I really don't know you, so I have to rely on instinct. Sometimes, you put posts on here that seem to be quite informative, then, at times, you ruin your image (in my eyes!) when you make statements like you did in this post. I would think you would know that Canon and Nikon both produce outstanding gear. I find it distasteful for anyone to so blatantly put down Nikon and, in effect, Nikon users. I may not be the awesome photographer you are, and I surely am not the "all knowing, intelligent person" you like to portray. But, I would not put down any camera brand or any user of a camera brand as you have done repeatedly. I put very little faith in what you say anymore. Oh, and by the way, I started out my "hobby" of photography with Canon gear. I switched to Nikon, and never looked back, I am perfectly satisfied with Nikon, understanding that I will never reach your stature as a photographer. Have a good day, Sir.

As long as you don't use the calls on some of those apps. It will confuse the bird. Many folks wrongly use these calls to call in a bird, this is so wrong I don't know where to begin.
Lets see, they call in a male bird with a female call, the male bird never finds the female, if done enough times, it can really mess up the male or female depending on the sex call used.
If you are doing this, please, please stop the practice. Practice instead studying the birds you are interested in and find out where they congregate.
The birders will be grateful for your support.

Focal length of a lens does not change. Your 50 mm lens is still 50 mm no matter what type of camera it's mounted on. However, when you put that lens on a crop sensor camera which has a smaller sensor area, as a result of the smaller lens image circle it gives you the impression that your camera has zoomed in a bit compared to a full-frame camera and the focal length has changed. But in fact it is not changed. 50 mm is always 50 mm. What has happened is that the smaller sensor has changed the angle of view and is giving you a full-frame cameras view equivalent to 80 mm. That is often referred to as the crop factor, and for Canon cameras the crop factor is 1.6. When you multiply 50 mm times 1.6 you get the equivalent full frame angle of view of 80 mm.

I have looked these to lenses up on line and I think I have only gotten more confused. Which is the better all round ,quality lens ??

I have the Nikon Nikkor AF-S DX 18-140mm f/3.5-5.6G ED VR and I use it almost all the time ,for everything.

But I saw the Nikon DX AF-S Nikkor 18-200mm 1:3.5-5.6G ED SWM VR IF Aspherical and it stirred up my interest .

I have a Nikon AF-S Nikkor 70-300mm 1:4.5-5.6 G SWM VR ED IF which I was thinking I don't really need . I've hardly ever used it .
The 18-140 is great but I thought the 18-200 would replace both of them . I can't imagine that I would really miss the 70-300, or would I ??
I can buy the 18-200 for $135 like new ,seen it.

Maybe I'm just over thinking the whole thing. I've read the 18-140 takes the better pictures but then I read where the 18-200 takes really good pics

Just looking for some opinions from everyone . THanks

They should, RAW files should initially look worse than your JPEGs. RAW images have ZERO processing. Depending on your camera and the software used to view / edit the RAW, the images will likely have the wrong colors, wrong WB, no sharping, and too little (or too much) noise reduction processing.

When you become a RAW photographer, you become the decision maker for these considerations in post processing, where many had been decided by the camera for the JPEG:

1. Sharpening
2. Noise Reduction
3. Color Saturation
4. Exposure adjustments, general
5. Contrast, general
6. Highlights and shadows
7. White Balance
8. Lens corrections
9. Color space
10. Pixel resolution for target image share platforms
11. Disk storage (for the larger files)
12. Image file back-up strategy (for those larger files)

You don't have to understand all these issues, but when you do, you'll be much more successful as a RAW photographer.
