What Nikon lens can I get to have this kind of focus?

I've got a macro Lensbaby and the standard lens that comes with a Nikon D3000, but I'd like to obtain this look with some of my photos:

And with my lenses, you have to get really close for that, and even then it's nowhere near as soft. But then again, I could just be being a noob. Please inform me. XD

The first shot is a prime example of using selective focus, but in this case, since the lens used is so wide, the probability is that a process called "miniature effect". Some cameras like the Nikon D3200 has such an effect in the cameras "retouch" menu

Some photo programs have the same effect available

The second could be shot using your lensbaby with its aperture wide open and the focus on the lighter. It can also be accomplished using a medium telephoto lens with the aperture wide open

What you want is Depth of field. I would go for a 70-200mm 2.8 lens.
watch this video, it would help you a lot, I know it helped me a lot.

Your lensbaby is the perfect tool for these kinds of photograph, in fact it should be possible to take something that looks better than the first image, thanks to the ability to tilt the lens. It may be that when using the lens baby you are tilting the lens in the wrong direction though, depending on what you are trying to do it can be counter-intuitive. I'll admit the lensbaby takes some getting used to, both the way it works, and your getting used to framing your subjects. It should be easy to get very close to the selective depth of field you want using the lensbaby, though changing apertures is a pain, but the only lenses that come close to it's ability to defocus backgrounds are expensive prime lenses. If you use the "soft focus" optic and aperture rings (or make your own with a blank ring and a drill) you'll achieve a look that you can only other wise produce with some really specialized kit). I can't see the issue with getting close up either, as even with out either macro kit the minimum focus distance in more than enough to achieve either image.

The lensbaby macro kits are really quite something. The add on lenses because they are made specifically for this lens optically outperform any similar add on filter mounted glass on a standard lens that you'll find.

Sorry if, I'm gushing there somewhat, but lensbabys are great "toy" lens. It's not that the results are unpredictable in the way that lomo cameras are, it's more that they encourage you to "play".

I'm going to vote for the 70-200 VR f/2.8 also, for the one on Flickr.

There could have been enough room there to use the 70mm end with the scene we see.

The second could easily be a Lensbaby.

Is not lens only is way you take photo on tripod and use one point focus on your camera not all focus… Is called deep in infield… Your lens if have 3.5 also is fine for this job but 2.8 is better
