What Nikon adapters are you talking about. Thanks

I know you are well ensconced in Nikon. I am well ensconced in Canon - but just sold my 300 2.8 ........

I have the same concerns as you - and have gone to Sony A77II with 1.1-2X Clear Image Zoom. IMHO, this is the best of all worlds for me. I am using the Sigma EX 100-300 f4. The 2X CIZ takes me to 600mm f4. Cost ? the A77 was a refurb - $720 and the Sigma $540 from Japan.

1/800, wide open f4, ISO 500, 1.4X CIZ (420mm)

Nice detail on the image.

I had the Sigma 100-300 f4 years ago. Very good zoom.

The Nikon P/900 has a 2000mm view :thumbup:

I am well aware that you love your P900, but it is not the answer to everything.

How much of that 2000mm is optical and how much of it is digital?

I agree completely.

while I have a 30x bridge camera, my pet aps-c rig is a Sony slt a-65 with a Minolta 500mm af reflex lens. by itself it gives the equiv. of 750mm at 15x. with the 1.4x tc it's the equiv. of 1050mm at 21x, and with the 2.0x tc it's the equiv. of 1500mm at 30x. the last combo is manual focus only. with 24mp's I've gotten some really nice images, I plan a trip to the zoo this week and all me shooting will be with these combos.

if I want to go with the highest IQ my stable wil give me, I go with the Minolta maxxum 70-200mm apo G hs plus their 2.0x tc, I keep auto focus and get the equiv. of 200-600mm. the results so far have been spectacular. the only down side - it's heavy and not suited for action shooting at my age.

I purchased the FT1 adapter when it first came out and created a gallery of photos with it on the Nikon V1. Currently I am using the NikonV3.

Click on the gray circle with an i to the lower right of the large image to see which lens was used. Included is also a photo using it on a Nikon Fieldscope.

The f/stop will not stay the same and the DOF will not increase, but decrease!
