Question: I have just purchased this camera with the kit lens. What would you recommend as a second lens?  I am a casual photographer , mainly family, vacations
Document: I purchased one mail order from Amazon; when it arrived I was impressed with the build quality of both the body and kit lens (which I bought on the advice of existing reviews). All the movements and adjustments are well defined and positive. Not heavy, the camera and lens fit well together and feel rock solid. Though I have relatively large hands, this diminutive camera fits them well and all the controls seem placed precisely where I would want them.
My xt-1 is perfect in every respect. The auto focus is blazingly fast, and the &#34;kit&#34; lens that it came with puts the competition to shame. I'm not a pixel peeper, but I did a couple of 100% crops, and wow I'm amazed. In a pinch I would be perfectly comfortable pulling a 100% crop of something for casual use.
I am impressed.The remote app is brilliant, even my wife and kids loved it, finally able to take family pictures and knowing exactly what I am getting.The Kit lens is fast at AF, no issues even in very dark scenes. Thinking about getting the 23mm but will have to give up my x100s (not going to happen). The other thing which I completely forgot is the weather sealing, coming out of the circus it was snowing hard and I did not worry about my camera being exposed.
Again, small bother. I went ahead and ordered the non-battery grip to see if this helps a bit.Finally, since I made the jump into a new camera body, I ordered the kit 18-55 lens as well. I'm not a zoom lens user but since I have a family with small kids, zooms are convenient at times so I thought I'd take advantage of the package deal. The lens has really amazing image quality and focuses extremely fast and quietly.
I've been using the fuji X100 since 2011, and love the image quality that it achieves, so decided to stick with fuji.I had rented the X-T1 prior to purchasing. I purchased with the 18-55mm kit lens. I'm still in the familiarizing phase, working with the various features. And it has many. I especially like the focus peak option for focus assist. It really helps my aging eyes.
ALL of the Fuji lenses are like top line quality found in the Canon L or Nikkor pro series at half the price in some cases. Sharp corner to corner with large apertures available. I use the kit 18-55 but don't be fooled, this is a &#34;PRO&#34; lens all the way in build and performance. I also recommend the 23mm f1.4 for outdoor and indoor walk around shooting with great subject isolation capabilites. Lastly one of my favorites and a Must Have.
I am a professional photographer of 8 years shooting weddings, family, and boudoir. I will simply say that I sold my Nikon D3 and all it's beautiful, heavy lenses and have completely shifted all my eggs to the Fuji basket based on this camera and Fuji's arsenal of amazing primes. My brain and my back are super happy with the decision.
Normally, I would not purchase a &#34;kit&#34; lens, but this one lives up to the best reviews others have given it.What comes in the box allows one to get started, although I would have appreciated having a UV haze filter included. I did not use the camera until I had one in place.
However, this is mainly a problem with third party lenses (because the lens closes down to the aperture you are actually using while composing itself, hence decreasing light gathered by the sensor and thereby increasing noise)3. Auto ISO: Would've been nice if the minimum shutter speed could be pegged to the lens' focal length (or 1.5 times thereof) since that is how many people would like to program it. However, this feature is not common in most cameras yet.4.
I have no reason to think they are nothing but spectacular, and would be a primary reason for owning a Fuji XF system in the first place. I did not want to spend money on the included kit lens as I plan to get the upgraded pro zoom lens and only the primes I want for my growing compact kit.I can say that the Nikon mount lenses I have tried (with adapter) so far work quite well (in aperture-priority A mode) and with MF.
Answer: I purchased the 56/1.2. What an amazing lens! I have a blast with the portraits now I am able to take. Another great prime lens would be the 23/1.4. I don't have it since I have the X100s as well. My last Fuji lens is the 55-200. Very sharp, well built lens. Took it on an air show and was able to take great, sharp photos on fast moving jets and airplanes. Can't go wrong with it.
