Question: Is the lens included with this? Also, the lens is interchangeable, correct?
Document: The fact that the lens was not interchangeable was not an issue for me as the X100 lens is a 23mm f/2.0 - the perfect focal length as far as I was concerned. The 35mm equivalent of 35mm would have been my favorite focal length with the D3100 and the GH2 but neither Nikon nor Panasonic makes a compact and light prime lens that has a fast 35mm in 35mm equivalent (Olympus makes a m4/3 17mm but it is just f/2.8). That the X100 lens was also a fast f/2.0 lens was definitely an ace in favor of the X100.
from what i have read a slow SD card speed can contribute to a laggy boot(i only have 30/45mps cards so i cannot test otherwise).More of a wish not really a Con3) fixed lens - for me the lens that fuji has created for this system is amazing, however when and if they do offer a Finepix X series that does allow for interchangeable lens it will take this lil dream machine into a whole new level.i also highly recommend theRainbowimaging Combo (3-in-1) Filter Adapter Ring + Metal Lens Hood + 49mm Pro1D SMC UV Filter for Fuji X100, Replaces Fuji LH-X100 & AR-X100in place of the fuji branded version
The film simulation modes do a very good job at simulating fuji provia, astia, and velvia films as far as their color rendition. The cost is also mentioned as a detriment in many reviews, and ,while the camera is expensive, I think it's worth the cost given it's image quality and low light performance. Other Interchangeable lens cameras such as the Panasonic GF2 and Olympus E-PL2 start to approach the price of the X100 when you add in things like a fast pancake lens and electronic viewfinder. For example the E-PL2, which I think is probably the closest competitor in terms of image quality outside of a full DSLR, with a 17mm 2.8 lens and electronic viewfinder will run you about $1050.
On the X-100, it all just makes sense. Want shutter priority? Select your shutter speed and it's done. Want aperture priority instead? Just choose your aperture, and it's done. It's that simple. Of course you can go fully manual as well. Set your shutter speed or aperture as needed, the viewfinder shows whether your exposure is correct or not, through the lens, just like in the old days. Perfect. Exposure compensation? RIght on top, where it used to be. About the only time you need to go menu diving is to pull up the ND filter, or to do auto-bracketing.
Personally, no, but not because of the sticky blade issue. For my own purposes I would prefer an interchangeable lens version of the X100, and apparently Fujifilm will announce just that in 2012. It'll no doubt be more expensive than the X100 but I'm more than willing to pay up for that.If interchangeable lenses were not a requirement for me, yes, I'd buy the camera again. The image quality is just that good.
Some say the menus are not intuitive and difficult to navigate.You figure it out and use it. After a while you don't have to figure it out.Non-Interchangeable lens:It's a 35mm equivalent. The only 2 lenses that I ever use are 28 and 35mm so once again a non issue for me.Funky filter issue, lens cap and lens shade:Yeah the filter ring thing is kind of stupid but once you do what you need, it's not. I purchased an aftermarketlens shade which was 110.00 less than the Fuji.
My kit was a GH1, GH2, and X100. I left all of my Nikons at home as they are too big and heavy. With interchangeable lenses and fast handling the GH cameras can cover almost every conceivable shooting situation. With a fixed lens and slow handling the X100 is limited in what it can cover. However, it makes you slow down and really set up the shot the way you want it. The DSLRS and M4/3 are so fast that it is easy to reel off a number of good shots.
We are spoiled when it comes to cameras now. There are a million great choices with better ones coming out seemingly every week. Why would you get this camera or the new X100s rather than one that is faster at focusing, has interchangeable lenses, or all the other features you may think you want? I would say simplicity and image quality. With this it is all you have, and all you have to worry about. No additional lenses. Heck, no additional focal lengths through zoom even, so you get used to seeing the world through a 35mm lens (same equivalent as the iPhone for reference).
If you expose for a shadowed face on a sunny day, you'll clip the highlights just to get enough brightness on the face. This takes care of all of that without you even knowing it.-EVF. Very cool, though I rarely use it.Cons:-Price. It's expensive but not overpriced, there's a difference.-No zoom or interchangeable lenses(relative con). You'll have to just use your feet. On one hand, it's a disadvantage to not have the ability to switch the lens out for a zoom or tele, but on the other hand THIS lens was made for THIS sensor on THIS camera with THIS camera's geometry.
This camera is a great addition to a photographers bag. If you don't shoot fast moving objects/people, I highly recommend.If you don't require an interchangeable lens, think about this one seriously.Reviews have mentioned that the menu system is non-intuitive ... what camera system is? (Nikon, Canon or otherwise)  It's all what you're used to and familiar with. I spent a day reading and playing around with the functions and it wasn't a long before I felt comfortable with it in finding things.Realistically, this camera isn't really for a novice to get the full benefit from it's features and intended use.
Answer: No it isn't interchangeable.
