Rich Posted October 7, 2011 Report Share Posted October 7, 2011 The Nikkor AF-S 35mm f1.8 Picked the lens up this afternoon and first impression is it's very good, think I'm going to like this I love the bokeh effect so going to try this out on a few subjects. Here's a quick photo I took earlier. Quote Link to comment Share on other sites More sharing options...

Rich Posted October 7, 2011 Author Report Share Posted October 7, 2011 35mm f1.8!!! It's a prime lens with a small f number. It is very sharp, works well in low light and creates the bokeh affect. Quote Link to comment Share on other sites More sharing options...
phipck Posted October 7, 2011 Report Share Posted October 7, 2011 F1.8 means the hole that lets the light into the lens can be opened almost completely, this will let more light in which in turn means that you can capture photos with a very fast shutter speed (capturing moving objects in a freeze frame) and it also defuses or fuzzes the areas not in focus in a way pleasent to your eyes (the bokeh effect) like in this pic Quote Link to comment Share on other sites More sharing options...
Rich Posted October 7, 2011 Author Report Share Posted October 7, 2011 What the man said^^^ What lens did you take that with? Quote Link to comment Share on other sites More sharing options...
phipck Posted October 7, 2011 Report Share Posted October 7, 2011 was taken on my Sony A200 f/5.6 @ 1/500sec using my 75-300mm lens at 300mm. more patience and luck that know how involved with it. What i would give for more apature! Quote Link to comment Share on other sites More sharing options...
Sagitar Posted October 20, 2011 Report Share Posted October 20, 2011 35mm f1.8!!! It's a prime lens with a small f number. It is very sharp, works well in low light and creates the bokeh affect. Have you taken any interesting pics with it yet. 35 mm on a full frame is a good lens for street photography, but I think it's becoming a dying art because everybody is becoming so sensitive about picture taking.

Rich Posted October 20, 2011 Author Report Share Posted October 20, 2011 Nothing interesting yet, just been using it for stuff I'm selling. I'm busy with work and stripping the car ATM but hopefully I'll be using it more soon. I don't think I could do street photography. I know I wouldn't like having my photo taken and I'd be too self conscious of everyone looking at me. Quote Link to comment Share on other sites More sharing options...
phipck Posted October 20, 2011 Report Share Posted October 20, 2011 i think it works best if you are in a really busy area, alternatively becoming a regular feature in a location helps to reduce your noticable presance Quote Link to comment Share on other sites More sharing options...
Sagitar Posted October 21, 2011 Report Share Posted October 21, 2011 I'm not very good at it, but it is amazing how little notice people take of you when they are engaged with other things. I have been spending some time lately getting to grips with a specialist rising-front lens that lets you avoid converging verticals. I have taken dozens of pics of the front of the house and I think I am beginning to get the hang of it, but I still have problems judging when lines are vertical in the viewfinder. I think it was simpler with large format cameras, but they are too heavy for me to carry around. I'll reduce the size of some of the images and print one here for interest.

Sagitar Posted October 21, 2011 Report Share Posted October 21, 2011 35mm f1.8!!! It's a prime lens with a small f number. It is very sharp, works well in low light and creates the bokeh affect. It's very easy to get confused over f numbers. The f number is dimensionless and is the ratio of the diameter of the lens aperture divided by the focal length of the lens. So if you increase the diameter of the aperture and keep the focal length constant you let in more light, but if you increase the focal length and keep the aperture the same, you get less light. A lot of people find it difficult to understand how a smaller f number means more light, but the f number is actually a reciprocal and should be written "f/1.8" (It is often written 1:1.8 on the lens). So, in arithmetical terms, f/1.8 is actually a bigger number than f/2.5. f/1.8 lets in twice as much light as f/2.5 but it is not twice the diameter because the light transmitted is proportional to the area of the lens aperture and the area increases as the square of the diameter. Given how ambiguous and confusing all this is, I prefer to avoid talking about bigger or smaller f numbers and prefer instead to talk of a larger or smaller aperture. So I would prefer to say that your lens is a wide angle lens, with a large aperture. Lenses used to be scaled to show full "stops" i.e. one graduation would halve or double the light transmitted and the most common f number series on my lenses is f/1.4; f/2.0; f/2.8; f/4.0; f/5.6; f/8.0 etc. But modern cameras have graduations at one third of a stop and your f/1.8 lens lets in one third more light than an f/2.0 lens. A good SLR actually achieves much more precise control than this and one eighth of a stop is not unusual. Quote Link to comment Share on other sites More sharing options...
Sagitar Posted October 27, 2011 Report Share Posted October 27, 2011 My apologies - I promised this a few days ago and other things got in the way. Taken with a 45mm tilt and shift lens on a full frame sensor. I used the house as the subject because it has lots of verticals that should all come out parallel if I use the lens properly.
